摘要：

针对我国双轨制下双边电力市场电能电费疏导、不平衡费用分摊等关键问题,利用“日前基准、实时差量、合约差价”双结算体系实现合约市场与现货市场的耦合结算,考虑应承担责任主体构建不平衡资金分摊/返还模型,设计考虑不平衡资金处理的双边现货市场结算机制,并以浙江省电力市场进行仿真分析。算例结果证明了该结算机制的合理性,有效的电费结算体系可以提高发用主体参与电力市场的积极性,为双轨制下双边电力市场结算提供相关参考建议。

Abstract:

Aiming at the key issues such as energy and electricity cost dredging and unbalanced cost allocation in the bilateral power market under the double-track system in China, the dual settlement system of "day-ahead benchmark, real-time difference, and contract price difference" is used to realize the coupling settlement between the contract market and the spot market, and the construction of the responsible entity is considered. The unbalanced capital apportionment/return model and the bilateral spot market settlement mechanism considering the unbalanced capital processing is designed, and the simulation analysis is carried out with the power market of Zhejiang Province. The calculation example proves the rationality of the settlement mechanism. An effective electricity bill settlement system can improve the enthusiasm of the generators to participate in the electricity market, and provide relevant reference suggestions for the settlement of bilateral electricity markets under the double-track system.
