In residential micro-grids, the distributed energy resources are interfaced with the grid by electronic power processors. If these processors perform cooperatively, full exploitation of energy sources can be achieved together with distribution loss reduction and voltage stabilization. The paper shows that this is possible without central controllers, by taking advantage of the local measurement, communication and control capability. In particular, it is shown that micro-grid operation can be optimized by applying token ring control and grid mapping techniques, which only require communication capability between neighbor nodes via power line.

Abstract
In residential micro-grids, the distributed energy resources are interfaced with the grid by electronic power processors. If these processors perform cooperatively, full exploitation of energy sources can be achieved together with distribution loss reduction and voltage stabilization. The paper shows that this is possible without central controllers, by taking advantage of the local measurement, communication and control capability. In particular, it is shown that micro-grid operation can be optimized by applying token ring control and grid mapping techniques, which only require communication capability between neighbor nodes via power line.Pubblicazioni consigliate
