With energy storage as the core, build an integrated self-supply power system of wind power, photovoltaics, energy storage, and diesel generation: when grid-connected, it can reduce electricity costs through peak-valley arbitrage and new energy accommodation; when off-grid, energy storage acts as a stabilizer and backup power to smooth out wind and solar output fluctuations, ensuring stable power supply for critical loads in scenarios like parks, islands, and mining areas. The system is equipped with a microgrid energy management platform to realize intelligent scheduling of multiple energy sources, providing users with a highly reliable, low-energy-consumption, and green low-carbon local power solution.
