为了保证系统在事故情况下电能可以顺利传送到备用需求区域,备用资源需要均匀合理地分布于电网中。文中建立了一种考虑分区备用的主能量—备用联合市场均衡模型。该模型同时计及网络约束、系统备用约束和分区备用约束,其中区域备用需求可以由本地发电资源和相应区域联络线的剩余传输容量共同提供。此外,还分析了主能量价格、备用价格及两者之间的耦合关系。仿真结果表明,分区备用会导致备用稀缺区域内主能量和备用价格的提高,而系统总负荷收益却会相应减少;此外,在寡头市场环境下,与大部分发电商通过持留容量方式来获取更高收益不同,处于备用稀缺区域内的发电商往往需要通过增加其自身出力来获取更大的收益。
In order to ensure that the system can successfully deliver the power to the standby demand area in the event of an accident, the backup resources need to be uniformly and reasonably distributed in the power grid. In this paper, we establish a main energy-reserve joint market equilibrium model considering partition standby. The model considers both network constraints, system backup constraints and partition backup constraints, where the regional standby demand can be jointly provided by the local generation resources and the remaining transmission capacity of the corresponding regional tie line. In addition, the main energy price, reserve price and the coupling relationship between the two are analyzed. The simulation results show that the partition standby will lead to the increase of main energy and reserve price in the spare scarce area, but the total system load will be reduced accordingly. In addition, with the oligopolistic market, most power producers obtain more Unlike high-yielding, generators in scarce, scarce areas often need to reap greater benefits by increasing their own output.
