计及输电灵活性期望代价的多目标电网协调最优规划

为综合解决输电网规划中的多目标协调问题,提出了以投资费用、运行维护成本、输电扩展灵活性期望代价和社会福利损失4个指标达到最小的多目标优化模型.该模型引入了适应未来不确定场景的输电灵活规划期望代价,并从适应负荷增长不确定性和电网故障发生的不确定性2个方面建立了相应的灵活性期望代价模型.应用层次分析法分析每个目标函数评价因素之间的重要性约束度,进而构建判断矩阵,以确定每个目标函数在最优模型中的权重.最后,18节点系统的电网扩展规划算例验证了所述方法的有效性.

Multi-objective Optimal Coordinated Transmission Expansion Planning Considering Flexibility Expected Expense

To solve the multi-objective coordinated problem of transmission networks planning,an optimal planning model is presented,in which the multi-objective function consists of the minimum investment cost,minimum operation and maintenance cost,minimum flexibility expected expense and minimum social welfare expense.The flexibility expected expense of adapting to the uncertain future is taken into account in the optimal model and is presented from the uncertain scenarios of load growth and power networks emergency...
