Working Group 3 and 4

Working Group Name : Metering and Communication

Chair Person : AjoyRajani, Reliance Infrastructure Ltd


Introduction

Electricity distribution systems are undergoing rapid changes due to deregulation, the penetration of distributed generation, power electronics technologies and the adoption of efficient metering, communication systems and consumer awareness. Communication infrastructure is one of the backbones of smart grid. The key enabler for the smart grid is the availability of two-way data communications in real-time across the system, which will monitoring and control the power flow along grid in an effective and reliable way. Information and Communication Technologies facilitate utilities to remotely locate, isolate, and restore power outages more quickly, thus increasing the stability of grid. Metering is the lynchpin of a smart grid, and advanced metering infrastructure (AMI) means different things to different people. The evolution of meters from electro-mechanical to digital is just the start of the added functionality / intelligence that smart meters can provide. Digital meters can not only store more data with greater resolution, they become the interface between consumer and utility, with advanced features such as bi-directional communications, remotely controllable connect/disconnect switch, and load control signaling. This extends functionality far beyond automated meter reading.The selection of communication technologies will depend on the envisaged application. For mission critical applications such as SCADA, Substation Automation etc., security, reliability and latency will be the key criteria for deciding a communication technology. Cost will not be the main criterion. For non-critical applications such as AMI, Electric Vehicles etc., cost will be decisive.

Objectives

To study and recommend most suitable, sustainable and scalable communication technologies that can be adopted in India for all building blocks of smart grid in a continuum fashion. The WG focuses on analysing various communication technologies with due consideration to the total cost of ownership (TCO) in the Indian context. Another important aim is to assess the metering scenario in India, identify the goals and requirements. The WG can extend the additional design and standards requirements with respect to communications and metering in a smart grid.

Scope

1. Facilitation - By conducting on-ground assessment of various communication technologies and options in the Indian context to suggest the optimal choices for the success of the envisaged SG projects
2. Benchmarking - Study, analyze and recommend global technologies and their feasibility in the Indian context, and identify gaps that necessitate solution updating/adaptations or even new solutions
3. Best practice creation and recommendation
4. Ecosystem Management - Coordination with other WGs, policy advocacy groups and awareness building for the best technological aspects in the relevant arena
5. Study of country wide metering and billing practices
