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.More
As discussion around development of a smart grid has steadily increased, so too has talk about smart microgrids. A critical ingredient for smart microgrids is energy storage. Energy storage can play a major role in facilitating use of renewable energy resources to power microgrids, while also protecting power stability and reliability within the microgrid. This technology has advanced significantly in recent years, and the latest technology holds many promising benefits for microgrid applications. In fact, these new technologies require a complete rethinking of what microgrids are capable of doing.
Some of the topics discussed in this paper include:
This paper will also look at a few real-world applications of energy storage within a microgrid.
