Distributed mobile energy storage

Can mobile energy storage systems improve power distribution system resilience?

Abstract: With the spatial flexibility exchange across the network, mobile energy storage systems (MESSs) offer promising opportunities to elevate power distribution system resilience against emergencies.

What is mobile energy storage?

Mobile energy storage (MES) has the flexibility to temporally and spatially shift energy, and the optimal configuration of MES shall significantly improve the active distribution network (ADN) operation economy and renewables consumption.

How can mobile energy storage systems be improved?

Establishing a pre-positioning method for mobile energy storage systems. Modeling flexible resources and analyzing their supply capabilities. Coordinating the operation of mobile energy storage systems with other flexible resources. Enhancing the resilience of the distribution network through bi-level optimization.

What is a mobile energy storage system (mess)?

During emergencies via a shift in the produced energy, mobile energy storage systems (MESSs) can store excess energy on an island, and then use it in another location without sufficient energy supply and at another time , which provides high flexibility for distribution system operators to make disaster recovery decisions .

How do mobile energy storage systems work?

Mobile energy storage systems work coordination with other resources. Regulation and control methods of resources generate a bilevel optimization model. Resilience of distribution network is enhanced through bilevel optimization. Optimized solutions can reduce load loss and voltage offset of distribution network.

Are energy storage systems economic configurations in distribution networks?

However, the probability of a large-scale failure in the distribution network caused by a natural disaster is low, and the cost of the energy storage configuration is still relatively expensive. Therefore, many scholars have studied the economic configuration of energy storage systems in distribution networks.
