Title:
PHOTOVOLTAIC POWER GENERATION AND ENERGY STORAGE CONTROL METHOD AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/021549
Kind Code:
A1
Abstract:
The present invention relates to the technical field of photovoltaic power generation and energy storage. Disclosed is a photovoltaic power generation and energy storage control method, comprising: S1, acquiring photovoltaic generated power and load power, comparing the photovoltaic generated power with the load power, and if the photovoltaic generated power is not less than the load power, executing S2, otherwise, executing S3; S2, controlling a photovoltaic generation system to supply power to a load and an energy storage device; S3, acquiring a real-time electricity price, comparing the real-time electricity price with a preset electricity price, and if the real-time electricity price is greater than the preset electricity price, executing S5, otherwise, executing S4; S4, controlling a power grid to supply power to the load, and controlling the photovoltaic generation system and the power grid to supply power to the energy storage device; S5, controlling the photovoltaic generation system and the energy storage device to supply power to the load; and S6, after the capacity of the energy storage device reaches warning capacity, switching to the power grid to supply power to the load. The photovoltaic power generation and energy storage control is performed by means of the change in the real-time electricity price, and the use of electric energy is finely managed, so that the electricity costs of the load can be effectively reduced.
