A magnetic model dedicated to the stability of the power grid

International audienceTo address the abysmal lack of efficiency of the electrical system (73% of losses, 45% of worldwide CO2 emissions), an energy-efficientdescription of electromagnetism lying on a reversible interpretation of the Faraday's law is described. Space-consolidation and time-reconciliation of all the scales involved in the management of the power system are derived from this framework. At the upper space-scale, a simplified descriptionof the grid based on the Kuramoto's model is proved to be suitable for assessing the stability of the synchronous state of a power system. Hence, acoherent approach for long-term power systems analysis is proposed and demonstrated in the case of the French Reunion island
