加强电网网架建设、采用有载调压变压器和光伏逆变器调节对改善分布式光伏接入中、低压配电网所产生的影响效果显著。“十三五”期间,我国分布式光伏发电将快速发展,局部地区渗透率较高,将给电力系统带来多方面影响,需要从整个电力系统角度采取经济有效的技术措施。目前可采取的措施包括电网改造、配置储能、逆变器有功和无功控制等多种源-网-荷侧的策略,各种措施实施效果和成本投入相差较大,且在城市和农村电网、中压和低压电网也具有较大差别,需要开展综合评估。国网能源研究院新能源与统计研究所的黄碧斌博
Strengthening grid grid construction, the use of on-load tap-changers and PV inverters to improve the distribution of distributed PV access, the impact of low-voltage distribution network has a significant effect. During the “13th Five-Year Plan” period, the distributed photovoltaic power generation in our country will develop rapidly and the penetration rate in some areas will have a great impact on the power system. Therefore, it is necessary to adopt cost-effective technical measures from the perspective of the entire power system. At present, the measures that can be taken include various source-grid-load-side strategies such as power grid reconstruction, energy storage configuration, active and reactive power control of inverters, etc. The implementation effects and cost inputs of various measures differ greatly, and in cities and rural areas Power grid, medium voltage and low voltage power grid also have great differences, need to carry out a comprehensive assessment.
