| 摘要: |
| 源（发电与负荷）网间关系的处理是电力系统运行与控制的核心问题，新形势下源网间呈现日趋交织纠结的矛盾。提出一种源网间协同的经济调度模型，该模型在经济调度原有条件的基础上，将电网设备状态纳入决策量，以互补形式表达电网设备的运行约束。将非凸多项式优化问题映射到矩量空间，以矩量半定规划凸松弛方法转换为标准的半定规划模型，并采用半定规划优化器SDPA求解模型。算例分析验证了所提方法的有效性。 |

| Abstract: |
| The treatment of the relation between power source and network is the core of power system operation and dispatch. As the contradiction between power source and network becomes increasingly sophisticated，an economic dispatch model with the synergy between electric power source and network is proposed based on the original conditions of economic dispatch，which takes the status of network equipment as a decision-making variable and expresses the operational constraints of network equipment in a complementary form. The nonconvex polynomial optimization problem is projected into the moment space，which is then converted into a standard semi-definite programming model by the moment-based semi-definite programming convex relaxation method and solved by the semi-definite programming optimization solver SDPA. Case analysis verifies the effectiveness of the proposed method. |
| Key words: electric power systems economic dispatch synergy between source and network moment-based semi-definite programming complementarity models |
