Keywords: water shortage optimization algorithm smart water meter water distribution network energy efficiency water losses Pumped Storage Hydropower Solar-hydro hybridization

The research activity concerns pressurized water systems and is developed in two lines: water distribution systems and hydroelectric plants.


In the context of water distribution systems, the topics addressed concern numerical modeling and application of optimization algorithms for the design and sectorization of water distribution networks, water energy efficiency and water-energy nexus; advanced analysis of monitoring data from smart meters aimed at estimating water losses and aspects related to water quality. Furthermore, the research activity is aimed at defining methodologies for the long-term planning of water distribution systems, resilience assessment and its variation with respect to climate and socio-economic change scenarios.


In the context of hydroelectric plants, the topics addressed concern Pumped Storage Hydropower (PSH) and the hybridization of hydropower plants with photovoltaic systems, in order to evaluate the benefits in terms of hydroelectric production, environmental impact and water resource recovery. The research activity was also dedicated to the analysis of run-of-the-river hydropower plants in relation to hydroelectric production scenarios.
