摘　　要：研究电能量与辅助服务市场电价间的耦合机理,有助于源、荷、储参与电能量和辅助服务市场,并形成较为透明的电能量与辅助服务市场电价机制,促进电能量与辅助服务市场的健康发展。为此,提出了电能量与辅助服务市场联合出清模型与电价耦合机理分析方法。首先,分析了荷、储类市场用户的能量与功率边界特征,建立了各类用户参与电能量与辅助服务市场的耦合约束模型;其次,构建了含源、荷、储参与的电能量与辅助服务市场联合出清模型;再次,基于对偶原理和KKT(Karush-Kuhn-Tucker)条件,提出了电能量与辅助服务市场耦合因子的概念与获取方法,揭示了多元市场间的耦合关系。最后,通过算例分析验证了所提出方法的有效性。Studying the coupling mechanism of electricity prices between the electric power energy and ancillary service markets helps the source,load and storage participate in the electric power energy and ancillary service markets,and form a more transparent price mechanism of electric power energy and ancillary service markets to promote the healthy development of electric power energy and ancillary service markets.Therefore,a joint clearing model for the electric power energy and ancillary service markets and an analysis method for the electricity price coupling mechanism are proposed.Firstly,the energy and power boundary characteristics of load-and storage-type market users are analyzed,and the coupling constraint model for various types of users participating in the electric power energy and ancillary service markets is established.Secondly,the joint clearing model for the electric power energy and four ancillary service markets including the participation of source,load,and storage is constructed.Thirdly,based on the duality theorem and KKT(Karush-Kuhn-Tucker)condition,the concept and the acquisition method of the coupling factor between the electric power energy and ancillary service markets are proposed,and the coupling relationship between the multiple markets is revealed.Finally,the effectiveness of the proposed method is verified by case analysis.
