Abstract

The invention proposes an energy management control method and control system for a wind power storage system. Through the collection of data of a wind-storage combined power generation system, the charging and discharging states of an energy storage system are controlled by a wind power grid-connected energy storage system energy management control method, therefore, the grid-connected wind poweris regulated, a time period that does not need to be adjusted can be effectively avoided, the energy storage system is efficiently used, relatively good power characteristics and economical efficiency are obtained, the wind power grid-connected electric energy quality is improved, and the quick power response ability and the bidirectional regulation of power in the energy storage system are achieved. The charge and discharge power of the energy storage system is controlled according to the fluctuation of wind power and an energy storage speed, the excessive use of the energy storage system isavoided, the fluctuation of wind power is effectively stabilized, and the voltage quality of the wind power system is improved.

Description

technical field [0001] The present disclosure relates to the technical field related to energy storage systems, and in particular, relates to an energy management control method and control system of a wind power energy storage system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the rapid growth of wind power installed capacity, at least eight 10-million-kilowatt wind power bases have been formed across the country. The strong fluctuation and uncertainty of wind power make large-scale wind power collection areas present typical characteristics of high wind power penetration and weak local power grids. . Similar to distributed photovoltaic grid-connection, in the case of high-penetration wind power access, changes in wind power will cause a surge or sudden drop in grid voltage, which will cause a series of voltage quality proble...
