Electrical Energy Storage (EES) refers to the process of converting electrical energy into a stored form that can later be converted back into electrical energy when needed.1 Batteries are one of the most common forms of electrical energy storage, ubiquitous in most peoples'' lives. The first battery—called Volta''s cell—was developed in 1800. The first U.S. large
Connecting Energy Storage Guidance. Energy storage technology allows the capture of generated energy when it is supplemental to needs, so that it can be stored and released at times when it is needed, for example, at times of peak demand. It provides the ability to instantaneously balance power supply and demand and can support power quality
Fig. 1. Energy storage tied to the power grid can serve a variety of functions, from smoothing of momentary changes in load or renewable generation, to day-long shaving of the peak demand (Reproduced from Hearne 2014) Full size image. Another key role of energy storage is in support of energy efficiency initiatives.
Defining V2G grid codes is important to allow EVs to connect easily to, and smartly exchange energy with, the grid. The codes allow smart and bidirectional charging, which helps control peak loads and provides many other grid benefits. Those benefits can reduce investments in the grid and in distribution transformers and cables by approximately
