  • How to adjust the wind power supply of base station

    How to adjust the wind power supply of base station

    Very simply, supply must be continuously matched to demand. There is no large-scale storage of electricity on the grid. Load is the amount of power in the electrical grid. Base load is the level that it typically does not go below, that is, the basic amount of electricity that is always. Base load is typically provided by large coal-fired and nuclear power stations. They may take days to fire up, and their output does not vary. Peak load, the variable. Wind power has no effect on base load. However, since base load providers can not be ramped down, if wind turbines produce power when there is no or little. Unlike conventional power plants, wind turbines cannot be “dispatched” in response to fluctuating demand needs. Wind turbines respond only to the wind, so.
