Energy storage is a technology that stores energy for use in power generation, heating, and cooling applications at a later time using various methods and storage mediums. Through the storage of excess energy and subsequent usage when needed, energy storage technologies can assist in maintaining a balance between
Our recent article in IEEE Power and Energy Magazine offered a basic roadmap for establishing a predictive maintenance approach for a BESS. This approach relies on the identification of possible indicator-fault relationships during the design phase (for example, via a failure mode and effects analysis) and seeking new relationships via
Adding energy storage equipment to the system combined electric and thermal is a common trend in recent research. Aiming at the problem of source-load incoordination of combined heat and power, Teng et al.
