Optimized Integration of Hybrid Renewable Sources with Long‐Life Battery Energy Storage in Microgrids for Peak Power Shaving and Demand Side Management under Different Tariff Scenario

“…Some of the major advantages of VRFB storage over the other conventional batteries are its highest cycle life of around 13 000 (≈20 years which is close to the life of solar PV power plants) and the scalability of its power and energy capacity. [ 38,39 ] Thus, VRFB is very suitable as a storage solution for stationary renewable energy applications to ensure energy system reliability.…”

“…VRFB is scalable and has independent power and energy capacity, longest cycle life (≈13 000) which makes it one of the most suitable storage solutions for renewable energy and other stationary power system applications. [ 35,36 ] The biogas energy source acts as a reservoir or storage in the form of biogas inside the biodigester and therefore can be used to satisfy the energy demand in case of unavailability or inadequacy in solar and wind energy supply. This work demonstrates the economic viability of a microgrid for specified load profiles by scheduling the renewable energy sources, battery storage, and the distribution grid considering the impact of electricity tariff.…”

Optimizing vanadium redox flow battery system power loss using particle swarm optimization technique under different operating conditions

“…The VRFB stack size determines its power capacity, while the electrolyte volume determines the energy capacity. The high columbic efficiency, the longest cycle life (>20 000), 2 deep discharge capacity, and fast response time are all advantages of VRFB [3][4][5][6][7][8][9] storage over the other conventional battery storage solutions. Because the electrolyte used in the VRFB works as a built-in coolant as well, there is hardly a requirement of a separate heat sink unit, thus reducing the auxiliary thermal management system cost, compared to that of the Liion batteries.…”

“…VRFB has shown promising BESS performance in achieving efficient and reliable operations of renewable energy based microgrids, ranging from peak shaving to demand response management. 8,[14][15][16][17][18][19] Kerdphol et al 20 proposed Particle Swarm Optimization (PSO) method-based frequency control of the standalone microgrid to obtain optimum sizing of VRFB based BESS at a minimum total BESS cost. Further investigation by Kerdphol et al 21 proposed an optimum sizing of VRFB-based BESS using PSO incorporating dynamic demand response to mitigate the instability of microgrid during an emergency.…”

“…Charge-discharge operations of VRFB with four sets of electrolyte flow rates at three different levels of stack terminal current have been taken for validation of the proposed work. It has been observed that for a 1 kW 6kWh VRFB storage system, the overall system power loss becomes the minimum at an optimal flow rate of 6 L/min for a range of (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) L/min of electrolyte flow rate at 40, 45, and 50 A chargedischarge operations. The proposed work formulation demonstrated in this paper is a generalized one and can be very useful for maximizing the overall system efficiency of VRFB storage and ensuring the reliability of VRFB integrated power system applications.…”
