水火互济电源结构下的市场交易偏差电量处理与结算机制

Processing and settlement mechanism of market transaction deviation of electricity quantity under the structure of water-fire mutual power supply

偏差电量的处理与结算机制是判断交易机制是否公平、合理的重要衡量标准之一,处理与结算机制是否得当将直接影响市场主体之间的经济利益和市场改革的推进程度。在总结国内现行电力市场偏差处理和结算机制的基础上,以水火互济电源结构的广西为例,分析电力市场现行偏差处理、结算机制和存在的问题,设计了基于计划与市场不解耦思路和月度预挂牌2种偏差处理和结算机制,并构建了月度预挂牌机制实施的安全约束机组组合和安全约束经济调度模型。最后,通过对2种偏差处理机制的对比分析后,提出了从基于计划与市场不解耦思路过渡到基于月度预挂牌,最终发展到现货市场机制下市场交易偏差处理和结算机制的分阶段实施建议。

The treatment and settlement mechanism of deviation power is on important standard to judge whether the transaction mechanism is fair and reasonable.Whether the treatment and settlement mechanism is appropriate will directly affect the economic interests between market subjects and the promotion degree of market reform.Based on the summary of the current treatment and settlement mechanism of deviation power in the domestic power market,taking Guangxi as an example,the current deviation treatment,settlement mechanism and existing problems in the power market are dnalyzed,two deviation treatment and settlement mechanisms based on the idea of uncoupling plan and market and monthly pre-listing are designed,and the safety of the implementation of the monthly pre-listing mechanism constrained unit commitment and safety constrained economic scheduling model are corstructed.Finally,through the comparative analysis of the two deviation handling mechanisms,the phased implementation suggestions are put forward from the idea of no decoupling between plan and market to the idea of monthly pre-listing,and to the market transaction deviation handling and settlement mechanism under the spot market mechanism.
