Can mobile energy storage systems improve resilience in post-disaster operations?

Distributed energy resources, especially mobile energy storage systems (MESS), play a crucial role in enhancing the resilience of electrical distribution networks. However, research is lacking on pre-positioning of MESS to enhance resilience, efficiency and electrical resource utilization in post-disaster operations.

Can energy storage improve power network resilience?

This is crucial for the large-scale participation of flexible resources in network resilience enhancement. Previous research has proposed various methods to enhance power network resilience. Energy storage is considered as one of the most effective solutions for enhancing the resilience of electrical power network .

Why do we need a resilient power distribution network?

In the face of the customer’s demand for high power supply reliability and high power quality, it is urgent to establish a resilient distribution network that can not only resist extreme disasters and quickly recover the power distribution system loads, but also ensure a high voltage quality of the distribution system during recovery process.

How stable is the power supply of a PDS?

With the line restoration and the coordinated dispatching of various resources, the power supply of the PDS is gradually stable at time period t = 4 − 11 h, and the average voltage offset of the power supply buses rapidly reduces.

How is power flow restricted in a resilience scenario?

In resilience scenario studies, the power flow in lines is restricted by the line operation status variable ϵ i j. The Big-M method is utilized to relax the constraints for the nonlinear terms involving the multiplication of integer and continuous variables.
