TERI’s Renewable Energy Based Smart Mini Grid Is India’s First

The Energy and Resources Institute (TERI) has come up with an awesome technology- the renewable energy based SMG (Smart Mini Grid) for homes and offices. TERI was sponsored by Government of India’s Ministry of New and Renewable Energy (MNRE) in this project. It is the first of its kind Smart Grid in India. TERI along with its associates and development partners used advanced digital and control methods as well as algorithms for implementing this awesome project. This novel SMG was commissioned by Dr. Farooq Abdullah, Union Minister for New & Renewable Energy. Sushil Kumar Shinde, Union Minister for Power and Dr. RK Pachauri, Director General, TERI were also present on this occasion.

Once these digital SMGs are successfully installed at the electricity distribution level, a host of problems such as irregular power supply, sustainability, reliable quality power delivery as well as power security can be addressed with much ease. These cool smart grid systems can be efficiently utilized for solving the electricity related problems in India’s rural as well as the urban areas. This smart mini grid system is more advanced as compared to the conventional mini-grid systems. It increases the energy efficiency significantly because of its better reliability flexibility, safety etc. in the overall power distribution network. This SMG system is very versatile and can be utilized in a lot of applications. These applications range from residential areas, to educational institutions, rural and suburban locations, industrial setups, commercial complexes, shopping malls, hotels, hospitals and even at telecom base stations.

One of these SMGs has been installed at The Retreat, TERI, Gual Pahari facility. It receives input power from a number of nonconventional and conventional sources such as solar photovoltaic system, wind electric generator, biomass gasifier system, and battery storage system and diesel generator in the descending order or priority. The smart grid network intelligently monitors and balances the power to a number of different loads with the assistance of these varied renewable energy sources. It has better response time. Also, it is capable of dealing with black outs and input power fluctuations earlier than the conventional power grid networks.

A Smart Mini Grid system operates at or below 11 KV rating and intelligently distributes the electricity as per the requirements of the blocks. Its sophisticated communicating, sensing and controlling features enable it to efficiently generate, manage, distribute and utilize electricity at the local distribution levels. It accommodates many DERs (Distributed Energy Resources) and all the energy is stored in the common grid. The smart grid takes very less time to detect, investigate, scrutinize, respond and reinstate itself in case of any trouble. To meet all the demands and optimize the usage of all the resources it uses the special Smart Hybrid Controller/Intelligent Dispatch Controller which allows it to have a centralized monitoring.
