Active power dispatch and regulation of wind power system based on electrical dissecting information of electric power network

Randomicity and intermittence of wind speed make power system dispatch become difficulty. The paper presents a two-layer strategy for wind power system dispatch and regulation. The strategy can revise pre-dispatch scheme for traditional generators in online dispatch time scale and trace the fluctuation of real-time power output by regulating the AGC (automation generation control) generators related to wind generators in AGC time scale. By the electrical dissecting information of paths among wind generators, related traditional generators and their loads, adjusting factors for revising traditional generating scheme and load distribution factors for regulating the AGC generators related to wind generators can be computed. Example shows the strategy can effectively trace the fluctuations or forecasting errors of wind and load power, and enhance the operation quality of entire power system.
