Resilient interconnected microgrids (IMGs) with energy storage as integrated with local distribution networks for railway infrastructures

This paper is aiming to development and design of Interconnected Microgrids (IMGs) with effective strategies for integrated energy storage and hybrid Distributed Energy Resources (DERs) with the distribution lines so that it can store energy in the off peak for re-use during the day. One potential application is the integration with the railway infrastructures as a new green technology. This goal will be achieved by proposing heuristic technique to enable interconnected MGs to work transparently with the recent energy storage. Railway transportation MG model is proposed to balance energy flows between trains moving and braking energy, energy storage system and a main power utility network. The paper proposes an energy optimization tool for the interconnected railway-MG system. Artificial Bee Colony Algorithm (ABC) is applied for achieving the economical cost during the operation. Digital simulation scenario has been validated by real data; the achieved results show the impact and effectiveness of the proposed strategies.
