Solar energy and wind energy are the two most viable renewable energy resources in the world. This paper presents a control strategy for wind & solar hybrid power generating systems. If the power generation sources produce more energy than the one required by the loads, the surplus energy can be used either to charge the battery or to provide a dump load (electric heater or electrolysis-hydrogen). If the amount of energy demanded by the loads is higher than the one produced by the power generation sources, the control strategy determines the battery will release energy to cover the load requirements until the battery is fully discharged. This paper explains the scheme developed and shows the control flowchart of hybrid power generation system.

A new type of photovoltaic grid power generation system control scheme to solve the problems of the conventional photovoltaic grid power generation systems is presented. To aim at the oscillation and misjudgment of traditional perturbation observation method, an improved perturbation observation method comparing to the next moment power is proposed, combining with BOOST step-up circuit to realize the maximum power tracking. To counter the harmonic pollution problem in photovoltaic grid power generation system, the deadbeat control scheme in fundamental wave synchronous frequency rotating coordinate system of power grid is presented. A parameter optimization scheme based on positive feedback of active frequency shift island detection to solve the problems like the nondetection zone due to the import of disturbance in traditional island detection method is proposed. Finally, the results in simulation environment by MATLAB/Simulink simulation and experiment environment verify the validity and superiority of the proposed scheme.
