摘  要：
针对越来越多的分布式电源接入农村配电网,导致电压无功控制难度增大的问题,提出了适用于含分布式电源农村配电网的电压无功优化控制方法,通过调控分布式电源无功出力、调整有载调压变压器分接头位置、投切无功补偿设备等手段,建立了考虑分布式电源利用率、网损、电压波动和无功设备投切费用的多目标协调优化控制模型,并采用收敛性较好的协同粒子群算法进行求解.最后,算例仿真验证了所提模型和算法的正确性与有效性.

摘  要：
Due to the randomness,volatility and intermittent characteristics of distributed generation,more and more distributed generation are connected to rural distribution networks,which makes the voltage reactive power control in rural distribution network more difficult. For the problem of voltage reactive power optimization in active distribution network,considering the reactive power compensation effect of distributed generation to distribution network,a voltage reactive power optimization control method suitable for rural distribution network which had distributed generation was proposed. By regulating the reactive power output of the distributed generation,adjusting the tap position of the on-load tap changer,and switching the reactive power compensation equipment,the safe and reliable economic operation capability of the rural active distribution network can be effectively improved. The multiobjective coordinated optimization control model considering the distributed generation utilization rate,network loss,voltage fluctuation and reactive power equipment switching cost was established. A wellconverged cooperative particle swarm optimization algorithm was used to solve the multi-objective optimization problem. Finally,the IEEE 13 node power distribution system was used for simulation calculation,and compared with several multi-objective optimization algorithms,and the feasibility and effectiveness of the proposed model and algorithm were verified.
