“…These types of batteries are also free from self‐discharge problem as the electrolytes are reserved in separate chambers according to the availability of space . In addition, the RFBs have a flexible design and full discharge capability, fast charging by replacing exhaust electrolyte, controllable cell temperature, straightforward scaling, long life enabled by easy electrolyte replacement, and low‐temperature operation …”

“…The careful control of the electrolyte temperature is also essential to evade solution precipitation below 15 °C and above 35 °C . This battery also consists of moving mechanical parts (i.e., pumping systems) and also requires management of pumps, flow, and power . In addition, RFB needs costly ion‐exchange membrane that can contribute more than 40% of the overall battery cost.…”

“…24,25 The redox flow batteries (RFBs) as an ESS have recently demonstrated their ability to maintain the load frequency control (LFC), enhance power quality, and overcome other operational problems faced by modern power systems. This type of battery has many benefits over other energy storage batteries such as large capacity, high energy density, easy to transport, ease of recycling, fast charging by replacing exhaust electrolyte, and controllable cell temperature, 26,27 which make it more appropriate for various applications of modern power system. [28][29][30] Other large-scale energy management technologies (ie, pumped hydro and compressed air storage) are restrained by the suitability of the terrain, whereas RFBs batteries can be easily installed and distributed in suburban areas.…”

Summary Growing electricity demand, environmental issues, and challenge to decrease dependence on fossil fuel resources have increased the inception of wind generation into the power system. However, higher penetration of wind‐based generating units into the existing grid can affect the working of the power system. Traditionally, a wind unit does not provide inertia, but collectively, wind units can have a notable impact on the dynamic performance of the power system. However, the battery energy storage systems have the potential to offer flexibility and ancillary supports to the power system. This article evaluates the impact of redox flow battery (RFB) in coordination with a doubly fed induction generator (DFIG)–based wind turbine unit (WTU) to enrich the dynamic performances of a multi‐source interconnected power system in a deregulated electricity market. The modified inertial control scheme is proposed for the DFIG unit that responds in the event of frequency deviation in the grid. The turbine sheds its kinetic energy and provides active power injection, thereby enhancing the frequency response of the system. The recently developed moth‐flame optimization (MFO) algorithm is employed for optimal tuning of the proportional‐integral (PI) controller and the speed regulator of a DFIG‐WTU. The simulation studies have been executed to analyze the impact of the RFB with WTU on the system frequency, tie‐line and different generating units power through a comparative study in terms of the settling time, and peak overshoot/undershoot in a deregulated electricity market. The analysis reveals that the WTU effectively contributes to sustaining the frequency and tie‐line power oscillations during abrupt load disturbances in the proposed power system. Moreover, the inclusion of RFB in coordination with the WTU helps to reduce the stress on a wind turbine during inertial control scheme. It can also reduce wind curtailments by absorbing excess power flowing through transmission lines, reduces wastage of green energy, and gives better dynamic response under different operating conditions of the deregulated electricity market.

“…The excessive reliance on finite fossil fuels (coal, petroleum, natural gas) is a non-sustainable practice that causes irreversible damage to the environment. [1,2] Developing alternative energy sources such as wind, solar, waves, and tidal energy, has minimized fossil fuel consumption and reduced greenhouse gas emissions. To efficiently utilize these intermittent renewable resources, researchers have developed new energy storage technologies, among which the lithium-ion battery (LIB) is the dominant type used in modern consumer electronics and electric vehicles (EVs).…”

Dual‐carbon batteries (DCBs) are a promising candidate for smart grid applications, owing to their low cost, high power capability, and environmentally friendly benefits. As an essential component of DCBs, electrolytes not only act as a medium for ion migration during the running of the battery, but also provide active ions to be intercalated into carbon electrodes, exerting significant impacts on the electrochemical performance and safety of the DCB. In this Review, we discuss recent progress in electrolyte research for DCBs, including conventional liquid electrolytes, highly concentrated electrolytes, and gel polymer electrolytes, with a focus on their stability and compatibility with carbon electrodes. Finally, we present perspectives on the current limitations and future research directions of electrolytes for DCBs. Some recommendations for battery evaluation are also offered.

Summary This paper investigates the operation of various optimised AC‐coupled hybrid power systems for an isolated community in South Australia. In addition to diesel generators, various combinations of distributed generators and storage technologies are considered to form different hybrid power systems. Optimal design of the hybrid power systems is implemented using particle swarm optimisation (PSO) algorithm. The performance of the PSO in optimizing the above hybrid systems is discussed in detail. Whilst meeting the power system operational constraints, the minimum levelised cost of electricity (LCOE) of all systems, with various combinations of system components, are calculated. Simulation results obtained for each optimized system are carefully described and analysed. The annual operations of various components in each system are then compared and discussed in detail. A sensitivity analysis by varying the cost of wind turbines and the photovoltaic is also conducted for all hybrid systems. It has been found that the inclusion of energy storage systems (battery and flywheel) can reduce the LCOE and CO2 emission significantly compared to the inclusion of renewable generations (solar and wind) alone. The diesel‐wind‐solar‐battery system is the eco‐friendliest with an annual CO2 emission of 451 t compared to the reference diesel system (1064 t). In addition, the hybrid system consisting of diesel, wind, solar, battery and flywheel is found to be the most economic with a LCOE of 58.94 ¢/kWh compared to the diesel system with a LCOE of 67.17 ¢/kWh.
