Electrical energy consumers, such as AC motors, can be supplied by a dual power supply consisting of a DC grid and a supercapacitor (SC) energy storage system. The efficiency of energy flow can vary depending on where the energy storage system is connected to the DC network, due to the resistance associated with transmission.
and the electrification of transportation and heating systems. As a consequence, the electrical grid sees much higher power variability than in the past, challenging its frequency and voltage regulation. Energy storage systems will be fundamental for ensuring the energy supply and the voltage power quality to customers.
This paper proposes an FESPS developed on the basis of a shared energy storage concept, which can execute the dual functions of power flow regulation and energy storage.
Multi-stage solutions In the conventional approach, which involves a single power con-version stage, the energy storage system is connected directly to the DC link of the converter (Fig. 4c). Increasing its working voltage requires larger serially-connected cell strings, leading to reductions in system-level reliability.
