| 摘 要： | 电力弹簧作为一种新型负荷侧调节设备,与具有宽电压范围的非关键负载串联形成智能负载,自动调节用电量与发电量匹配,以实现配电网运行优化。研究了含有电力弹簧的主动配电网最优潮流模型,提出了一种基于果蝇优化算法的智能负载优化方法,松弛法被用于推导最优潮流的二阶锥规划公式。结果表明,智能负载的主动调节可以优化配电网电压水平,降低有功网损,降低配电网的运行成本。所提多目标优化模型在一个改进的IEEE-33节点模型中求解,仿真结果验证了其正确性和有效性。

| Abstract: | As a new type of demand-side adjusting device, the electric spring (ES) forms a smart load in series with non-critical loads with a wide voltage range to automatically adjust the power consumption to match the power generation so as to optimize the operation of ADN. In this paper, the optimal power flow (OPF) model of ADN with ES is researched, and a smart load optimization method based on fruit fly optimization algorithm is proposed, and approximation technique is used to derive the second-order cone programming formula of OPF. The active adjustment of the smart load can reduce the voltage deviation, the transmission loss, and the operational cost of ADN. The proposed multi-objective optimization model is used in a modified IEEE 33-bus distribution system. Simulation results validate the proposed optimization model and algorithm. |
