Optimization of power dispatching based on correlation analysis for wind farm group

摘要

Based on the correlation analysis of wind power outputs, this paper proposes the optimal scheduling scheme for wind farm group outputs which are limited by grid. By considering the predictive ability and the mutual influence among wind farms, an optimal model for threshold power distribution is established, which takes the minimum power loss of involved wind farm group as target. And it is solved by a mathematical programming method. Results show that by contrast the optimal scheme in this paper can reduce about 0.27% of the abandoned wind power, it's also more conducive to attenuate the volatility, which helps improve the utilization and the quality of wind farm group outputs. At the same time, the effectiveness and feasibility of the scheduling scheme is also verified.
