摘要：

Due to the intermittency and volatility of wind power output, the traditional operation mode of power grids and the adjustment capability of conventional units were unable to meet the growing demands of large-scale wind power integration. The reduced probabilistic scenario set was used to describe the uncertainty of day-ahead wind power output, and the day-ahead unit commitment schedule for handling wind power fluctuation could be derived. In allusion to the restricted influence by the adjustment capability of units on wind power absorption, we proposed a coordination operation mode of high energy load and conventional units. On this basis, we established a multi-time scale source-load coordination dispatch model to minimize the total operation cost and the pollution emission, which considered a day-ahead dispatch, an intra-day rolling dispatch and a real-time dispatch in harmonious cooperation, and adopted the intelligent optimization algorithm to solve it step by step. The actual example verifies the rationality and practicality of the proposed model, which can provide an effective approach for intermittent energy absorption in power grids. © 2019, High Voltage Engineering Editorial Department of CEPRI.
