摘要:
宁夏电网考虑大用户直购电约束的中长期调度计划优化研究与应用在优化模式上兼顾了节能发电调度、经济调度、兼顾节能的经济调度等模式，在时间维度上跨越了年度、季度、月度、周、日前等多个时间维度，立足于电力系统基础理论和数学优化理论，充分考虑实际调度经验和实际运行中的实际需求，以及大用户直购电交易约束，采用先进的设计思想，并对应研究开发相应的关键性技术和模型，全面实现年度电量分解、机组组合制定、年度电量分解与机组组合相协调的中长期调度计划一体优化决策，从调度计划的制定精度、制定效率、计划结果合理性等多个方面全面提升调度计划的质量。
This paper takes account of the mode of energy generation dispatch, economic dispatch and energy conservation dispatch which has been across multiple time dimensions including year, quarter, month, week and day. This paper is based on power system basic theory and mathematical opti-mization theory. It utilizes advanced design ideas to develop key technologies and models which take adequate account of actual scheduling experiences, actual needs in operation and trading constraints of direct power purchase of large consumers and also implement long-term scheduling optimization decisions on annual electricity decomposition, unit combination formulation and the coordination of them. The research improves the quality of scheduling in many methods like the precision and efficiency of scheduling, and the rationality of scheduling results.
