基于OPENDSS仿真平台的分布式光伏接入对配电网的影响分析

摘要

In order to support and serve the large capacity and high density distributed photovoltaic to integrate smoothly into the distribution network of Jiaxing photovoltaic high-tech industrial park,ensure the safe absorption of solar photovoltaic power,and guarantee the safe,stable and economic operation of Jiaxing power grid,the influence of distributed photovoltaic integration on the distribution network is analyzed and the absorption capacity of photovoltaic industrial park is evaluate.Based on the simulation power network of photovoltaic industrial park on OPENDSS platform,the grid voltage,active powerflow and loss index after the integration of photovoltaic generation into the distribution network are analyzed,the technical problems of distributed photovoltaic in the integration process are explored,providing scientific reference for making distributed photovoltaic generation integration plan of photovoltaic industrial park.%为支持、服务嘉兴光伏高新技术产业园区大容量高密度分布式光伏的顺利并网,确保安全消纳太阳能光伏发电,保障嘉兴电网安全稳定和经济运行,开展了分布式光伏接入对配电网的影响分析,用以评估光伏产业园区光伏发电接纳能力.文章通过OPENDSS(OPEN distributed system simulator)平台对光伏产业园区电网进行了仿真,分析了光伏并网后的电网电压、有功潮流和线损等指标,探讨分布式光伏发电并网过程中的技术问题,可为合理制定产业园区的分布式光伏接入规划方案提供科学的参考依据.
