Integration of energy storage to improve utilisation of distribution networks with active network management schemes

Active Network Management (ANM) has been developed over the past decade in the UK as a potential solution to facilitate integration of Distributed Generation (DG) in distribution networks. It is used to manage network limits and allows significantly cheaper and faster connections for DGs, compared to the network reinforcement. However, ANM can help with the DG penetration only to a certain extent as new DG connections in constrained networks will result in curtailment. This paper investigates the levels of energy storage and locations of its placement in reducing curtailment of DGs and improving utilisation of distribution networks with ANM solutions. It evaluates and compares energy storage values of energy storage capacity at different locations, and using the real network and wind data provided by SP Energy Networks (SPEN) Accelerating Renewable Connection (ARC) project
