摘要
以无功补偿方案全寿命周期净收益现值为目标函数,建立了多阶段配电网无功规划数学模型.不仅考虑了多阶段配电网无功规划方案的初始投资、运行维护成本、报废成本,反映了无功补偿方案全寿命周期的降损节能收益能力,还考虑了配电网在不同阶段的无功负荷需求,使无功补偿设备可以分阶段进行安装建设,优化了工程投资.提出了一种混沌多粒子群算法并对上述模型进行求解,该算法克服了基本粒子群算法早熟问题.最后,通过配电网无功规划实例验证了上述模型和方法的正确性及有效性.
The life cycle cost model of the multi-stage distribution network reactive power planning was presented. The initial investment, operation cost, maintenance cost, disposal cost of planning scheme were considered in the new planning model that based on the life cycle net present value of the planning scheme. The model not only showed the benefit of power loss reduction vividly, but also considered the distribution network reactive power demand in every stage, so the project investment was optimized. The improved algorithm based on the chaos multi-swarms particle swarm optimization algorithm was presen- ted. The new algorithm＇s global searching capability was improved. Finally, the new model was feasible and practical by a realistic reactive power planning project.
