Energy Storage Control Based on Wind Farm

Abstract:

With the increase in wind power generation and network capacity, Wind farm power fluctuations on the grid greatly. In order to improve the operational stability of wind farm grid, at its outlet to increase the energy storage system for the new environmentally friendly vanadium redox flow battery (VRB) to effectively regulate the grid power. According to the VRB equivalent mathematical model using a bidirectional DC/AC converter as VRB storage system power regulator, the corresponding charge discharge control and energy management strategy are designed , and grid-connected wind farm system with VRB energy storage unit are modeled and simulated. Simulation results show that the fluctuations in wind speed Circumstances, the VRB energy storage system can quickly and effectively smooth the fluctuations of the active power of the wind farm output, and can provide reactive support to the grid, effectively improve the operating performance of wind farm.
