The operational flexibility of coal-fired power plants (CFPPs) should be effectively enhanced to accommodate large-scale photovoltaic and wind power within the power grid. The integration of thermal energy storage (TES) systems is a potential way to enlarge the load-cycling range of CFPPs.
Energy storage technologies offer a viable solution to provide better flexibility against load fluctuations and reduce the carbon footprint of coal-fired power plants by minimizing exergy losses, thereby achieving better energy efficiency.
This paper focuses on the possibility of retrofitting coal-fired power plants (CFPPs) and converting these to grid-side energy storage systems (ESSs). It proposes a sizing and scheduling co-optimisation model to investigate the energy arbitrage profitability of such systems.
The maximum equivalent round-trip efficiency of the proposed system is 50.81%. The minimum payback period is 13.5 years. To accommodate high penetration of intermittent renewable power, including wind power and photovoltaic power, coal-fired power plants (CFPPs) are forced to enhance operational flexibility.
Coal-fired power plants integrated with P2H and thermal energy storage were proposed. The operational flexibility of the integrated system is determined. Exergy destructions and flows within the proposed systems are calculated. The maximum equivalent round-trip efficiency of the proposed system is 50.81%. The minimum payback period is 13.5 years.
The retrofitted energy storage system is more cost-effective than batteries for energy arbitrage. In the context of global decarbonisation, retrofitting existing coal-fired power plants (CFPPs) is an essential pathway to achieving sustainable transition of power systems.
