摘　　要：针对当前发电权交易未充分利用自备电厂调峰潜力、中长期双边置换限制交易规模且易产生偏差问题,提出风电、光伏、水电及自备电厂、关停火电参与的发电权多边多时间尺度交易模式及电量优化方法。为评估各主体置换优先级,基于交易原则构建交易主体评估指标;采用标度扩展法和信息熵法确定各指标主客观权重,基于最小鉴别信息对组合权重赋值;使用相对熵改进理想解法对交易主体进行综合评估;并基于评估结果提出考虑清洁能源消纳的周、日前、日内多时间尺度发电权置换模式及组织流程;建立以绩效最优为目标的发电权置换电量优化模型。最后,通过算例验证交易主体评估方法、多时间尺度置换模式及电量优化方法的合理性和有效性,可为发电权多边交易提供参考。Aiming at the problems that the peaking capability of self-provided power plant is not fully used in current power generation right transaction,and mid-to-long-term bilateral swap scale is limited which is easy to produce the deviations,this paper proposes a multilateral and multi-time scale generation right trading mode and electricity optimization method with the participation of wind power,photovoltaics, hydropower,self-provided power plant and shutdown thermal power. To evaluate the transaction priorities of each subject,the evaluation indexes are constructed based on the transaction principle,the subjective and objective weights of each index are determined by scale extension and information entropy methods. In addition, the combination weights are assigned based on the minimum information discrimination. And the transaction subjects are evaluated with the improved TOPSIS using relative entropy.Moreover,the multi-time scale replacement model and organization process which include week,day-ahead and day that considering clean energy consumption are proposed based on the evaluation results. Furthermore,the optimization model of generation right replacement is established with the objective of the optimal performance. Finally,an example is given to verify the rationality and effectiveness of the subject evaluation method,the multi-time scale replacement model and the electricity optimization method,which can provide reference for multilateral transactions of generation rights.
