Optimal design and sensitive analysis of distributed generation system with renewable energy sources

In the case of ensuring the reliability of power supply, in order to improve the economy of the distributed generation systems, it should be based on different resource conditions to optimize the design of the system. This paper constructs the distributed power generation system structure of multiple distributed power supply. The main factors affecting the optimal design are discussed qualitatively. The minimum net present cost (NPC) is the optimization goal. The system was optimized by using Homer software, the optimal design scheme of distributed generation system is given in this paper. In addition, according to the natural resources, load level and fuel price, this article carries on the sensitive analysis of the distributed generation system. The influence of these factors on the optimal design of the distributed generation system is studied. When the values of these important factors change, this paper gives the variation of optimal scheme for the distributed generation system. It provides a reference to the project planning and installation of the distributed generation system.
