Abstract

The invention discloses an energy storage-combined wind power plant energy management system, comprising an energy management module, a wind power plant booster station data collecting module which isconnected to the energy management module, an energy storage device data collecting module, a scheduling data receiving module, a wind turbine generator data collecting module, a storage module, a historical data query module, a wind turbine generator system control module, an energy storage device control module, and a monitoring alarm module connected to the storage module. The invention is advantageous in that active and reactive fluctuation of the wind power plant can be inhibited; wind power scheduling can be optimized; the control of reactive power, reactive voltage and power factors ofthe wind power plant can be better completed; the demand of power grid guidance on the grid connected voltage control precision can be met.

Description

technical field [0001] The invention relates to the field of energy management of wind farms, in particular to an energy management system of wind farms with integrated wind storage. Background technique [0002] In the past two years, severe smog has frequently occurred in many places in my country, and "waiting for the wind" has become the most ardent hope of people. This is a kind of joke, but also a kind of helplessness. This reflects that the development mode dominated by fossil energy has exceeded the carrying load of the environment, and the development of clean energy such as wind power, solar energy, and tidal energy has become a strategic choice for the country. With the deepening of the "Thirteenth Five-Year Plan", the goal of wind power development is expected to be further raised. However, contrary to the speed and scale of development, the phenomenon of curtailment of wind power has become more and more prominent, which has become the main bottleneck affectin...
