The Design of a Grid-connected Photovoltaic Power Conditioning System

Abstract

In view of the grid-connected photovoltaic power system’s function of load shifting to the power network and to achieve the coordinated control of inverter and battery management system, this paper designed a grid-connected photovoltaic power conditioning system (PCS) with function of bi-directional conversion. The function of the PCS is set, the control strategy and technology indexes is also given out. The research improves the solar energy utilization efficiency of the grid photovoltaic power generation, and makes the function of load shifting to the power network coming true without interference, so as to achieve the purpose of saving energy.
