This paper analyses the thermodynamic performance and operational strategy of a molten salt thermal energy storage (TES) system coupled with a coal-fired power plant. The proposed configuration uses molten salt to store thermal energy during periods of low electricity demand and release it later to support steam generation and electricity production. The study develops a thermodynamic model of the integrated system and evaluates different operational strategies to optimise plant performance and flexibility. Results show that integrating molten salt storage can improve load regulation capability, enhance operational efficiency, and allow coal-fired power plants to operate more flexibly in power systems with increasing shares of variable renewable energy.
