    摘要:

    随着电力市场的逐步放开,省外低价电的注入给受端电网购电决策带来了巨大的挑战。为此,对计划、市场不同购电渠道的购电成本进行分类和梳理,分析跨省区购电所需遵循的一系列约束,提出计划-市场协调的跨省跨区月度交易决策框架,并建立省级受端电网跨省跨区月度购电决策模型。以总购电成本最小为目标,考虑省内潮流安全约束、特高压直流联络线约束以及省间传输通道约束。以湖南电网为例,探讨计划—市场协调环境下跨省区购电约束对省级电网购电结果的影响,验证所提模型的有效性。

    Abstract:

    With the gradual opening up of the power market, the injection of outside lowprice electricity brings great challenges to the power purchase decision of receiving object. On the background, this paper classifies and sorts out the purchasing cost of different purchasing channels in the electricity plan and market, and then analyzes a series of constraints which needs to be considered in the acrossprovinces /and acrossregions power purchasing. Thus, a monthly trading decisionmaking framework is put forward for the electricity plan and market coordination with the acrossprovinces /and acrossregions trading. In addition, for the purpose of minimizing the total power purchase cost, the power flow safety constraints, on the ultra high voltage direct current (UHVDC) tie line and interprovincial transmission channel constraint are considered. Finally, the Hunan power grid is taken as an example. The influence of crossprovince and crossregion power purchase constraints on the power purchase results is discussed to verify the effectiveness of the proposed model.
