The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
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.
When the system is at time t, the system total power generation output can be expressed as:(1) P G (t) = {P P V (t) − P E S (t) (Energy storage charging) P P V (t) + P E S (t) (Energy storage discharge)
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;
Specifically, the energy storage power is 11.18 kW, the energy storage capacity is 13.01 kWh, the installed photovoltaic power is 2789.3 kW, the annual photovoltaic power generation hours are 2552.3 h, and the daily electricity purchase cost of the PV-storage combined system is 11.77 $. 3.3.2. Analysis of the influence of income type on economy
According to the capacity optimization configuration, it can be seen that the power purchase cost of the system has been greatly reduced, accounting for only 1.64% of the total cost. This is due to the increase in the two parts of the peak electricity purchase cost and energy storage offset by the increase of the PV system.
