Firstly, an uncertainty model for wind, photovoltaic, and electro-hydrogen load predictions in the park is established. Secondly, with the total investment cost as the objective
The current status of hybrid energy storage systems was summarized from the aspects of system modeling, hybrid energy storage mechanisms, design optimization, and operation dispatching.

The investment cost of the storage systems includes both energy and power costs. Additionally, to assess the environmental benefits of the planning optimization and operation optimization proposed in this paper, it is necessary to calculate the carbon emissions of the electricity consumed by the system.
With the techno-economic parameters shown in Table 1, assuming a maximum load of 10 MW and no upper limit on equipment capacities, the average cost of electricity in the industrial park after optimization using the proposed model is 0.5783 (CNY/kWh), which is 23.09 % lower than using only grid electricity (0.7522 CNY/kWh).
(1) represents the objective function, where the operational average energy cost for the park is calculated by dividing the total cost by the total electricity consumption. As each time slice has an interval, the quantity of electricity is calculated by multiplying the ten-minute average power by time interval.
Sun et al. analyzes the benefits for photovoltaic-energy storage-charging station (PV-ES-CS), showing that locations with high nighttime electricity loads and daytime consumption matching PV generation, such as hospitals, maximize benefits, while residential areas have the lowest.
