The invention discloses a wind and light storage power coordination control system and method, and the system comprises a signal collection unit, an active instruction tracking control unit, an active power smooth output control unit, a voltage reactive automatic control unit, an energy storage management unit, a wave recording unit, and a communication unit. The control unit is respectively used for wind and light storage power station data acquisition, active instruction tracking control, active power smooth output control, voltage reactive power automatic control unit, energy storage management, wave recording and communication. According to the invention, through coordinated control of wind, light and storage active power output, functions of active instruction tracking, active power smoothing and the like are realized, friendly grid connection of a large-scale new energy power station is realized, grid connection safety is guaranteed, wind and light abandoning is avoided, and the method is suitable for grid connection active control application occasions of wind and light storage combined power stations of various scales.
Description
technical field [0001] The invention belongs to the technical field of electric power system control, and relates to a wind-solar-storage power coordinated control system and method. Background technique [0002] After the dual carbon target was put forward, new energy power generation represented by wind power and photovoltaics ushered in a period of rapid development, and the proportion of new energy power generation increased rapidly. However, affected by the fluctuating characteristics of the output of new energy power stations, large-scale new energy power stations connected to the grid will have an impact on grid dispatching and security. It is difficult to pass the grid connection review during the development stage, and problems such as abandoning wind and light will occur after completion. There is an urgent need to develop wind and storage Integrated technology solves problems such as project development, grid connection security, and wind and solar abandonment. ...
