Hybird Energy Storage System Optimal Configuration Based on Smooth Control Strategy
According to the tie line fluctuation due to the connection of distributed generation with stochastic characteristics
adding hybrid energy storage in microgrid can effectively restrain this fluctuation
improve power quality. Using battery-super capacitor hybrid energy storage
the hybrid energy storage system output is determined by second-order low-pass filter method
and this output is fixed by advance control strategy considering the residual capacity of the super capacitor
improving the life of super capacitor while almost no effect on battery. An economic evaluation model considering yearly minimum cost of hybrid energy storage capacity configuration is established.The effectiveness of the proposed method is verified by simulation results.
