摘　　要：为了提高配网系统的供电可靠性,解决目前电能供给不足和产能成本较高等问题,针对含混合电源的配网系统进行了年度电力电量平衡分析。首先,采用场景树生成法对年内的风光负荷数据进行抽样选择,依据概率原理在每月中选取3个典型日以反映全年的风光发电和负荷特征。其次,考虑到风光电站、燃气轮机机组、蓄电池和连续、离散无功补偿装置的运行约束,建立了以年运行成本最低为目标的配电网系统优化模型,其优化求解问题为二阶锥规划模型,采用Yalmip优化求解工具对配网系统进行建模,并用Gurobi商业求解器对各典型日的电力电量平衡问题进行求解。基于成都市的太阳辐射、温度、风速、电力负荷等数据,以IEEE33节点配网系统设计算例,最终实现年电力电量平衡的产能分布和经济性分析。In order to improve the power supply reliability of the distribution network system,solve the current problems of insufficient power supply and high production cost,an annual power balance analysis was conducted for the distribution network system with hybrid power sources.First,the scene tree generation method was used to sample and select the wind power,photovoltaic,and load data within the year.Three typical days were selected in each month according to the probability principle to reflect the characteristics of wind and wind power generation and load throughout the year.Secondly,considering the operating constraints of wind and solar power plants,gas turbine units,batteries,and continuous and discrete reactive power compensation devices,an optimization model of the distribution network system was established to minimize with the goal of minimizing the annual operating cost.The optimization solution problem is a second-order cone programming model.The Yalmip optimization solution tool was used to model the distribution network system,and the Gurobi solver was used to solve the power balance problem of each typical day.Based on the solar radiation,temperature,wind speed,power load of Chengdu,the design example of the IEEE 33-node distribution network system is used to finally realize the production capacity distribution and economic analysis of the annual power balance.
