Abstract

The invention relates to a photovoltaic power generation and power grid complementary direct current smelting furnace power supply system and method, which belong to the field of electromagnetic metallurgical equipment. The system comprises a photovoltaic power generation system, an electric furnace power supply system and an electric furnace smelting system, wherein the photovoltaic power generation system comprises a photovoltaic electric field and an energy storage system. On the basis of distributed optimal control photovoltaic power generation system and power grid complementation, power is supplied to an electric furnace smelting system, and by detecting the power generation state of the photovoltaic power generation system and the smelting power demand of a direct-current smelting furnace in real time, whether the output of the photovoltaic power generation system is matched with the power demand of the smelting furnace or not is judged; therefore, the switching state of the photovoltaic power generation system and the electric furnace power supply system is adjusted, and the power demand of normal operation of the electric furnace smelting system is ensured. The power supply quality of the photovoltaic power generation system is improved, meanwhile, large-scale local consumption of photovoltaic power generation energy can be realized, the problems of high market consumption and power transmission cost and the like faced by photovoltaic power generation are effectively solved, and the power utilization cost of a production enterprise is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of boilers, and relates to a DC smelting furnace power supply system and method in which photovoltaic power generation and power grids are complementary. Background technique [0002] Photovoltaic power generation is an important way to utilize solar energy. It has the advantages of no risk of exhaustion, safety and reliability, no noise, no pollution emissions, high energy quality, absolutely clean (no pollution), short construction period, and short time spent in obtaining energy. It plays an important role in the country's long-term energy strategy. However, for a long time, due to insufficient market consumption of photovoltaic power generation, complex peak-shaving and frequency-regulation technology, and high power transmission costs, some places have experienced relatively serious light-saving and power-limiting phenomena. The energy output by photovoltaic power generation has not been fully utilized,...
