| 在配电网安装可接受调度中心控制指令的智能用电开关设备是电力系统调度部门调用需求侧资源迅速做出反应的重要举措。为了在满足负荷调控需求的同时降低成本，提出一种计及多维紧急负荷调控目标的智能用电开关设备优化配置方法。首先，基于紧急负荷控制体系下上层智能用电开关动作与下层智能用电开关动作的切负荷耦合作用，解析构建了智能用电开关安装决策变量与切负荷执行变量组合关系的关联约束。其次，构建兼顾开关安装与运营成本、紧急负荷调控均衡性以及切负荷经济效益的混合整数非线性规划模型。最后，基于示意性9节点主配电网混合系统以及我国某区域341节点系统结合实际负荷数据进行了仿真分析，结果表明所提方法可充分发挥不同设备的作用与组合作用优势，在满足电网负荷调控需求的同时提升智能用电开关设备配置的经济性。 |

| Abstract: |
| The installation of intelligent power switch devices in distribution networks, capable of receiving dispatch control commands from power system operators, represents a critical initiative for enabling rapid demand-side resource response. To meet emergency load regulation requirements while reducing costs, this paper proposes an optimal configuration method for intelligent power switch devices considering multi-dimensional emergency load regulation objectives. First, based on the coupling mechanism between upper-layer and lower-layer intelligent switch operations in emergency load control systems, the correlation constraints between device installation decision variables and combinations of load shedding execution variables are analytically established. Subsequently, a mixed-integer nonlinear programming model is developed to holistically optimize switch installation/operation costs, emergency load regulation equilibrium, and economic benefits of load shedding. Finally, simulation analyses are conducted using a 9-node primary distribution hybrid system and a real 341-node regional power system in China with actual load data. The results demonstrate that the proposed method effectively leverages the functional characteristics and synergistic advantages of diverse device combinations, achieving enhanced economic efficiency in intelligent switch configuration while satisfying the grid’s load regulation demands. |
