摘　　要：在建设新型电力系统、极端天气频发、一次能源价格飙涨、保供电常态化等背景下,文中提出了基于边际成本比较型竞价模式的电力现货市场机制,为统筹多市场主体利益、协调省间与省内交易提供了可行思路。首先,深度解析了现有电力现货市场机制在统筹多市场主体利益上面临的挑战,在采用边际成本比较型竞价模式的基础上,深入考虑不同类型发电机组的成本特性,提出了一种两阶段分层边际定价的电力现货市场机制,可有效统筹发电侧成本的可疏导性、用电侧电费的可负担性以及新能源机组的激励性。然后,提出了基于边际成本比较型竞价模式的省间-省内两级现货市场机制,并对其应用价值进行了探讨。最后,基于电力现货市场仿真平台开展算例分析,对所提市场机制的有效性和可行性进行了验证。On the background of the construction of the new power system,frequent extreme weather,soaring primary energy prices,and the normalization of power supply emergency,this paper proposes a electricity spot market mechanism based on the marginal cost comparison bidding mode,which provides a feasible idea for coordinating the interests of multiple market players and coordinating inter-provincial and intra-provincial transactions.Firstly,the challenges faced by the existing electricity spot market mechanism in coordinating the interests of multiple market players are deeply analyzed.Based on the marginal cost comparison bidding mode,the cost characteristics of different types of generator units are deeply considered,and a two-stage electricity spot market mechanism for hierarchical marginal pricing is proposed,which can effectively coordinate the guidability of the cost of the power generation side,the affordability of the electricity fee of the power consumption side,and the incentive of the renewable energy units.Then,a two-stage inter-provincial intra-provincial spot market mechanism based on the marginal cost comparison bidding mode is proposed,and its application value is discussed.Finally,a case analysis is carried out based on the simulation platform of the electricity spot market,and the effectiveness and feasibility of the proposed market mechanism are verified.
