摘要
【目的】为了保证拍卖收益权的分配结果在实际电网中具有物理可执行性,拍卖收益权的分配结果需要满足可行性测试。传统的基于灵敏度因子的可行性校验算法使得拍卖收益权的分配结果依赖于线路的次序,从而影响削减结果的公平性。为此,提出了一种内嵌可行性测试的拍卖收益权分配方法。【方法】首先,提出拍卖收益权的分配原则和申报方式,保障参与者的基本用电权益。然后,提出一种内嵌可行性测试的拍卖收益权分配算法。该算法以最小化用户总申请容量的削减量为目标,考虑线路潮流约束,建立拍卖收益权分配模型并求解。最后,基于IEEE 5节点系统,将所提算法与采用传统可行性校验的分配算法进行对比。【结果】结果表明,所提方法相比传统方法在节点边际电价(locational marginal pricing,LMP)机制下总削减量减少可达25.0%,线路利用率提高可达7.2个百分点;在负荷侧统一电价机制下总削减量减少了20.9%,线路利用率提高了9.2个百分点。【结论】所提方法可以提升拍卖收益权分配的公平性,降低总削减量,提高线路利用率。
[Objective]In ensuring the physical feasibility of auction revenue right(ARR)allocation in actual power grids,feasibility tests must be satisfied.Traditional post-feasibility verification algorithms based on sensitivity factors make ARR allocation results dependent on line sequences,which affects the fairness of the results.This study proposes an ARR allocation method with embedded feasibility testing.[Methods]First,ARR allocation principles and application methods are proposed to safeguard the basic electricity rights of the participants.Subsequently,an ARR allocation algorithm with embedded feasibility testing is developed.This algorithm aims to minimize the total reduction in the users'requested capacity while considering line-flow constraints,by establishing and solving an ARR allocation model.Finally,based on the IEEE 5-bus system,the proposed algorithm is compared with the traditional post-feasibility verification allocation algorithm.[Results]Compared with traditional methods,the proposed method decreased total capacity reduction by up to 25.0%and increased line utilization rate by up to 7.2%under the locational marginal pricing(LMP)mechanism.Under the load-side uniform pricing mechanism,total capacity reduction decreased by 20.9%and line utilization rate increased by 9.2%.[Conclusions]The results show that the proposed method improves the fairness of ARR allocation,decreases total capacity reduction,and increases line utilization rate.
