Energy Storage in Smart Microgrids

All power systems also require the capability to balance, in real time, differences between load demand and generator output. This balancing capability—which keeps system frequency at the level where it’s designed to operate—is critical to ensure the stability and reliability of the overall power system, for both centralized power grids as well as microgrids. In a centralized grid, fossil-fuel-fired generating plants typically will ramp up or down to ensure demand and generation output remains in balance.
