Real Time Closed-loop Test Rig for Decentralized Control of Smart Distribution Networks

Abstract

Electric power grids are moving towards Smart Grids and many new energy sources and loads are being integrated into distribution networks requiring the network to become more active and smart. The distribution networks have not been designed to cope with new constraints set up by the new energy sources and complex loads and will result in a number of adverse impacts. There is a considerable need for developing new algorithmic solutions for decentralised control within distribution networks and validating them at laboratory level before they can be successfully applied in the power grid. This research work addresses the development of a real time test rig which provides a decentralised control environment in distribution networks, onto which data management and network control functions are able to be implemented in a closed loop fashion, to observe their performance. This work also describes the development of a substation network controller; a platform that provides a closed loop test system for research, development, testing and validation of real time distribution network management and control functions.
