Description

technical field [0001] The invention relates to a real-time simulation modeling method for a high-permeability distributed photovoltaic power generation cluster, and belongs to the technical field of distributed energy grid-connected modeling and simulation. Background technique [0002] As a typical distributed power source, photovoltaic power generation has become an important way for human beings to use renewable energy to generate electricity. Therefore, it is of great significance to study the simulation modeling of photovoltaic system power generation process. However, the stability of power system frequency has high requirements for renewable energy power generation. Solar power generation has the characteristics of intermittent, fluctuating and unschedulable. Therefore, large-scale distributed photovoltaic power generation The problem of weak capacity. At the same time, the gradual increase in the penetration rate of the power grid has led to the introduction of a ...
