Abstract
ABSTRACT:Random fluctuation of power output and multiple reactive power devices are typical characteristics of large-scale wind farm. In allusion to reactive power and voltage issue it causes, probabilistic optimal reactive power dispatch model is built and a solving method using unscented transformation and adaptive focus particle swarm optimization is proposed. In the model, power uncertainty of wind farm and load are solved with unscented transformation based probabilistic power flow, and switched capacity of dynamic reactive power device is added into objective function to coordinate dispatch of static and dynamic reactive power devices. Simulation result confirms that the model proposed can dispatch multiple reactive power devices in coordination. In comparison with Monte Carlo simulation method and traditional optimal reactive power dispatch method, the solution proposed in this paper is not only efficient in handling influences of uncertain power variables, but also adaptable to schemes for different wind power output states.关键词
