Energy storage plays the role of stabilizer and regulator in the comprehensive energy utilization of wind, light, biomass, gas and storage. A large number of distributed generators are connected to the distribution network, resulting in unstable supply and increasing peak valley difference of users' power consumption. Implement distributed microgrid energy storage in the distribution network and regulate the coordinated operation of distributed generators and loads; Make up for the negative impact of the randomness of distributed output on the safe and economic operation of power grid, and can participate in auxiliary services such as peak load regulation, frequency regulation and voltage regulation of power grid.
● Eulti energy input, basically realizing self use and reducing dependence on large power grid
● Efficient and flexible, suitable for a variety of renewable energy power generation systems
● AC bus connection for centralized management
● The energy storage system can realize the black start of microgrid
In remote areas, the traditional power grid is difficult to cover, but the local light resources or wind resources are rich, which is very suitable for establishing an independent micro grid for light (wind) storage and firewood to solve the problem of local power consumption.
● High power (above MW level) independent microgrid and AC bus scheme reduce the coupling of input sources and improve reliability
●The system operates under off grid regulation, and the energy storage system or diesel generator provides voltage and frequency support for the whole microgrid
●The energy management system (EMS) analyzes and forecasts the power consumption of photovoltaic, wind power and load, so as to realize the safe, reliable and economic operation of microgrid system
