With the critical economic and technical factors (i.e., the levelized cost of energy (LCOE) and loss of load supply probability (LPSP)) taken into account, the capacity optimization models of a stand-alone HRES, respectively, coupled with a battery, hydrogen and thermal energy storage system are proposed.
In this paper, a volume calculation method is proposed, which can not only meet the requirements of testing, but also minimize the volume of source storage tank and recovery tank, minimize the amount of hydrogen that is used in test, reduce the cost of storage tanks and hydrogen, and improve system safety.
The energy storage system (ESS) is utilized to regulate the power output of renewable energy system (RES) to match the load demand, which is composed of the battery, hydrogen energy storage system (HESS) and thermal energy storage system (TESS), respectively (that correspond to the devices labeled as NO. 1, 2 and 3 in Fig. 1).
The thermal energy storage system (TESS) is mainly composed of electric heater (EH), thermal energy storage tank (TEST) and power block (PB). When the power output of renewable energy system is larger than the load demand, the excess energy will be converted into thermal energy by the electric heater and stored in the TEST.
The optimal volumes for source-and recovery tanks were determined by a thermodynamic analysis calculation. The sum of pressure drops in each level of the source tanks is used to evaluate the test energy consumption. The energy consumption of the system is minimized by optimizing the pressure combinations at each stage.
