Taking two energy storage units j and k as an example, after the maximum power output for a time of Tmax, the following can be obtained: (14) E b j E a j P j = T max E b k E a k P k = T max where Pj and Pk are the rated power of the unit j and k, respectively.
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.
Therefore, the target energy of each storage unit can be expressed as (17) E b n = E p n = E sum P load T b P n P sum where the subscript p denotes the proportional distribution and Psum is the sum of the rated power of all units.
To improve the carrying capacity of the distributed energy storage system, fast state of charge (SOC) balancing control strategies based on reference voltage scheduling (RVSF) function and power command iterative calculation (PIC) are proposed in this paper, respectively.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
