摘要/Abstract

摘要： 现货市场出清结果需通过N–1安全校核和交流可行性校验之后下发至机组，现有方法下校核与定价剥离，导致市场出清解和运行点的偏离并产生上抬费用。为解决该问题，研究考虑交流可行性校验的现货市场全环节建模及修正策略。首先，建立考虑调峰需求的调度模型并基于KKT条件证明了节点电价可以满足储能设备和传统机组的激励相容性质；然后，建立基于交流潮流的可行性恢复模型，将交流可行性恢复成本内嵌到出清及定价模型中；最后，针对可行性校验越限场景，提出满足不同市场出清时间窗要求的场内、场外越限修正策略。算例表明，所提方法能有效恢复交流可行性，当越限需新增机组进行调整时，无时限要求下场内修正最具优势，有出清时限要求下基于凸松弛的场外修正策略比基于功率转移分布因子的修正策略运行成本和市场盈余更小。

Abstract: The market clearing results of spot market need to be delivered to the generators after passing N-1 security contingency analysis and AC feasibility check. In existing methods, the check procedures are split from pricing model, which leads to the deviation between the market results and the practical operation instructions and incurs uplift payment. To resolve this problem, a study is made on the full-process modeling and correction strategies in spot market. Firstly, a dispatching model with consideration of the power peak shaving requirement is formulated, and it is proved based on the KKT condition that the LMPs can guarantee storage devices’ and traditional generators’ incentive compatibility. Then, an AC power flow based feasibility restoration model is established, which incorporates the restoration cost into the dispatching and pricing model. Finally, under the circumstances of violations, the strategies for market correction and out-of-market correction are proposed to meet different requirements of market clearing time. It is verified with case study that the proposed method can effectively restore the AC feasibility. When there is no time restriction, the market correction method has advantages over other methods. When there is a time restriction, the convex relaxation based out-of market correction method obtains less operation cost and market surplus than the PTDF-based correction method.

Key words: market clearing, power peak shaving, incentive compatibility, AC feasibility check, out-of-market correction
