模糊集对分析法应用于计及ATC的多目标电网规划

Application of Fuzzy Set Pair Analysis in Multi-objective Transmission Network Planning Considering ATC

针对多目标电网规划,提出了基于模糊集对分析法的模型。综合考虑方案的经济性、可靠性和灵活性,使优化方案的综合效益达到最佳。经济性指投资费用,可靠性采用需求方的缺电成本衡量,灵活性首次引用可用输电能力(ATC)来量化。引入灵活性可提高优化方案对未来不确定环境的适应能力,避免不必要的补偿投资。模糊集对分析法对规划方案进行2次对立刻画,评价更加全面。算例证明了该方法的有效性。

To solve the problems on multi-objective transmission network planning, a novel model based on fuzzy set pair analysis （FSPA） is presented, in which the economy, reliability and flexibility of the schemes are all taken into account to achieve the optimum overall benefit. The investment cost is introduced to indicate economy, the outage cost of customers is adopted to evaluate the reliability, and available transfer capability （ATC） is proposed to quantify the flexibility of the network for the first time. The introduction of flexibility into the objective function can improve the adaptability of the optimal scheme to the future uncertain environment and effectively avoid unnecessary compensation investment. The planning schemes are oppositely depicted twice by FSPA, and the estimated results are more comprehensive. The sample results have proved its validity.
