| 摘要: |
| 随着电力负荷的高速增长，近年来我国低电压问题日益突出，研究一种能够保证其综合效益的低电压综合治理策略具有重要的理论和实际意义。针对该问题，提出了一种基于安全效能成本(Safety Efficiency Cost, SEC)和改进信息间隙决策理论(Information Gap Decision Theory, IGDT)的配电网低电压综合治理方法。首先，以线路改造、无功补偿、变压器调压以及新建变电站为治理措施，构建了安全效能成本指标的数学表达式。然后，考虑负荷预测误差的不确定性，提出一种改进的信息间隙决策理论。以全寿命周期成本最小为目标，在满足安全指标和电压偏差指标的预期目标以及投资预算限制的情况下，构建基于改进IGDT的低电压综合治理双层鲁棒模型。最后提出了一种针对该规划模型的求解算法。仿真结果验证了所提方法的正确性和有效性。 |

| Abstract: |
| With the rapid growth of power load, the problem of low voltage in China has become increasingly prominent in recent years. It is of great theoretical and practical significance to study a low voltage comprehensive control strategy that can ensure its benefits. This paper proposes a low voltage comprehensive control method based on Safety Efficiency Cost (SEC) and improved Information Gap Decision Theory (IGDT). First, taking line transformation, reactive power compensation, transformer voltage regulation and a new substation as the treatment measures, a mathematical expression for a safety efficiency cost index is constructed. Then, considering the uncertainty of load forecasting error, an improved Information Gap Decision Theory (IGDT) is proposed. With the goal of minimizing the life cycle cost and satisfying the expected goal of safety index, voltage deviation index and investment budget limit, a two-layer robust model of low voltage comprehensive management based on improved IGDT is constructed. Finally, an algorithm for solving the programming model is proposed. The simulation results verify the correctness and effectiveness of the proposed method.
