摘　　要：为提升光伏发电机组接入中低压配网后的电能输送质量、降低网损率,基于混合整数凸规划,完成配电网的无功补偿配置研究。该方法以含光伏发电的中低压配网最小网损为目标,构建配电网无功补偿数学模型。实验结果表明:该方法应用后中低压配网节点电压标幺数值得到有效提升,且随着配电网运行时间的增加,其降低幅度较小;可有效降低中低压配网的网损率,应用效果显著。To enhance the power transmission quality of photovoltaic generator units integrated with medium and low voltage distribution networks and to minimize network loss rates,this paper explores the configuration of reactive power compensation within the distribution network based on mixed integer convex programming.Taking the minimum network loss of the medium and low voltage distribution network with photovoltaic power generation as the goal,the proposed method constructs a mathematical model of reactive power compensation of the distribution network.The findings from the experimental evaluations indicate that the application of the proposed method significantly reduces the per-unit voltage at the nodes of the distribution network.Moreover,it is observed that as the network's operational time increases,the reduction in voltage amplitude becomes marginally less pronounced.The model has been proven to effectively mitigate the loss rate in medium and low voltage distribution networks,offering a notable improvement in practical application outcomes.
