The Effects of Residential Battery Storage on Grid Impact Indicators

Grid impact indicators hold valuable information about a prosumer when interpreted carefully. This makes them quite useful for benchmarking different demand side management schemes and studying active buildings. In this paper, the effects that battery storage has on five such indicators have been addressed in detail. Their values were calculated by analyzing 20 households with photovoltaics (PVs) for a period of one year. Measurement data of the households electricity consumption and PV generation were obtained from a publicly available database. To improve the scope of the analyses, three battery control strategies have been used to simulate the battery's operation. The findings show that four of the five analyzed indicators follow certain patters when plotted as a function of the prosumer's generation-to-consumption ratio. Similar patterns are also observed in the absolute changes in the value of all indicators when storage is integrated.
