During discharge of the TES-CFPP system, the heat stored in the molten salt enters the turbine system, thereby generating more output power. As shown in Fig. 3, the DEA outlet feed water was partially diverted to MSH2 for heat exchange with the molten salt flowing from the hot tank (HT), and the cooled molten salt entered the cold tank (CT) …

The retirement of Coal-fired Power Plants (CFPPs) during the "carbon neutral" process leads to a reduction in the level of inertia of the power system. Battery energy storage system (BESS) can provide virtual inertia support for the system due to its fast response capability. Therefore, a collaborative planning of CFPPs'' retirement and BESS …
