0. Introduction. A renewable energy-based power system is gradually developing in the power industry to achieve carbon peaking and neutrality [1].This system requires the participation of energy storage systems (ESSs), which can be either fixed, such as energy storage power stations, or mobile, such as electric vehicles.
For the three energy storage operation modes, with the increase in energy storage power, the optimal values of the effectiveness of the heat exchanger, the maximum pressure ratio of the GSC and the heat distribution ratio do not change significantly, and they largely stabilize at approximately 0.929, 120, and 0.45, respectively.
Sizing and operation modes for energy storage and demand-side resources and an architectural scheme are presented. Net present value for all technological options are compared to aid the selection of the best option. 2.2.4 Island mode operation with energy storage. In the case of storage, the independent installation of a battery
