主动配电网无功补偿设备配置及电压优化策略OA

Current practices for allocating reactive power compensation devices often neglect the comprehensive eco-nomic performance arising from the coordinated operation of these devices with other dispatchable resources in ac-tive distribution networks(ADNs).To address this,this paper proposes an optimal strategy for reactive power com-pensation device allocation and voltage optimization in active distribution networks.A bi-level model integrating allo-cation and operation is established.The upper-level allocation model aims to minimize the investment and mainte-nance costs of reactive power compensation devices as well as the total system operating cost.The locations and ca-pacities of the compensation devices are then generated and passed to the lower-level model.The lower-level opera-tion model targets minimizing the total operating cost and voltage deviation under the coordinated operation of reac-tive 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 pro-posed 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.
