Hybrid wind-solar system - an optimised approach for efficient power generation

The most popular renewable energy technology is hybrid power system consisting of wind and solar energy sources because the system is reliable and complimentary in nature. Wind/PV hybrid system is commonly used in distributed generation (DG). This paper proposes a new solution for improved voltage stability with quality power output. In this system voltage out from wind energy conversion system (WECS) and photo voltaic panel are given to separate DC-DC converters, independently controlled and connected to a common DC bus and from there it is inverted. In the proposed controller the voltage stability is obtained by applying honey bee (HB) optimisation algorithm along with a PI controller. The implementation of the proposed method is done by using Simulink platform. The performance of the suggested coordinated control system is analysed by comparing the computer simulation results with and with out using controllers and it shows that the proposed system is more efficient.
