摘　　要：在电力市场环境下,考虑购电成本对电网交易能力的影响,建立兼顾电网交易能力和购电成本的多目标交易优化模型,运用模糊建模的方法将多目标优化问题转化为求解最大满意度的单目标非线性规划问题,采用原对偶内点法求解。通过对IEEE-30节点测试系统进行仿真计算,结果表明所提出的多目标交易优化模型,可以在提高交易能力的同时尽量减小购电成本,验证了模型及算法的有效性。Considering effects of the cost of purchasing electricity on the power trading ability in electricity market, a multi-objective optimal scheduling model is established in which both power trading ability and electricity purchasing cost are considered, and the multi-objective optimization is reform- ulated into a nonlinear single-objective programming problem by means of fuzzy satisfaction-maximizing method, and solved by the primal-dual interior point method. The simulation by IEEE-30 bus test system shows that using the proposed multi- objective model the power trading ability can be increased while the electricity purchasing cost can remain as little as possible, verifying the validity of the model and algorithm.
