consumption of natural resources.<\/span>\r\n<span style=\"color: #000000\">By means of this approach, the TES group members study different processes, with a particular focus on those related to the

Specifically, an increase of the PV cells operating temperature leads to an almost linear reduction of their performance. To overcome this issue, TES group members have developed a low-cost cooling system.<\/span>\r\n<span style=\"color: #000000\">The feasibility of the proposal has been numerically evaluated by means of a \u201cin-house\u201d mathematical model developed in Matlab Environment. Then, the real performance of the proposed system are evaluated experimentally investigated using the developed facility installed on TES Lab.<\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"col-sm-4 col-md-4 \">\r\n<div class=\"card y-move no-padding bordered\">\r\n<div class=\"col-padding-small col-padding-small-xs description-container\" data-type=\"column\">\r\n<h4 class=\"\"><span style=\"color: #000000\"><strong>Power Plant Dynamic Modelling<\/strong><\/span><\/h4>\r\n<p class=\"\"><span style=\"color: #000000\">In the current energy scenario, electricity is produced by a mix of fossil fuel power units and renewable energy power plants. After the deregulation of the energy markets and the large penetration of renewables, fossil fuel units need to be managed in a flexible way to compensate the power fluctuation related to the unpredictability of renewable energy plants like wind and solar. This means fossil fuel power plants able to start-up, shut down or change the load in a couple of minutes or even seconds. Obviously, strong load changes require, on the one hand, high ramp rates and, on the other hand, produce thermal and mechanical stresses which reduce devices\u2019 lifespan.\r\nTo detect the most stressed components and compute their life reduction, the most powerful instrument is the DYNAMIC ANALYSIS.\r\n<\/span>\r\n<span style=\"color: #000000\">In TES group, fossil fuel units and renewables power plants are modelled in OPEN MODELICA Language with the aim of testing start-up\/shut down procedures and maximum tolerable ramp rates. Using simulation results, the life reduction of the most stressed component is computed using an \u201cin house\u201d procedure called \u201cLifeTime Estimation Procedure\u201d (LTE). Using the LTE procedure, it is possible to develop new and more reliable management strategies characterised by power plant components reduce lifetime reduction.<\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"col-sm-4 col-md-4 \">\r\n<div class=\"card y-move no-padding bordered\">\r\n<div class=\"col-padding-small col-padding-small-xs description-container\" data-type=\"column\">\r\n<h4 class=\"\"><span style=\"color: #000000\"><strong>Design Optimisation, Part-load Behaviour and Dynamic Performance Prediction of Waste Heat Recovery Units<\/strong><\/span><\/h4>\r\n<p class=\"\"><span style=\"color: #000000\">Waste Heat Recovery Units like Organic Rankine Cycles, Air Bottoming Cycles, Steam Rankine Cycles, etc. are powerful cycles able to increase the energy efficiency of industrial processes.\r\nIn TES group, two \u201cin-house\u201d codes have been developed to design these types of units using Matlab Environment. Based on the Optimisation results, the most performing fluids and plant configurations are tested in ASPEN and DYMOLA Environments to predict part-load and dynamic performance. The best configuration is then analysed from an economic and an exergetic point of view.<\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Research activities Extension of the hydraulic turbines operating range to provide electrical power system flexibility &amp; stability for the integration of renewable.
