面向社会福利最大化的跨价区中长期净可用传输能力计算模型
Calculation Model of Cross-zonal Medium-and Long-term Net Available Transfer Capability for Maximizing Social Welfare
摘要
Abstract
A calculation model of cross-zonal medium-and long-term net available transfer capability(ATC)is proposed to give full play to the optimal allocation of resources in the medium-and long-term electricity market.Before the formal clearing of medium-and long-term transaction,based on the feasible domain of channel-coupled ATC transaction calculated by the ATC of critical branch,a calculation model of cross-zonal medium-and long-term net ATC is established to obtain the upper limit of transmission power for cross-zonal transaction decoupling.This model considers the typical scenarios for generation cost ranking in various price zones,achieving the maximum social welfare while maintaining high overall utilization rates of transmission channels.A comparative analysis is conducted on the social welfare and its deviations of three net ATC calculation models,including the proposed model,the model with the optimization objective of maximizing social welfare in a certain scenario,and the model with the optimization objective of maximizing total ATC.Through the simulation calculation of the modified IEEE 118-bus system,the correctness and effectiveness of the proposed model,as well as the necessity of calculating cross-zonal net ATC before the formal clearing of medium-and long-term transactions are verified.关键词
