The method of using energy about a large number of industrial enterprises lock economy. Firstly, built the operation cost model of using energy made industrial enterprise as object, also established the comprehensive optimization model contain wind-PV-ES hybrid micro-grid considering industrial energy efficiency and improved adaptive genetic optimization algorithm is programmed based on MATLAB7.0. Then a wind-PV-ES hybrid micro-grid as a studied object, we optimize the industrial enterprises behavior about purchase power energy in 5 typical scenarios and obtain the best power purchase scheme. The results show that reasonable use wind-PV-ES hybrid micro-grid it not only improve economy but also reduce operation cost about industrial enterprises.
