| Summary: | The purpose of this project is to compare between Energy Storage System(ESS, battery only) and Hybrid Energy Storage System(HESS, battery and supercapacitor) for a stand-alone PV system, followed by designing and simulation of an ESS for institutional building by considering the load demand, temperature and solar irradiance. The advantage of this project is to prolong lifespan of ESS and reduce the fluctuation of the output power and battery current. Parallel-active topology converter are used with underline control circuit using PI controller to maintain the ESS and PV output voltage at constant value even if there is a small reduction in irradiance. By using MATLAB/Simulation a stand-alone PV system with ESS (battery only) and HESS(battery with supercapacitor) are designed and simulated. The comparison results shows that with HESS (battery with supercapacitor), the SOC of battery little improves by 0.0005%, the peak current reduced by 69% and the fluctuations of output power and battery current are reduced compare to ESS(battery alone). |
