The study of storage energy capacity matching optimal at current mainly focuses on the principle and is lack of practical realization way. The authors

based on the former researches

develop an optimal matching software for wind farm and energy storage integration system based on VC++ platform. Firstly

the typical load data searching module is developed according to the energy storage optimal matching principle and MFC functions. Secondly

the functional module of energy storage capacity optimal matching is developed based on the reasonable expectation of load peak and valley and using GA algorithm and combination with the dialogue function in MFC. Finally

the detection result module for energy storage capacity optimal matching is developed

which is of real time display function. The developed software is used to be tested in a wind farm in Xingjiang and to be compared to the practical operation data in local electrical network. The results show that

based on the energy storage allocation presented in this paper according to this software

it can not only eliminate high fluctuation from wind electricity

but also reduce the risk to the electric network from back peak adjustment. It also has the optimal investment to energy storage system and the advantage of knowing the energy storage situation at any time. It has important reference to improve the energy storage capacity optimal matching.
