摘要
发电权撮合交易中常常通过取消或削减发电商的交易来满足系统的安全约束,这将给发电商带来损失,如何体现发电商的交易需求、降低发电商的交易风险是发电权交易研究的一个重要课题。借鉴金融输电权规避市场风险的思想,将一种新型金融输电权引入发电权撮合交易模型,以规避因阻塞使得发电商计划交易量不能完成的风险。根据模型特点采用遗传算法求解,不但可以保证撮合结果的最优性,而且算法可以体现出金融输电权对交易调度的指向作用,激励发电权交易双方合理报价,确保市场交易公平性。并探讨了该模型下的发电权交易结算方案和实施步骤。采用IEEE39节点系统对提出的方法进行了验证。
In generation rights trade,some transactions have to be cut or canceled to meet the system security constraint,which will bring losses to the generation companies.How to reflect the trade demand of generation companies and reduce the trade risks is an important subject in research of generation rights trade.In electricity market,financial transmission right is an effective tool for avoiding market risks.This paper,based on the characteristics of generation rights trade,introduces a new financial transmission right to the generation right matchmaking model.In this model,the traders who purchase transmission rights will enjoy the priority right to trade and gain the compensation when the trades are cut or canceled.The calculation by Genetic Algorithm not only guarantees the optimality of solutions,but also materializes the effect of transmission right on the generation rights trade,restrains the speculation and guarantees the fair trade.Furthermore,the settlement scheme and implementing steps of generation rights trade are also discussed.Lastly,IEEE39-bus system is used to verify the proposed method.
