电力市场可中断负荷合同模型研究

可中断负荷管理是电力市场环境下需求侧管理的重要组成部分，与电力系统安全经济运行密切相关。该文讨论了可中断负荷合同的内容和相关市场组织形式：利用停运表得到考虑负荷波动情况下的系统缺额容量以及采用需求侧报价来反映用户可接受的停电补偿。给出可中断负荷的最优购买模型，模型以购买费用最小作为目标函数，包括停电持续时间和停电总次数等约束。参照机组检修的思路，给出安排可中断负荷的基本原则并采用相应算法求解。实际系统算例表明该模型的有效性。

STUDY ON MODEL OF INTERRUPTIBLE LOAD CONTRACT IN POWER MARKET

Interruptible load management (ILM) is an important part of Demand Side Management (DSM) in power market. This paper discusses the contents and implementation processes of the interruptible load contract. Demand side bidding (DSB) is utilized to embody the compensation cost for the large users. Considering the load fluctuation, we use the capacity outage table to obtain the expectation value of power not served. Then the paper presents the optimal purchase model of interruptible load. Similar to the maintenance schedule method, a merit order method is employed to solve the problem. Case studies for a real power system demonstrate usefulness of the proposed model.
