Abstract:With the rapid development of new energy, a variety of clean energy complementary power generation plays an important role in the power system.This paper presents a multi-energy complementary method considering multi-index comprehensive evaluation. According to the grey prediction model and Weibull distribution model, the power prediction of photovoltaic power generation and wind power generation is carried out, and different types of multi-energy complementary schemes are designed. Different index of energy load curve, economic index of energy combination and stability index are established respectively, and a comprehensive evaluation method considering the influence of multiple factors is proposed. The results of the calculation example verify the effectiveness of the proposed multi-index evaluation method in the selection of clean energy complementary schemes.
