摘要
现货市场是电力市场体系的重要环节,是协调市场交易与系统安全的关键所在。本文对两种现货市场模式——增量优化模式和全电量优化模式进行了研究,分析两种模式在电网约束的处理、交易交割方式和优先级以及优化效果上的差异。通过算例分析了增量优化和全电量优化在调度结果和系统总发电成本上的异同。对国际上典型的现货市场出清模式,包括英国的Bid/Offer为基础的平衡市场机制和美国的含自计划的全电量优化模式进行了对比分析。最后,结合两种模式的特点,对我国电力现货市场的发展建设提出了建议。
As an indispensable part of the electricity market architecture,the spot market is the key to the coordination of market transaction and system operation security.In this paper,two major models,the incremental optimization and integrated optimization model,are studied.The differences between the two models in the treatment of power grid constraints,transaction delivery mode,the priority level and optimization result are analyzed.Examples are presented to illustrate the differences of dispatching result and total generation cost with incremental optimization and integrated power optimization.For the typical international clearing mode of spot market,including the Bid/Offer based balanced market mechnism of the UK and the intergated power optimization mode of USA,comparisons are conducted.Finally,based on the comparison of incremental and integrated optimization,the paper puts forward suggestions for the development and construction of China s power spot market.
