This paper discusses the challenge of optimally utilizing a finite energy storage reserve for peak shaving. The Energy Storage System (ESS) owner aims to reduce the maximum peak load as much as possible while preventing the ESS from being discharged too rapidly (resulting in an undesired power peak).
To mitigate the severe energy consumption conflict of “surplus electricity with concurrent heat energy deficit” in CHP for cold regions, it is possible to apply a solar-driven AHP system for heating peak shaving. This approach flexibly meets building heat demands while utilizing waste heat from power plants.
