Techno-economic analysis of HES and CES using MRFO technique

Power demand has increased notably from past few years globally. But, it is very important to preserve our conventional energy sources and also reduce the emission of greenhouse gases along with it. This has made the usage of Decentralized energy resources (DERs) popular. However, the operation of DERs is intermittent that results into grid instability and discontinuity of the supply. Also, due to the usage of DERs electricity cost are higher unnecessarily. So, in order to reduce these costs Energy Storage Systems(ESSs) can be used. ESSs store surplus energy temporarily and use it later as a supply source according to the power demand. Household energy storage (HES) and Community energy storage (CES) are the suitable ESSs for such cases. HES is generally installed in each household which consists of a smaller sized battery pack that stores electricity from the microgrid as well as the utility. Whereas a CES is connected to a number of households at a time. CES has a larger sized battery pack which has certain shares for each household. The aim of this paper is comparison of economic performance of HES as well as CES systems. For that purpose, a mathematical optimization tool named Manta ray foraging optimization(MRFO) is used in both the scenarios.
