Modelling and Control of Wind PV Based Hybrid Power System Considering Hybrid Energy Storage System Incorporating Battery and Supercapacitor

In this paper a control strategy is proposed for the control of battery supercapacitor based hybrid energy storage system applied to wind PV based hybrid renewable energy system. The hybrid combination of battery supercapacitor provide complement solution for high power and higher energy storage system and thereby covering wide range of applications. The controller is designed based on the variations in the DC link voltage and these variations are suppressed using controller. The proposed controller is tested under two modes of operations surplus power mode and deficit power mode. The power imbalance between supply and demand is minimized using hybrid energy storage system where low frequency components are absorbed by battery and high frequency components are tackeld by supercapacitor. The results show that the proposed control strategy worked satisfactorily for both the case. The results are verified in MATLB Simulink environment.
