摘　　要：在电力市场环境下,用户负荷对价格的响应具有跨时段的特性。在计及输电约束的基础上,建立了一个考虑跨时段负荷响应的电力市场多时段线性供应函数均衡模型。该均衡问题是一个具有均衡约束的均衡问题(EPEC),可采用非线性互补方法求解。给出的算例证明了模型的合理性,表明跨时段负荷响应的引入可以缓解由于输电阻塞造成的用电不合理分配,并且能有效抑制发电商的市场力滥用。Under electricity market environment, there is typically a cross-time feature in customers＇ load demand response to prices. A multi-period linear supply function equilibrium model of electricity markets is proposed, with cross-time load demand response and transmission constraints included. This equilibrium model can be categorized as an EPEC （equilibrium problems with equilibrium constraints） problem and be solved by a nonlinear complementarity method. Numerical examples are presented to validate the reasonable- ness of the model. It is also shown that with cross-time load demand response, the unreasonable allocation of loads caused by transmission congestion can be relieved, and the market power abuse of generators can be effectively mitigated.
