引入了向量序优化理论求解输电网的多目标静态规划问题。以最大化输电方、发电方以及用户方电力市场三大成员的自身利益为优化目标,建立了以输电网扩建投资最小、系统发电费用最小、以及负荷损失费用最小为优化目标的多目标规划模型,并采用向量序优化理论求解足够好的全局非劣解。基于Garver系统的仿真试验表明,充分利用了各子目标的优化信息,克服了大规模输电网规划过程中存在的"维数灾"问题,并大幅度提高了计算效率,使优化求解时间由41.7 h下降为0.26 h,降低了99.4%。

The Planning Method of Multi-Objective Transmission Network Based on Vector Ordinal Optimization Theory

The vector ordinal optimization theory is firstly introduced to solve the multi-objective static transmission network planning problem. To maximize the benefits of transmission owners, generators and customers, a multi-objective optimization model considering minimization of expansion of investment costs, generation costs and possible outage costs respectively is built. Then vector ordinal optimzation theory is used to get the good enough solutions. The Garver system simulation results show that the method makes full use of the information from the multiple objectives, overcomes the curse of dimensionality and significantly improves the computational efficiency. The computation time is decreased from 41.7h to 0.26h, reducing about 99.4%.
