摘要

In recent years, the wind power industry of China has a rapid development. However, because of the uncertainty, randomness and fluctuation nature of wind power, the problem of its integration and accommodation has become the bottleneck of its sustainable development. Cross-regional accommodation has emerged as an attractive and challenging research area due to the fact that wind energy resource is usually far away from load center and hard to be used locally. Thus, a generation-reserve co-optimization dispatch method for wind power integrated power system considering cross-regional accommodation is proposed in this paper. Considering the prediction errors of wind power and load demand and also equipment failures, the reserve requirement for each area is calculated based on the theory of conditional value-at-risk. Further, generating units are scheduled optimally, and the geographical allocation and levels of the required reserves are determined taking into account interregional transmission line constraints. The aim of this paper is to promote the wind power accommodation in a larger spatial scale and also the system efficiency from both the economic and security point of view. The reasonableness and effectiveness of the constructed model is validated by case study.
