摘要
随着电力体系市场化程度不断加深,基于节点电价机制的电力系统输电阻塞规模将不断增大,需要为电网用户提供有效的阻塞管理。以国外的阻塞管理办法为研究基础,结合南方(以广东起步)电力市场的交易结构和市场阻塞盈余分配现状,分析了目前阻塞盈余分摊方法存在的问题,提出了适合南方(以广东起步)电力现货市场环境下的阻塞收益权分配机制设计,并对该设计进行了算例分析。算例模仿了电网用户从申请、分配到结算的阻塞收益权分配全流程,对该机制的有效性进行了验证,确保了阻塞盈余公平、公正、合理返还给用户。
With the deepening of the marketization of power system,the scale of transmission congestion of power system which is based on the nodal price mechanism will increase continuously,and it is necessary to provide an effective congestion management method for power network users.In this paper,under the study of the congestion management method abroad and the trading structure as well as market congestion revenue distribution method of southern China(starting from Guangdong provcince)electricity market,the existing problems of the current congestion revenue allocation method are pointed out,and a design of congestion revenue right allocation mechanism that adapts to the Guangdong electricity spot market is put forward.Additionally,an example is used to simulate the full process of the congestion revenue right allocation including nomination,allocation and settlement in order to verify the effectiveness of the mechanism,which ensures that the congestion revenue is returned to load in a fair,just and reasonable manner.
