The operation of hybrid energy system is influenced not only by the availability of the local energy resources, but also due to the market energy pricings. In this work, a typical institutional hybrid energy system of TERI's Retreat building, India is selected for evaluating the performance by considering Time-of-Use (ToU) tariff, and with and without distributed generator. The considered hybrid system consists of PV, battery and grid connectivity for meeting the institutional load demand. The real-time operation data of one year is used to analyze battery energy throughput with contribution from the distributed generator specially during the grid outage period. It is observed that effective use of ToU energy tariff can significantly improve the local PV utilization and operation of energy storage within the hybrid energy system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
