In view of the present problem in low efficiency of the wind-light complementary power generation system, the tracking control strategy on the system maximum power point was proposed based on the perturbation and observation method, and overall structure of wind-light complementary power generation system is introduced. The simulation study on the system maximum power control was carried out based on the MATLAB/ SIMULINK, and the results of simulation showed that the tracking control of the system maximum power point was able to be achieved and the utilization efficiency of the system energy was also improved.

For the intermittent nature of renewable resources (such as wind and solar), smooth power fluctuations are required before the energy conversion system can be injected into the grid. The battery system is a typical smoothing control method for photovoltaic power. The long-term overcharge and overdischarge make the battery energy storage scheme unattractive. In this paper, the output power fluctuation of the photovoltaic power generation system is smoothed based on the unscented Kalman filter (UKF) method combined with the fuel cell operating characteristics. This coordination method affects the UKF situation through the feedback of state of charge (SOC) and the power of the battery system. Not only can it better meet the load characteristics, but it can also make the SOC automatically correct the battery system to prevent overcharge and overdischarge. The meteorological load data was used to verify the superiority of the method.

Photovoltaic cells power generations are increased, because of lack of electrical power. Using of uniform solar irradiation in the photovoltaic cells, power-voltage characteristics must be unique and the maximum power is generated from PV cells. The MPPT Device is an essential part for photovoltaic power generation system. Because of nonlinearity behavior of irradiation and temperature in atmosphere.
