A source network load storage collaborative power system output modeling analysis method

Abstract

The application relates to the technical field of dynamic modeling, and proposes a power generation modeling analysis method for a source-grid-load-storage collaborative power system, which comprises the following steps: collecting photovoltaic data and illumination weather data of a photovoltaic panel, fitting a curve equation of irradiance and light rejection rate according to a photovoltaic data curve; obtaining a sunshine duration of a natural day to which a collection time point belongs, a peak value of a steady-state reference component of solar irradiance, and the steady-state reference component of solar irradiance at the collection time point, and constructing a solar irradiance model; calculating a solar altitude angle and a solar azimuth angle at the collection time point, and a photovoltaic output value at the collection time point, and constructing a photovoltaic output model; simulating a future weather state, combining the solar irradiance model and the photovoltaic output model, and realizing photovoltaic output simulation. The application can improve the accuracy of the photovoltaic output model.
