Three-Phase Grid Connected Solar Powered Battery- Super Capacitor Based Hybrid Energy Storage System

Abstract

The power generation from renewable power sources is variable in nature, and may contain unacceptable fluctuations, alleviated by using energy storage technique. The cost of batteries and their limited lifetime are serious disadvantages. Solve these problems; improvement consisting in the collaborative association of super capacitors and batteries has been studied. The Super capacitor-Battery based hybrid energy storage systems are a popular choice for the battery lifetime extension and system power enhancement. The Battery ESS is characterized by high energy density, low power density, degradation due to frequent and partial charge/discharge cycles. By incorporating SC ESS which has high charge/discharge rates, a system having both high energy and power capabilities can be designed.  The proposed scheme is validated by detailed simulation and experimental results.
