The key issues in the optimal configuration of distributed energy storage are the selection of location, capacity allocation and operation strategy.
Distributed energy storage is widely recognized as a key enabler of smart grids for its role in complementing renewable generation by smoothing out power fluctuations [56,57]. For instance, surplus energy can be stored during conditions of low demand and supplied back during periods of heavy load.
Dispatchable distributed energy storage can be used for grid control, reliability, and resiliency, thereby creating additional value for the consumer. Unlike distributed generation, the value of distributed storage is in control of the dimensions of capacity, voltage, frequency, and phase angle.
In such cases, a distributed energy storage (DES) can play an essential role in improving stability, strengthening reliability, and ensuring security. This monograph is dedicated to fundamentals and applications of energy storage in renewable microgrids.
