Design and integration of an MVDC system on a GB 33kV network

Western Power Distribution was funded through the Low Carbon Networks Fund to deliver an innovation project, Network Equilibrium [1]. A key technical method of this project was the design, testing, implementation and operation of a 33kV AC-DC-AC power electronics based "Flexible Power Link". This device enabled two previously separate and distinct networks to operate in parallel to enable load and generation on the system to be appropriately managed across the complete network, mitigating traditional network reinforcement requirements for new load and generation connections.
