Smart and pre-paid metering

by Team Digireach

How do we make the existing state utilities more efficient and bring down their losses? Smart prepaid electricity meters are one of the answers.

This step is likely to bring revolution in power sector by way of reduction in AT&C losses, better health of DISCOMs, incentivising energy conservation, ease of bill payments and doing away with the paper bills.

Smart meters are a part of the overall advanced metering infrastructure solutions (AMI) aimed at better demand response designed to reduce energy consumption during peak hours.

India plans to change all electricity meters to prepaid smart meters by 2022. This step taken by the government is to address the issue of energy efficiency and optimization. Electricity is the need of the hour. Electric power generation is a prime component in the development of a nation. It is the base to move any developmental activity in the right direction. Hence, it is being addressed on an urgent basis with help of schemes like IPDS (Integrated Power Development Scheme), RT DAS (Real-time Data Acquisition System). Energy metering system etc.

  • The government believes that the plan will increase distribution substation capacity by 38% by 2022

India has a beleaguered power sector. Proper monitoring and tracking of energy usage via smart meters would go a long way in addressing the problems of the existing energy infrastructure. The strategy is part of the government’s electricity distribution plan prepared by the Central Electricity Authority (CEA), India’s apex power sector planning body, and comes at a time when the new government is trying to step up its efforts to supply 24×7 power to all.

Creating a smart meter architecture minimises human intervention in metering, billing and collection process and helps in reducing theft by identifying loss pockets. It requires a two-way communication network, control centre equipment and software applications that enable near real-time gathering and transfer of energy usage information.

Smart metering would empower consumers with tools to help them conserve energy and plan their electricity usage in an efficient and optimum manner.

The plan of introducing smart meters is part of government’s plan to fix the power sector in the country. Stopping the unwanted pilferage and making consumers accountable for the usage and wastage will usher India to a new dawn of electricity.

Smart meters, electricity usage tracking, reducing wastage and cutting down on the transmission and distribution losses are the need of the hour.

What IPDS brings?

by Team Digireach

It is a flagship programmes aimed at increasing energy access among the poor. The IPDS is aimed at enhancing the power infrastructure in urban areas

Agenda of IPDS are as follows:

  • Reduction in AT&C losses
  • Establishment of IT enabled energy accounting/ auditing system
  • Metered consumption
  • Improvement in collection efficiency

Energy losses occur in the process of supplying electricity to consumers due to technical and commercial reasons.  The technical losses are due to energy dissipated in the conductors , transformers and other equipments used for transmission, transformation, sub-transmission and distribution of power.  These technical losses are inherent in a system and can be reduced to a certain level.

Pilferage by hooking, bypassing meters, defective meters, errors in meter reading and in estimating un-metered supply of energy are the main sources of the commercial losses owhen Commercial losses are added to Technical losses, it gives Transmission & Distribution (T&D) loss.

There is another component of commercial losses, which is attributable to non-recovery of the billed amount, which is reflected in collection efficiency. T&D losses together with loss in collection give us Aggregate Technical & Commercial (AT&C) losses.

Transmission & Distribution losses (T&D losses)

T& D Losses = { 1- (Total energy Billed/ Total energy Input in the system)} x 100

Aggregate technical and commercial losses (AT&C losses)

AT&C Losses = { 1- (Billing Efficiency x Collection Efficiency) } x 100 Where Billing efficiency= Total unit Billed/ Total unit Inputs Collection efficiency = Revenue collected / Amount Billed

Energy accounting is a system used in energy management systems to measure and analyze energy consumption to improve energy efficiency within an organization. Dashboards and sensor infrastructure can be arranged to collect and monitor data pertaining to energy parameters on a real-time basis. These systems can be used to track energy usage.

IPDS scheme, apart from ensuring 24×7 power supply in urban area, will also help in improvement in billing and collection efficiency which will ultimately result in reduction in Aggregate Technical and Commercial (AT&C or distribution) losses.

These are some of the advantages India can assume on successful implementation of IPDS technology.

Advantages of IoT in Solar

by Team Digireach

Renewable sources of energy are the way of the future. One of the primary sources of this alternative form of energy is solar. It’s abundant, it’s clean. It is the fastest-growing renewable energy source in the world, increasing in worldwide capacity by an average of 40 percent every year.

The Internet of Things Technology for supervising solar power generation can greatly enhance the performance, maintenance and monitoring of the plant. IoT can enable us to do intelligent fault detection and power optimization.

Photovoltaic (PV) array analytics and monitor is necessary for remote farms. Monitoring the solar energy incident on the panel can help us evaluate and plan the energy generation. Auxiliary electronics need to be attached to each solar panel to make this monitoring a reality. Real-time data generation of the efficiency of solar panel can help us sense the trend in solar array effectiveness and robustness.

