Abstract

The invention provides a photovoltaic output distribution method and device of of multiple power distribution station areas, and relates to the technical field of photovoltaic consumption. The methodcomprises the following steps: dividing power distribution station areas into a first type of power distribution station areas and a second type of power distribution station areas; respectively collecting power distribution data of the first type of power distribution station areas and the second type of power distribution station areas after every preset period; respectively screening out stations with excessive photovoltaic output in the two types of power distribution station areas; allocating the redundant photovoltaic output of the power distribution station areas with the excessive photovoltaic output in the first type of power distribution station areas to the power distribution station areas without excessive photovoltaic output for consumption, and allocating the redundant photovoltaic output of the second type of power distribution station areas to the power distribution station areas without excessive photovoltaic output for consumption; and allocating the redundant photovoltaic output of the first type of power distribution station areas to the power distribution station areas without excessive photovoltaic output in the second type of power distribution station areasfor consumption. By adoption of the photovoltaic output distribution method and device provided by the invention, the excessive photovoltaic output can be consumed, thereby greatly reducing the lightrejection rate, reducing the impact effect of the photovoltaic power generation on large power grids, and improving the reliability of the photovoltaic power supply.

Description

technical field [0001] The invention relates to the technical field of photovoltaic accommodation, in particular to a method and device for distributing photovoltaic output in a multi-distribution station area. Background technique [0002] The impact of large-scale photovoltaic power generation when it is integrated into the large power grid will bring adverse effects to the large power grid and bring difficulties to photovoltaic consumption. If the power generation output does not match the load characteristics, real-time power balance cannot be achieved, resulting in The phenomenon of light abandonment affects the reliability of power system power supply. The phenomenon of light abandonment not only causes waste of clean energy, but also causes a sharp decline in the economic benefits of power generation companies, affecting the healthy development of new energy in my country. [0003] With the increase of photovoltaic penetration rate, how to ensure the reliability of p...
