Microgrid-Grid Resynchronisation
Systems
A fault occurring on a distribution line can cause circuit breakers to trip , and the microgrid to switch from grid-connected mode to islanded mode . The resynchronisation system sends measurements from the main grid to the microgrid , specifically when microgrids are separated from a weak part of the main grid , to allow the breakers to be closed and the microgrid to be reconnected . A resynchronisation system has been developed to bring the voltage , phase and frequency of a microgrid back into alignment with the main grid in the event of a fault on the distribution line . |
Competitive Advantage • A ground-breaking system that can optimise the load by either minimising the time , or the energy needed , to resynchronise
• An innovative solution that includes microgrid interrogation to determine load diversity , the optimisation of the process of synchronisation to achieve low energy cost , or produce a rapid response
Impact • The algorithm decides which way to push the voltage amplitude , frequency and phase in order to minimise the time or the energy required to resynchronise the microgrid , based on the estimate of load and generation types
