Customer ServiceExtensive efforts have been made on the utilization of the energy storage system with the different energy storage technologies in the HPS [16, 17]. Jiang et al. proposed a unified mathematical model to optimize the configuration of the BESS with multiple types of batteries, in which the fixed power supply and demand curves are adopted.
While the optimal configuration of the ESSs does not have particularly strict requirements for calculating time, it is still appreciated for enhancing computational efficiency. For obtaining the objective function, the hybrid GWO-PSO outperforms the GWO in the 118-node system, and it is inferior to the GWO in the 33-node system.
Assess the impacts of the proposed approach on the system resilience considering the multi-faults' development. Introducing energy storage systems (ESSs) into active distribution networks (ADNs) has attracted increasing attention due to the ability to smooth power fluctuations and improve resilience against fault disturbances.
Due to the reasonable coordination control of distributed generators (DGs) and energy storage systems (ESSs), ADNs can provide favorable power supply flexibility and satisfy local load consumption more effectively [, , ].
Furthermore, the effects of the power supply and demand on the configuration of the BESS with multiple types of batteries can be investigated. The model P2 is superior to the model P1 in two aspects.
The optimal computation rarely explores the clustering of typical N-1 and N-2 fault scenarios of ADNs. Further research is required to determine the quantitative impact of the optimal configuration of the ESSs on the resilience of ADNs while considering a multi-factor resilience evaluation and fault development patterns.
