Free QuoteIn this paper, a hierarchical energy management strategy, which can be applied to different scenarios with and without limited communication systems, has been proposed to coordinate a large number of small-scale energy storage systems to regulate frequency for power systems.
A hierarchical energy management strategy (EMS) for a fuel cell (FC)-supercapacitor (SC)‑lithium battery hybrid energy storage system (HESS), based on a fractional-order sliding mode controller (FOSMC), is proposed to address the nonlinear behavior of low-voltage direct current (DC) microgrid HESS.
This paper proposes a hierarchical sizing method and a power distribution strategy of a hybrid energy storage system for plug-in hybrid electric vehicles (PHEVs), aiming to reduce both the energy consumption and battery degradation cost.
The rule-based energy management strategy is proposed in Ref. for a battery/SC hybrid energy storage system to generate the battery current reference in a robust fractional-order sliding-mode control, with hardware-in-the-loop (HIL) to test the efficacy of the proposed control scheme.
Hybrid energy storage system has nonlinear characteristics. A layered energy management method for hybrid energy storage system is proposed. Energy management strategy of device layer based on FOSMC is proposed. More stable bus voltage and faster response compared with sliding mode controller.
Conclusions In this paper, a hierarchical frequency regulation strategy was proposed for enhancing the resilience of power systems by regulating system frequency. In the recovery stage, the power systems are coupled with communication systems.