In addition to providing companies with real-time alerts, leveraging IoT in solar energy can lead to improvements in smart metering. This makes energy production more efficient both in terms of cost and logistics. Solar contains a diverse portfolio of rooftop projects located across the city or large scale project installation in remote locations where high sunlight incidence is prevalent.

It is vital to track the data collection. Digital Reach provides the resources and installation expertise to handle the tracking of relevant data. The solar plant data for a range of parameters covering modules, inverters, arrays etc. are captured. The interval at which the data is captured can also be regulated as per the requirement. This data serves as a basic building block for further optimization and assessment of the working of the plant. Necessary changes and adjustments can be done to extract the maximum possible output from the existing installation.

The data which gets collected from the assembly of sensors can provide an array of reports that integrates power generation estimates. Data visualization options can be integrated in the software. The operator or the management can play with the appropriate display of relevant data, KPI construction, dashboards etc. to facilitate easy analysis.

Other operation and maintenance (O&M) details such as log report/ attendance of personnel/ service and other data can be integrated into the dashboard so that the management gets a holistic perspective of at the plant level. Also, the data which has been collected over a period can be integrated to new-age technologies like Machine Learning (ML) and Artificial Intelligence to gather more insights.

Energy industry – Smarter, Efficient, Distributed.

by Team Digireach

Optimizing maintenance schedules can significantly improve reliability. Preventative measures taken to improve reliability by keeping equipment in optimal condition and detecting problems so that necessary repairs can be done before it fails.

The energy sector is undergoing a massive transformation. IoT sensors measure parameters such as vibration, temperature and wear to optimize maintenance schedules.  Data and other energy parameters are tracked via energy meters. In addition to providing more information to utilities, IoT technology can help customers to be more informed about their energy usage. Internet-connected smart meters collect usage data and send it to both utilities and customers remotely.

The data collected can be used to generate reports. Based on these reports, action can be taken by the utility companies or the customers at a personal level. The reports and graphs can enable the authorities to take action and optimize the energy consumption by identifying leakages and optimizing generation, transmission and distribution.

IoT technology has improved to a great extent in the electrical utility sector. The data collection points, memory space, data processing at the edge-level or the cloud-level can be chosen appropriately so that optimized data collection and preventative action can be taken.

IoT technology can enable the integration of more distributed resources into the grid, but it can also improve grid management in other ways as well. Placing sensors at substations and along distribution lines provides real-time power consumption data that energy companies can use to make decisions about voltage control, load switching, network configuration and more. Some of these decisions can be automated.

Sensors located on the grid can alert operators to outages, allowing them to turn off power to damaged lines to prevent electrocution, wildfires and other hazards. Manual activity of isolating problem areas takes up a lot of time and leads to unwanted losses.  Smart switches can isolate problem areas automatically and reroute power to get the lights back on sooner.

Load forecasting is another aspect of smart power of the future. Power usage data is already collected using an assembly of IoT gateway, cloud, processing power and memory. There are pockets of high power generation and high power consumption both region-wise and time-wise. Load forecasting can help in managing congestion along transmission and distribution lines and help ensure that all of the connected generation plants meet requirements related to frequency and voltage control. This power consumption data can also help companies decide where to build new infrastructure and make infrastructure upgrades. More informed decision and investments in the power sector can go a long way in providing reliable power capacity for each location.

The IoT is transforming nearly every sector of our economy, including the one that powers — the energy sector. Over the coming years, the energy industry is going to get smarter, more efficient, more distributed and more reliable, thanks in part to the IoT.

IPDS for sub transmission & distribution network

by Team Digireach

India is a developing country. Power is the mainstay for any growing country. In order to leapfrog into the future, efficient utilization of power generation is of prime importance.

Electricity is the most important factor in the economic growth of any country. And the most critical segment of Power Sector chain including Generation, Transmission and Distribution, is the Distribution Sector. Efficient management of the distribution of electricity sector is mandatory as it acts as an interface between the utilities and the consumers. The real challenge in the power sector today lies in efficiency. However, the poor financial health of the distribution utilities in the States has resulted in inadequate investment in the distribution network making it difficult to meet the increasing demands of power in urban areas.

The goal of IPDS (Integrated Power Development Scheme)  are as follows:

  1. Strengthening of sub-transmission and distribution network in the urban areas;
    Metering of distribution transformers /feeders / consumers in the urban areas.
    3. IT enablement of distribution sector and strengthening of distribution network

The problems the government tries to address by implementing this scheme are as follows:

AT&C losses [The concept of Aggregate Technical & Commercial losses provides a realistic picture of loss situation in the context it is measured. It is combination of energy loss (Technical loss + Theft + inefficiency in billing) & commercial loss (Default in payment + inefficiency in collection).]

