摘要
Abstract
For improving the efficiency on power generation of photovoltaic(PV) device,a variable perturb step method was proposed which uses the absolute value of P-U characteristic curve′s points slope of PV device output to determine the variable perturb step and can enhance the search speed and stability at the same time. The Matlab simulation results show that this method can be effective to adjust PV output power in real time. It can greatly improve the tracking speed and reduce the oscillation around the maximum power point (MPP) to lower the engery lost of PV device. This system is simple and easy to promote and use.关键词
