Abstract

With the increase of the distributed generation, the development of distribution networks able to operate detached from the bulk grid has become possible. However, these islanded distribution networks lead to several issues to be dealt with, including the stability, the efficient generation profile scheduling and the procurement of balancing services. This paper proposes an optimal network management scheme capable of obtaining the power profiles of all users connected to the network for a given time frame. This scheme, based on a double negotiation phase, aims to minimize the social cost for the coverage of the overall demand, keeping the network within its technical operating limits. The impact of Multi-Energy Storage Systems (MESS) in the cost of providing these services is assessed by considering the technical limits of the specific users. Finally, the proposed control scheme has been tested on four different scenarios, with increasing MESS penetration level, demonstrating to be able to reduce the social cost associated with the re-dispatching by exploiting the services offered by the Battery and Thermal Energy Storage Systems.