  • Establishment of IT enabled energy accounting / auditing system,
  • Improvement in billed energy based on metered consumption
  • Improvement in collection efficiency.

This is a part of the Indian government scheme of Restructured Accelerated Power Development and completion of the Reforms Programme (RAPDRP). It is a flagship programme of the Ministry of Power.

IPDS is important for a brighter future which will help enhance the economic growth of India. Electricity is vital for the overall development of the nation, and the Union Government by launching this scheme is all set to push India in the right direction of development.

Status as per No. 8/2/201 8-IPDS(Pt.) Government of lndia Ministry of Power

Projects worth Rs.30,005 Crore (Distribution Strenglhening work: Rs 2.7,626 Crore in 546 circles, IT enablement: Rs 985 crore in 1931 towns, ERP Rs 640 crore and Smart Meting: Rs 754 crore) have been sanctioned.

Better electricity leads to a better tomorrow. We, at Digital Reach are equipped with the hardware, software, system integration capabilities and domain knowledge to make this a reality.

RT DAS and AT&C Losses

by Team Digireach

RT DAS consists of two distinct important terms.

Data acquisition system is the accumulation of data. Real-time means its is based on the time at which it is performed. The delay of data collection is insignificant hence it is real-time. The time delay of transfer of audio signals when we are in a telephonic conversation is called real-time. The person receiving the audio signals is able to initiate conversation based on the audio input he gets from the speaker in real-time. The response is immediate. Having a delay in the data capturing technology will lead to a system failure in certain circumstances.

 

The other part is acquisition and storage. Collection of important parameters leads to study of the functioning of the system. The operator or administrator can plan accordingly and take preventive action which can increase the efficiency of the system. The purpose of any data acquisition system is to gather useful measurement data for monitoring and control.

Major areas of concern in the power distribution sector are high AT&C loss and poor power distribution reliability.  Hence, RT DAS comes into the picture. To address these problems, accurate measurement, diagnosis and remedial action is essential. Some of the parameters based on which the reliability of power is measured in the terms of SAIFI and SAIDI which requires solution based on real time.

To accurately measure reliability of power distribution network and facilitate utility to take suitable administrative action for enhancement of power reliability. The measurement of reliability shall be ensured by a real time data acquisition system (RTDAS) using RTU at substation.

AT & C LOSS(Aggregate Technical and Commercial Loss)

In absence of feeder metering in the past, there was huge losses in terms of T&D and theft of electricity in agricultural consumption. Agriculture consumption is around 25%, utilities were showing I as 40% and correspondingly T&D losses shown as 25%. There was obviously a large amount of theft. T&D loss figures did not capture the major gap between the billing and the collection. AT&C was introduced to get over this particular problem.

What is AT&C loss?

  • It is the difference between units input into the system and the units for which the payment is collected.
  • It is the clearest measure of overall efficiency of the distribution business.
  • AT&C measure both the technical and commercial losses.AT&C Loss(%) = (Energy Input – Energy Realised) X 100

IPDS (Integrated Power Development Scheme)

by Team Digireach

We are moving to an energy intensive world. Among the different stages of electricity generation and consumption, distribution is a primary area where we can make necessary adjustments in the power sector value chain to increase efficiency drastically.

One of the features of the Indian power sector reforms is the increased attention to the distribution sector. Systems and procedures for monitoring Quality of Service (QoS) of distribution utilities have been finalized by State Electricity Regulatory Commissions, especially subsequent to the Electricity Act 2003.

Distribution is the most important link in the entire power sector value chain.  As the only interface between utilities and consumers, it is the cash register for the entire sector. Under the Indian Constitution, power is a Concurrent subject and the responsibility for distribution and supply of power to rural and urban consumers rests with the states.

Systems to improve consumer interface, quantify performance and to monitor progress in a transparent manner are necessary and welcome steps. QoS process meets one of the many long felt needs to improve distribution sector. At this initial stage, it is crucial that the distribution utilities and regulatory commissions show serious end to end commitment in the QoS process. This includes the steps of formulating the system, reporting performance, monitoring progress and taking corrective measures. It is also important to proactively work for the active participation of consumers at all stages of the process. With such an approach, over the years, QoS process can evolve to be the necessary and sufficient condition for continuous improvement of the distribution sector.

Government of India provides assistance to states through various Central Sector / centrally sponsored schemes for improving the distribution sector. Integrated Power Development Scheme (IPDS) approved on 20.11.2014 with a total outlay of Rs 32,612 crore which includes a budgetary support of Rs 25,354 crore from Govt. of India. The objectives of scheme are:

  • Strengthening of sub-transmission and distribution networks in the urban areas
  • Metering of distribution transformers / feeders / consumers in the urban area.
  • IT enablement of distribution sector and strengthening of distribution network
