Problems solved by technology

Existing research on its power generation operation mode is relatively lacking, and hydropower stations and pumped storage power stations cannot be used at the same time to solve the fluctuation of photovoltaic and wind power output
In addition, the existing technology cannot reasonably simulate the power generation operation process of such bases, which limits the scale demonstration and construction implementation of the project

Abstract

The invention relates to a power generation scheduling method and device for a clean energy base, and the method comprises the steps: calculating a difference value between the natural total output of photovoltaic power generation, wind power generation and hydroelectric generation of the clean energy base at the current time period and a target load, and taking the difference value as a net load; determining an energy storage working mode of the clean energy base according to positive and negative of the net load; when the net load is negative, enabling the clean energy base to operate an energy storage working condition, and calculating first working power of hydroelectric energy storage and first energy storage power of pumped storage; controlling the total system output of the clean energy base according to the first working power and the first energy storage power, so that the total system output is equal to the target load; when the net load is positive, enabling the clean energy base to operate a power supply working condition, and calculating second working power of hydroelectric energy storage and second energy storage power of pumped storage; and controlling the total system output of the clean energy base according to the second working power and the second energy storage power, so that the total system output is equal to the target load.

Description

technical field [0001] The present disclosure relates to the technical field of clean energy, and in particular to a method and device for dispatching power generation of a clean energy base. Background technique [0002] Photovoltaic power generation is a technology that converts light energy into electrical energy by using the photoelectric effect of semiconductors. Wind power generation is a technology that converts wind kinetic energy into electrical energy. Their power generation process is determined by solar radiation and wind power respectively. The output process is affected by weather, day and night, Seasonal and other factors, fluctuate greatly. When photovoltaic power plants or wind farms are connected to the grid for power generation, their unstable output process has a greater impact on the grid, which is not conducive to grid stability. The hydropower station uses the potential energy of water to drive the water turbine to generate electricity, and the water ...
