An Overview to the Concept of Smart Coupling and Battery Management for Grid Connected Photovoltaic Battery System

摘要

The paper gives an overview on the need for smart coupling for battery management in grid integrated renewable energy system(RES).Grid integrated photovoltaic(PV) battery system,as being popular and extensively used has been discussed in the paper.Smart coupling refers to intelligent grid integration such that it can foresee local network conditions and issue battery power flow management strategy accordingly to shave the peak PV and peak load.Therefore,a need for predictive energy management arises for smart integration to the grid and supervision of the power flow in accordance to the grid conditions.This is also a running project at the Institute of Energy Systems(INES),Offenburg University of Applied Science,Germany since January,2015.The paper should provide insights to the motivation,need and gives an outlook to the features of desired predictive energy management system(PEMS).
