Abstract :
Due to the unreasonable reactive power configuration for wind power base, disconnection of large-scale wind turbines from grid has caused several times in the world recently. Based on the brief analysis of the process of the accident in wind power base, risk is introduced to make reactive power configuration for wind power base in this paper, considering the cost of investment of reactive power compensation, active power reserve and load shedding. The risk is optimized to be minimized by coordinating adjustable active power reserve, interruptible load and so on. Then the reactive power configuration scheme can be obtained by genetic algorithm. By comparison the proposed method with the traditional methods using the data of an actual grid with wind power in domestic, from the point of the view from economy, stable voltage at PCC and the performance of transient voltage, it shows that the reactive power configuration obtained by the proposed method is better.
