摘　　要：提出了基于可中断负荷拍卖模型的电力双边交易阻塞管理方法,通过市场机制来确定最优的负荷削减程序。阻塞调度过程可以分为三个阶段:调度前阶段、无约束调度阶段和考虑可中断负荷拍卖的阻塞调度阶段。在第三阶段,用户可以向调度机构提交各自的可中断负荷服务报价曲线。构建了阻塞调度模型,综合考虑了最小化所中断的负荷量和最小化向用户支付的可中断负荷服务费这两个优化目标。最后用算例对所提出的模型进行了验证。A congestion management framework in bilateral electricity market is proposed based on interruptible load auction model. The optimal load shedding quantity is identified by market mechanism. Under the proposed framework, the procedure of dispatch is divided into three stages： pre-dispatch, unconstrained dispatch and congestion dispatch considering interruptible load auction. The customers can submit their interruptible load bidding curves to ISO at the third stage. The congestion dispatch model considers the objectives of minimization of the interrupted loads and the interruptible load services fee paid to customers. Finally, a numerical example is presented to indicate the feasibility of the model.
