The influence of charging/discharging efficiencies and lifetime on the best allocation storage capacity and the annual revenue of wind-storage coupled system is analyzed. Table 6 presents the optimal storage capacity under different charging and discharging efficiencies and lifetime.
The optimal energy storage capacity and the corresponding annual revenue of wind-storage system increase when increasing the charging and discharging efficiencies and decreasing the energy storage system cost. The optimal storage capacity is 38MWh when the charging and discharging efficiencies are 95%, the energy storage cost is 150 $/kWh.
In (Khalili et al., 2017), Proposed a capacity determination method for grid-scale energy storage systems (ESSs), using the exchange market algorithm (EMA) algorithm, the results show the ability of the EMA in finding the global optimum point of the storage and their hourly charging rate.
Energy storage system optimal capacity and annual revenue versus cost As shown in Fig. 8 and Table 5, the efficiencies for charging and discharging are set to be 85%, and the influence of the energy storage cost and lifetime on the optimal installation capacity and annual income is analyzed.
As shown in Fig. 9 and Table 6, the cost of energy storage plant is set to be 300 $/kWh. The influence of charging/discharging efficiencies and lifetime on the best allocation storage capacity and the annual revenue of wind-storage coupled system is analyzed.
In order to make the operation timing of ESS accurate, there are three types of the relationship between the capacity and load of the PV energy storage system: Power of a photovoltaic system is higher than load power. But this time, the capacity of ESS is less than or equal to the total demand capacity of the load at peak time;
