“…where subscript s indicates the CSP plant index and the subscript t is the time index; P CSP s,t , P PV s,t , P TESd s,t , and P TESc s,t represent the output power of the s-th CSP plant, the solar input power of the s-th CSP plant, TES discharging and charging power at the s-th CSP plant at time t, respectively; T is the number of time periods; N CSP is the number of CSP plants. Moreover, heat input is determined by the power block and the thermodynamic power cycle efficiency, which gives Equation (2). Meanwhile, the HFT system cannot be connected to a TES system if the HFT does not provide a higher output temperature than the allowable minimum temperature, and thus heat is not transferred to storage [37][38][39].…”
