摘要
为了解决配电网电压质量较差的问题,提出了一种基于多级协调的配电网电压质量优化方法,利用改进型原始对偶内点法对各级变压器、无功补偿装置、调压设备进行综合协调和全局控制,从而降低电网电压偏移度,改善电压质量。并以某地区配电网实际参数为算例,对多级协调的配电网电压质量优化方法进行验证,结果表明,该方法能够有效降低系统电压偏移度、网络损耗,对于提高配电网的电压质量有很好的应用价值。
In order to solve this problem of poor voltage quality of distribution network,this paper proposes a voltage quality optimization method based on multi-level coordination.Transformers,reactive power compensation device,voltage regulating device are coordinated globally to reduce voltage offset and improve voltage quality.The actual parameters of a regional distribution network is taken as an example to verify the voltage quality optimization method of distribution networks based on multi-level coordination,and the result shows that the method can reduce the system voltage offset and network loss,and it has great value for voltage quality improvement of the distribution network.
