Description

technical field [0001] The invention is a photovoltaic high-permeability grid voltage optimization method based on an energy storage battery. Background technique [0002] As a form of renewable energy power generation, distributed photovoltaic power generation has the advantages of high efficiency, high quality, clean and environmental protection. According to statistics, as of the end of 2015, my country's cumulative installed capacity of photovoltaic power generation was 43.18 million kW, becoming the country with the largest installed capacity of photovoltaic power generation in the world. Among them, distributed photovoltaic installed capacity was 6.06 million kW, accounting for 14%. The distributed photovoltaic industry has been included in my country's "Thirteenth Five-Year Plan" as a key development target, with rapid development and broad prospects. [0003] After distributed photovoltaics are connected to the distribution network, the traditional distribution net...
