The overall theme of my ongoing research is the use of non-wire alternatives to increase transfer capacity in the electric power system. The focus is on actively managing thermal and voltage constraints on all voltage levels using distributed energy resources, such as converter-based generators and battery energy storage systems. With development of robust control algorithms, the transfer capacity of existing lines and other network components can be maximised by a safe reduction of operational margins. In turn, this defers the need for network reinforcement, and allows for faster expansion of renewables.
