摘要
目前,我国集中竞价模式的发电权交易一般都以撮合定价为结算依据。但在考虑电力系统的网络安全约束时,现有的发电权交易模型难以充分计及撮合定价的相关规则,可能导致最终的结算关系不完全合理,市场的公平性受到影响。针对这一问题,提出了发电权交易的撮合匹配模型,并以此为基础提出一种求解发电权交易的两阶段方法。该方法以现有发电权交易阻塞管理模型的优化解作为初始撮合匹配对,采用所提出的发电权交易撮合匹配模型对初始撮合匹配对进行优化调整,得到符合撮合定价相关规则的最优撮合匹配对。运用IEEE 30节点系统算例对上述方法的有效性进行了验证。
At present, the matching price is taken as the foundation of settlement for generation trades to which the concentrated bidding mode is used. However, when security constraints of power network are taken into account, it is hard for existing generation right trading model to fully consider related rules of matching price, so it may make the final settlement relation totally rational. To solve this problem, a matchmaking model for generation right trade is proposed and on this basis a two-stage method to solve generation right trade is put forward. In the proposed method the optimized solution of existing congestion management model for generation right trade is taken as initial matching pairs; then the proposed matchmaking model for generation right trade is utilized to perform optimization adjustment of the initial matching pairs to obtain optimal matchmaking pairs which conform to related rules of matching price; finally, the effectiveness of the proposed model and method is verified by IEEE 30-bus.
