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 centralized control is one of the methods proposed, also by the Italian Regulatory Authority (consultation 255/15), to integrate more renewable energy sources in the electrical networks. Due to the limited number of available measurements in the distribution system, one of the key problems for a centralized control scheme is the correct estimation of the network state. In general, the placement...
Nowadays the world energy infrastructure is subjected to a progressive transformation. In fact it is already possible to notice the growing number of distributed small generation units, based on different technologies, directly connected to the power grid. At present the energy that can be produced by the sun and wind seem to be the most promising renewable energy sources. The use of the solar energy...
