Integration and Control of Heterogeneous Power Sources in Meshed Distribution Grids

With the advent of low-voltage microgrids, wind farms and photovoltaic power stations, the management of medium-voltage distribution grids must face new challenges, since uncoordinated operation of the various power sources may cause excess power flows, under-and over-voltages, unwanted tripping of protections, and unexpected distribution losses. This paper proposes a general and scalable approach to the integrated control of distributed power sources in meshed distribution grids. The main goal is to minimize the power losses and the voltage deviations at grid nodes, by taking advantage of all the controllable entities.
