“…In addition, there are several different chemistries in the Li-ion battery family, in which NMC batteries and LFP batteries account for a large share of the installed capacity of ESSs and electric vehicles. Although LFP batteries are inferior to NMC batteries in terms of energy density, LFP batteries offer advantages in terms of their lifetime and safety [32]. Therefore, the HESSs that respectively include the NMC battery and the LFP battery are investigated to estimate the battery lifetimes.…”

By combining the advantages of different energy storage technologies, the hybrid energy storage system (HESS) can satisfy the multiple requirements of prosumer systems. However, the required capacity of the HESS is larger than that of the single-battery energy storage system (ESS). This paper investigates the energy exchange within the HESS caused by the phase shift of the low-pass filter controller and its relevant impact on the HESS. The results show that unnecessary energy exchange results in an oversized capacity and increased energy loss. In addition, the increase in the time constant of the low-pass filter controller leads to a larger phase shift, further contributing to the increases in the total capacity and energy loss. Furthermore, this paper compares the single-battery ESS, the battery-supercapacitor HESS, and the battery-flywheel HESS implemented in a household-prosumer system along with a renewable energy source (RES). The comparison of the ESS combinations demonstrates the differences between their power flows, the required capacities of their individual energy storage devices (ESDs), their energy losses, their battery lifetimes, and their project costs. The results indicate that techno-economic analysis should be performed carefully to select the appropriate ESS solution for specific household-prosumer systems.

“…The evolution of electric systems has led to development of electric microgrids, defined as a collection of distributed generators and loads placed within a demarcated border. A microgrid can operate in either grid-connected or islanded mode [1], [2]. At a lower power scale, some authors have introduced the concept of residential microgrids or nanogrids, conceived as microgrids connected at a single point of common coupling, located in a low voltage distribution grid.…”

“…At a lower power scale, some authors have introduced the concept of residential microgrids or nanogrids, conceived as microgrids connected at a single point of common coupling, located in a low voltage distribution grid. A residential microgrid can come up by limiting its electric boundary to a single house with a capacity range of 2 -20 kW [1], [3], [4].…”

Context:This paper presents a comparative study of the performance of three topologies for interconnecting Lithium ion batteries and supercapacitors in a hybrid energy storage system for use in electric residential microgrids with intermittent generation. The hybrid system’s main purpose is to prolong battery life, using the supercapacitor to handle the dynamic component of current from a pulsed current load. This work builds upon a preliminary simulation-based study, in which two semi-active topologies were compared and evaluated. Here, we add an active topology to the study and describe the operational benefits of each topology. Method:For every topology in this study, a non-isolated half-bridge bidirectional DC converter was used, and a proportional–integral (PI) double-loop linear ACC control algorithm was designed for controlling the converters. In the active topology an additional optimisation-based real-time frequencydecoupling control strategy was employed. Results:A parallel active topology allows better management of stored energy in the SC by supporting variation of SC terminal voltages with a DC converter as interface to the DC bus. Conclusions: Semi-active topologies are easier to design and control, but the operational benefits of supercapacitors require voltage variation at the terminals. This variation is made possible with an active topology.
