“…The full charge/discharge of BSS is not recommended because it results in fast degradation of BSSs. 73 In this regard, the following constraints (22 and 23) are considered in the day-ahead operation of BSSs. 25 The SOC level during any time interval is calculated according to (24).…”

Purpose Storage systems are deemed to be unable to provide revenue commensurate with the resources invested in them, thus discouraging their incorporation within power networks. In prosumer microgrids, storage systems can provide revenue from reduced grid consumption, energy arbitraging or when serving as back-up power. This study aims to examine stacking these revenue streams with the aim of making storage systems financially viable for inclusion in prosumer microgrids. Design/methodology/approach With the aim of reducing self-consumption and maximising revenue, the prosumer microgrid incorporating hybrid energy storage systems (HESS) and solar PV power is solved using the CPLEX solver of the Advanced Interactive Multidimensional Modeling Software (AIMMS). The financial analysis of the results is carried out to provide the payback periods of different system configurations of the prosumer microgrid. Findings The findings reveal that the payback period of the three HESS when minimising grid expenses during self-consumption alone and when compared with stacked revenue streams shows an improvement from 4.8–11.2 years to 2.4–6.6 years. With stacked HESS revenues, the supercapacitor-lithium ion battery HESS gave the shortest payback period of 2.31 years when solar PV power is at 75% penetration level. Originality/value Existing literature has considered revenue streams of storage systems at the electrical power transmission and distribution levels, but not for prosumer microgrids in particular. This study has captured these benefits and verified the profitability of stacking revenue from HESS to prosumer microgrids, using a case study.

“…In [29], the authors have determined the optimal size of HESS elements for keeping supply-demand balance in an islanded MG with renewable energies. Azizat O. et al have determined the size and cost of PSHESS for minimizing the MG operational cost in islanded mode [30]. The control strategy for the utilization of a battery-SC HESS is to reduce fast power regulations on the battery by using the SC and the battery for fast and slow power regulations, respectively.…”

“…The control strategy for the utilization of a battery-SC HESS is to reduce fast power regulations on the battery by using the SC and the battery for fast and slow power regulations, respectively. However, the works in [29,30], have concurrently used the SC and the battery for both fast and slow power regulations, which is against the rationale behind the hybridization of the battery with SC. Moreover, the authors of [29,30] have not performed frequency regulation studies to calculate the needed power rating of the HESSs for MG islanded operation.…”

Moreover, the authors of [29,30] have not performed frequency regulation studies to calculate the needed power rating of the HESSs for MG islanded operation. The most important advancement of this work is the consideration of the capability of LIBs to perform microcycles for fast power regulations, which is not realized in previous studies like [24,29,30].…”

Among various storage technologies used for the energy storage systems, the supercapacitors, the Pb-acid Batteries (PABs) and the lithium Batteries (LBs) are widely used for microgrid applications. The supercapacitors with highpower density are suitable for fast power regulations; conversely, the PABs have high-energy density, which makes them suitable for long-term energy management. Since the PABs and the supercapacitor can complement each other deficiencies, their combination as a hybrid energy storage system is used. However, the LB has both high-energy and high-power densities. Therefore, an LB ESS (LBESS) can similarly function like a Pb-acid batterysupercapacitor hybrid ESS (PSHESS). However, their topologies, life cycles and costs are different. This paper tends to determine which one is technically and economically more suitable for applications in islanded microgrids.For this purpose, a frequency control and energy management scheme is proposed. It maintains the balance between demand and supply, and also keeps the microgrid frequency within safe operational limits using the least needed sizes for the energy storage systems. Using the simulation results, the sizes and costs of the energy storage systems are determined. For a decade of operation, the PSHESS imposes almost 49.2% more cost than the LBESS which makes the LBESS more cost-effective.
