摘要
在考虑风光荷时序特性的基础上,引入含需求侧响应的主动管理技术建立了一种新的分布式电源准入容量数学模型,并进行了仿真研究,即先采用K均值聚类多场景分析法得到四季风光荷典型日时序功率曲线;然后引入含需求侧响应的主动管理方式,考虑电网静态安全约束和主动管理约束,建立分布式电源准入容量计算模型,并采用改进粒子群算法对准入容量进行求解;根据系统净负荷曲线,引入净负荷率指标对接入分布式电源后的配电网进行综合评价,以验证模型的优越性。该模型对IEEE33节点配电网系统的仿真表明,考虑含需求侧响应的主动管理系统可接纳更多新能源,有效降低系统负荷峰谷差,为实际配电网工程提供了依据。
Based on the wind photovoltaic load time series characteristics,a novel distributed power supply capacity mathematical model was established and simulated by introducing active management technology with demand side response.Firstly,the K means clustering multi-scenario analysis method was used to obtain the typical daily time series power curve of the four seasons.Then the active management method with demand side response was introduced.Considering the static security constraints and active management constraints of the grid,a distributed power admission capacity calculation model was established.The improved particle swarm optimization algorithm was used to solve the problem.According to the system net load curve,the net load rate index was introduced to comprehensively evaluate the distribution network after accessing the distributed power source to verify the superiority of the model.The simulation was carried out through the IEEE33 node distribution network system.The results show that the system can accommodate more new energy and effectively reduce the peak to valley difference of the system load when considering active management with demand response.This model provides a basis for actual distribution network engineering.
