Can battery energy storage systems support renewable DG in distribution networks?

With the rapid development of distributed generation (DG), battery energy storage systems (BESSs) will play a critical role in supporting the high penetration of renewable DG in distribution networks. The traditional dispatching approach of BESSs commonly adopts linear models with constant operational characteristics and neglects the aging cost.

What are energy storage systems?

Energy storage systems (ESSs) in the electric power networks can be provided by a variety of techniques and technologies.

Which storage technologies are suitable for employment in distribution networks?

In contrast, with the advancement of the high power and high energy density, high efficiency, environmental friendly and grid scale batteries, these devices are becoming one of the most potential storage technologies suitable for employment in the distribution networks.

What is a distribution network?

In the distribution network, the growth in distributed generation (DG) connection is resulted in to a change in behavior of the network. In the past, distribution networks were operated to carry electric power from up-stream transmission network to down-stream costumers.

What is an ESS in a distribution network?

For distribution networks, an ESS converts electrical energy from a power network, via an external interface, into a form that can be stored and converted back to electrical energy when needed , , . The electrical interface is provided by a power conversion system and is a crucial element of ESSs in distribution networks , .

Is a distribution network suitable for large and complex systems?

Nevertheless, their selection is not appropriate for large and complex system, especially in less straightforward applications, with size complications and the varied characteristics of distribution networks. They may also generate imprecise solutions for real time problems .
