| 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: |
| Though the active distribution network integrates rich controllable resources, the present reactive-power planning of distribution network does not take the active managements into consideration, resulting in that the reactive-power optimization hardly reflects the fully comprehensive benefits. A two-layer planning model is established based on the time-sequence characteristics of active distribution network, which considers the active managements, such as distributed generation, transformer tap, energy storage, load regulation, etc. Capacitors are optimally configured according to their operational characteristics in the planning. The investment and maintenance costs of capacitors are considered in its planning layer while the annual operational cost of distribution network is considered in its operating layer. The genetic algorithm based on ecological niche is applied to solve the model. Simulative results show that, the active managements considered in the capacitor planning help to improve the resource utilization rate and reduce the investment and operational costs of distribution network; the full use of the reactive-power regulation ability of distributed generations and energy storage is conducive to the safe and economic operation of distribution network. |
