Abstract

Increasing penetration of uncertain and intermittent renewable energy sources can cause various problems in grid such as frequency variations, voltage fluctuations and demand- supply imbalance. India is having an ambitious target of adding 175GW regeneration to the grid by 2022, which may bring more challenges to the grid operators for safe and secure grid opera- tions. However, a fast responding storage device such as Battery energy storage system (Bess) could be used to mitigate these challenges in real time operation of power system through vari- ous grid applications including Frequency regulation, energy time shift and re firming etc. at present, many battery chemistries are available in the market suitable to various grid scale ap- plications. However, each chemistry has its own merits and demerits depending upon its tech- nical characteristics. this paper discusses about various operational challenges of different bat- tery storage systems in real time grid integration applications. real time implementation of li- ion, advanced lead acid battery systems of 1MW capacity has been considered for this study. the study would also provide insights on regulatory and commercial framework to be adopted by regulators in allowing large re integration in Indian grid scenarios.
