| 摘要: |
| 电网电压支撑是源（发电与负荷）网协调合作的结果。电力系统中输配交融，电能双向流动，源网间呈现交织纠结的矛盾，导致仅依赖于源的调整的电压支撑方式出现非同调现象。在源平衡方式给定的前提下，将电网结构状态调整纳入决策量，建立考虑变压器过负荷闭锁调档限制的电压支撑决策模型，并由遗传算法和非线性原对偶内点法组合求解。算例分析证明了所提方法的有效性，显现应对未来电力系统多变情形下实施源网协同的必要性。 |

| Abstract: |
| The voltage support of power system is the result of coordination and cooperation between source（generation units and loads） and grid. The integration of transmission and distribution systems and the bidirectional power flow in power system result in the complex contradiction between source and grid，which causes the incoherent phenomenon in the source-dependent voltage support of power network. A voltage-support decision-making model with the constraint of transformer over-load tap-changing blocking is built and solved by the combination of the genetic algorithm and the nonlinear primal-dual interior point method，which takes the conditional adjustment of power grid structure as a decision-making variable when the source balance mode is given. Case analysis verifies the effectiveness of the proposed method，showing the necessity of implementing the synergy between source and network in future multivariate power system. |
