Abstract

This paper proposes a voltage compensator (VC) for a grid-connected photovoltaic generation system to compensate shadowing phenomena. The solar cell array in this paper is composed of several strings using the same maximum power point. The proposed VC is an isolated DC-DC power converter which supplies a voltage to compensate for the voltage of shaded string in order to maintain the output voltages of every strings of a solar cell array to be the same. Therefore, the problem of multi-peaks in P-V curve of solar cell array caused by shadowing in a solar generation system can be solved. Therefore, the power generation in grid-connected photovoltaic generation system can be increased. A solar cell array comprising two strings is tested to verify the performance of the proposed VC. The experimental results are as expected.
