Research on optimization of wind and PV hybrid power systems

To effectively and reliably utilize renewable resources then achieve the wind/PV (photovoltaic) hybrid generator, a new type wind/PV hybrid generator was designed, which adopts the auto-interference controller designed by utilizing the nonlinear transform of aerodynamic force to capture wind to the highest degree, and also other technologies as brushless double-fed wind generator, extremum control on solar inverter. Considering the multi-input and multi-output of the distributed hybrid power system, using the theory of linear relationship between the hierarchical fuzzy controller’s totalities and variables, here give the hierarchical fuzzy controller Algorithm to control the loading and unloading of wind generators, solar cells and the grid. The experiments show that: on the premise of utilizing renewable resources to the greatest extent, system can realize the equilibrium between the supply and demand of the electric energy automatically according to its load.
