“…Lithium-ion battery has a high energy density, low power density and a short cycle life. At the same time, the supercapacitor has a higher power density and a lower energy density than battery [2]. It is also can response to the fast power fluctuation and the cycle life is long.…”

The establishment of isolated microgrid including wind power, storage and seawater desalination load is of significant important to the use of renewable energy and the supply of fresh water resources in island region. A real-time simulation platform based on PXI and PC is built to test the operation and control of the isolated microgrid in this paper. The digital simulation model is introduced and the coordinated control strategy of the microgrid is discussed in detail. This strategy makes use of the controllability of seawater desalination load, coordinates supercapacitor and lithium-ion battery energy storage so as to maintain the balance and stability of the isolated microgrid. Finally, the simulation results show that the correctness and feasibility of the proposed coordinated control strategy.

“…To solve this, many researchers have proposed the methods of using batteries and SCs together in a hybrid energy storage system (HESS). Some literatures have proposed HESS control strategies in microgrids, such as using Fourier Transform to decompose the frequency information of load power to allocate load power to batteries and SCs (Mao et al, 2013); or use SC to compensate the harmonics and imbalance of battery current output to improve power quality (Zhu et al, 2014).…”

PurposeA standalone microgrid (MG) is able to use local renewable resources and reduce the loss in long distance transmission. But the single-phase device in a standalone MG can cause the voltage unbalance condition and additional power loss that reduces the cycle life of battery. This paper proposes an energy management strategy for the battery/supercapacitor (SC) hybrid energy storage system (HESS) to improve the transient performance of bus voltage under unbalanced load condition in a standalone AC microgrid (MG).Design/methodology/approachThe SC has high power density and much more cycling times than battery and thus to be controlled to absorb the transient and unbalanced active power as well as the reactive power under unbalanced condition. Under the proposed energy management design, the battery only needs to generate balanced power to balance the steady state power demand. The energy management strategy for battery/SC HESS in a standalone AC MG is validated in simulation study using PSCAD/EMTDC.FindingsThe results show that the energy management strategy of HESS maintains the bus voltage and eliminates the unbalance condition under single-phase load. In addition, with the SC to absorb the reactive power and unbalanced active power, the unnecessary power loss in battery is reduced with shown less accumulate depth of discharge and higher average efficiency.Originality/valueWith this technology, the service life of the HESS can be extended and the total cost can be reduced.

“…Vanadium-redox flow battery and superconductor improved the performance of wind turbine generator in [10]. Also, it is possible to smooth the output power of a PV microgrid using battery and superconductor [11]. Another work in [12] showed that the flywheel battery and storage battery can support each other by proper control scheme to support a DC microgrid.…”

This paper presents a model for availability analysis of standalone hybrid microgrid. The microgrid used in the study consists of wind, solar storage and diesel generator. Boolean driven Markov process is used to develop the availability of the system in the proposed method. By modifying the developed model, the relationship between the availability of the system with the fine (normal) weather and disturbed (stormy) weather durations are analyzed. Effects of different converter technologies on the availability of standalone microgrid were investigated and the results have shown that the availability of microgrid increased by 5.80 % when a storage system is added. On the other hand, the availability of standalone microgrid could be overestimated by 3.56 % when weather factor is neglected. In the same way 200, 500 and 1000 hours of disturbed weather durations reduced the availability of the system by 5.36%, 9.73% and 13.05 %, respectively. In addition, the hybrid energy storage cascade topology with a capacitor in the middle maximized the system availability.
