【摘要】：主動(dòng)配電網(wǎng)集成了豐富的可控資源,而當(dāng)前配電網(wǎng)的無(wú)功電源規(guī)劃并沒(méi)有考慮主動(dòng)管理手段,導(dǎo)致無(wú)功電源優(yōu)化配置難以反映全面的綜合性效益。針對(duì)此狀況,考慮分布式電源、變壓器分接頭、儲(chǔ)能、負(fù)荷調(diào)整等主動(dòng)管理手段,計(jì)及主動(dòng)配電網(wǎng)的時(shí)序特性,建立兩層規(guī)劃模型,在規(guī)劃中考慮運(yùn)行特性對(duì)電容器進(jìn)行了綜合優(yōu)化配置,規(guī)劃層考慮電容器的投資維護(hù)費(fèi)用,運(yùn)行層計(jì)及配電網(wǎng)的年運(yùn)行費(fèi)用,并采用基于小生境的遺傳算法對(duì)兩層規(guī)劃模型進(jìn)行優(yōu)化求解。算例結(jié)果表明:在電容器規(guī)劃中考慮主動(dòng)管理手段,有利于提高資源利用率、降低配電網(wǎng)的投資和運(yùn)行費(fèi)用;充分利用分布式電源和儲(chǔ)能的無(wú)功調(diào)節(jié)能力有利于配電網(wǎng)的安全經(jīng)濟(jì)運(yùn)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.
