In order to actively respond to the goal of " carbon peak · carbon neutralization, " Yongmei Group builds a multi-energy complementary system dominated by renewable energy to promote the coordinated development of coal and new energy. Combined with the actual situation of five pairs of mines, through the system integration of photovoltaic, wind power, heat pump, energy storage and other key technologies, make full use of the idle land, roof and coal mining subsidence area and other space resources in the mining area, layout of distributed photovoltaic and wind power generation facilities, and combined with the existing gas power generation capacity, build a ' wind-light-gas ' multi-coordinated clean power supply system, and put forward a set of multi-complementary and cascade energy utilization system covering source-network-load-storage coordination. Through the integrated construction of wind, solar and energy storage, waste heat resource recovery and efficient utilization of gas, the scheme has achieved remarkable energy saving and emission reduction and economic benefits.
