针对高比例分布式电源接入下薄弱配电网馈线末端电压越限问题,从变电站端角度提出了计及自动电压控制(AVC)限值调整的配电网调压策略。首先,对配电网中主要可调设备和九区图控制策略进行线性化建模处理;然后,采用增强Epsilon约束法求解计及AVC限值调整的配电网多目标优化问题的Pareto前沿;最后,利用IEEE 33节点标准算例和中国浙江省某实际多馈线配电系统对所提方法进行验证。结果表明,所提方法可以降低可调设备日动作次数,提高设备使用寿命,并有效改善高比例光伏接入下的配电网电压波动问题。
In order to solve the problem of voltage overlimit at the feeder end of weak distribution network with high proportion of distributed generators
the voltage regulation strategy for distribution network considering automatic voltage control (AVC) limit adjustment is proposed from the substation perspective. First
linearization modeling is carried out for the main adjustable equipment and the nine-zone diagram control strategy in the distribution network. Then
the Pareto front of multi-objective optimization problem with AVC limit adjustment for the distribution network is solved by the enhanced Epsilon-constraint method. Finally
the proposed method is validated by an IEEE 33-bus standard case and a practical multi-feeder distribution system in Zhejiang Province
China. The results show that the proposed method can reduce the daily operation times of the adjustable equipment
increase the service life of the equipment
and effectively improve the voltage fluctuation of the distribution network with high proportion of photovoltaics.
