Modeling and Simulation of Grid-connected Hybrid Photovoltaic/Battery Distributed Generation System
Photovoltaic（PV）generation is the technique which uses photovoltaic cell to convert solar energy to electric energy. Nowadays,PV generation is developing increasingly fast as a renewable energy source. However,the disadvantage is that PV generation is intermittent for depending on weather conditions. Thus,the battery energy storage is necessary to help get a stable and reliable output from PV generation system for loads and improve both steady and dynamic behaviors of the whole generation system. The paper presents detailed transient models of the grid-connected PV/Battery hybrid generation system,and all these models are simulated by using MATLAB/Simulink. PV array is firstly connected to the common dc bus by a boost converter,where the battery is also connected by a bi-directional DC/DCconverter,and then integrated into the ac utility grid by a common DC/AC inverter. Maximum power point tracking helps PV array to generate the maximum power to the grid,and the battery energy storage can be charged and discharge to balance the power between PV generation and utility grid. Finally,different cases are imulated,and the results have verified the validity of models and control schemes.
