摘要(Abstract)：

当前无功补偿设备配置时未考虑无功补偿设备与主动配电网可调资源协同运行带来的综合经济性，因此，提出主动配电网无功补偿设备配置及电压优化运行策略。构建了配置-运行双层模型，上层配置模型以无功补偿设备投资维护成本和系统运行总成本为优化目标，生成无功补偿设备的安装位置和容量，并将结果传递给下层；下层运行模型根据上层传递的信息，考虑无功补偿设备与主动配电网可调资源协同运行下的总成本和电压偏差两个目标，进行多目标优化求解，并将运行结果返回给上层来引导迭代优化的方向。在改进的IEEE 33节点系统进行算例验证，结果表明所提出的无功补偿设备配置方案，能够保证主动配电网配置和运行的综合经济性以及电压质量。
Current practices for allocating reactive power compensation devices often neglect the comprehensive economic performance arising from the coordinated operation of these devices with other dispatchable resources in active distribution networks(ADNs). To address this, this paper proposes an optimal strategy for reactive power compensation device allocation and voltage optimization in active distribution networks. A bi-level model integrating allocation and operation is established. The upper-level allocation model aims to minimize the investment and maintenance costs of reactive power compensation devices as well as the total system operating cost. The locations and capacities of the compensation devices are then generated and passed to the lower-level model. The lower-level operation model targets minimizing the total operating cost and voltage deviation under the coordinated operation of reactive power compensation devices and dispatchable resources in ADNs. The multi-objective optimization problem is solved based on the information provided by the upper level. The results were then fed back to the upper level to guide iterative optimization process. Case studies on the modified IEEE 33-node system demonstrates that the proposed allocation scheme for reactive power compensation devices ensures both the overall economic performance in allocation and operation and voltage quality of the active distribution networks.
