Control Strategy of Hybrid Solar-Wind Power Generation

Control strategy of hybrid solar-wind power generation system with integrated converter was proposed in this paper. A novel switched reluctance generator (SRG) converter topology which integrated energy conversion of wind power and solar power are proposed. Traditionally, wind power and solar power have separated energy flow path in the solar-wind system. However, in the proposed SRG system, the exciting current of SRG was used to build the magnetic field, which can be supported from the solar energy. Except the way of excitation, the solar energy can be charged the bus from the idle phase windings of SRG. The hybrid solar-wind power generation system which eliminates the circulating energy of SRG, uses solar energy as excitation energy to optimize the energy conversion path of the system. The energy conversion efficiency of the system is improved. The BP neural network is used to estimate the switch angle of proposed converter to improve the efficiency of system. The experimental results are done to verify the performance of proposed method.
