Table 2 The parameter comparisons between the ESS and the VESS
 Type | ESS model | VESS model |
|---|---|---|
 Charge and discharge power | \( {P}_{t, ch}^j \) and \( {P}_{t, dis}^j \) | Pch(t) and Pdis(t) |
 Capacity | \( {Q}_t^j \) | Ech(t) and Edis(t) |
 SOC | \( {Q}_t^j/{Q}_n^j \) | \( \frac{E_{ch}}{E_{ch}^{\mathrm{max}}} \) and \( \frac{E_{dis}}{E_{dis}^{\mathrm{max}}} \) |
 Efficiency | \( {\eta}_{ch}^{ESS} \) and \( {\eta}_{dis}^{ESS} \) | \( {\eta}_{ch}^{VESS} \) and \( {\eta}_{dis}^{VESS} \) |
