The increasing share of renewables is creating new challenges for distribution grids and operators have to adopt more and more advanced tools for the evaluation of network investments, especially for scenarios in which distributed generation is expected to drastically grow. In particular, the maximum connectable power (Hosting Capacity) as well as the benefits that Smart Grid technology can bring...
Since the last decade, distribution networks are facing a continuously growing penetration of distributed generation, mostly thanks to the “clean energy” incentives promoted by national governments. In particular, these initiatives have enhanced the presence of renewable-based generators in electricity grids. Taking advantage of their intermittent nature, the curtailment of a small portion of production...
Generation from non-programmable renewable energy sources, which is endowed with dispatching priority but is not always required to participate in ancillary services, has massively increased its share of demand supply in recent years; thus, a reduced number of large conventional power plants is left to be dispatched. Therefore, active power imbalances in AC power systems can lead to more severe frequency...
The recent increase of distributed generation in distribution networks has determined the necessity of developing new control strategies for the mitigation of power quality issues. One of these functions, considered as one of the most promising solutions for the management of voltage congestions, is represented by the droop control of DG units. The traditional Power Flow formulation often does not...
The integration of generation units in distribution grids is one of the main research topics in the field of smart grids. Governments are supporting the connection of small/medium size generators directly to the distribution network, but the consequent growing number of energy producers poses several technical issues. For the planning and operation of a distribution network it is then important to...
