【摘要】：主动配电网集成了丰富的可控资源,而当前配电网的无功电源规划并没有考虑主动管理手段,导致无功电源优化配置难以反映全面的综合性效益。针对此状况,考虑分布式电源、变压器分接头、储能、负荷调整等主动管理手段,计及主动配电网的时序特性,建立两层规划模型,在规划中考虑运行特性对电容器进行了综合优化配置,规划层考虑电容器的投资维护费用,运行层计及配电网的年运行费用,并采用基于小生境的遗传算法对两层规划模型进行优化求解。算例结果表明:在电容器规划中考虑主动管理手段,有利于提高资源利用率、降低配电网的投资和运行费用;充分利用分布式电源和储能的无功调节能力有利于配电网的安全经济运行。
[Abstract]:Active distribution network integrates a wealth of controllable resources, but the reactive power planning of the current distribution network does not consider active management means, resulting in the optimal allocation of reactive power supply is difficult to reflect comprehensive benefits. Considering the active management methods such as distributed generation, transformer tap, energy storage, load adjustment, and considering the timing characteristics of active distribution network, a two-layer planning model is established. In the planning, considering the operation characteristics, the capacitors are comprehensively optimized, the planning layer considers the investment and maintenance costs of the capacitors, and the annual operating costs of the distribution network are taken into account in the operation layer. And the genetic algorithm based on niche is used to optimize the two-level programming model. The results show that considering active management in capacitor planning is beneficial to improve the resource utilization ratio. Reduce the investment and operation cost of distribution network; Making full use of the reactive power regulation ability of distributed generation and energy storage is beneficial to the safe and economical operation of distribution network.
