“…ORC systems are suitable to operate at part load and with variable input conditions without decreasing their efficiency drastically and allow an interesting conversion efficiency of thermal energy to electricity in the size range below 5 MW e [21,22]. The solar field has a net aperture area of about 8600 m 2 and, at nominal conditions, it produces a thermal power of about 5 MW.…”

Abstract. The fast increasing share of distributed generation from non-programmable renewable energy sources, such as the strong penetration of photovoltaic technology in the distribution networks, has generated several problems for the management and security of the whole power grid. In order to meet the challenge of a significant share of solar energy in the electricity mix, several actions aimed at increasing the grid flexibility and its hosting capacity, as well as at improving the generation programmability, need to be investigated. This paper focuses on the ongoing preliminary studies at the Ottana Solar Facility, a new experimental power plant located in Sardinia (Italy) currently under construction, which will offer the possibility to progress in the study of solar plants integration in the power grid. The facility integrates a concentrating solar power (CSP) plant, including a thermal energy storage system and an organic Rankine cycle (ORC) unit, with a concentrating photovoltaic (CPV) plant and an electrical energy storage system. The facility has the main goal to assess in real operating conditions the small scale concentrating solar power technology and to study the integration of the two technologies and the storage systems to produce programmable and controllable power profiles. A model for the CSP plant yield was developed to assess different operational strategies that significantly influence the plant yearly yield and its global economic effectiveness. In particular, precise assumptions for the ORC module start-up operation behavior, based on discussions with the manufacturers and technical datasheets, will be described. Finally, the results of the analysis of the: "solar driven", "weather forecasts" and "combined storage state of charge (SOC)/ weather forecasts" operational strategies will be presented.

Abstract. The dynamics of an off-grid power generating system, coupled to a storage unit and to household appliances, is described by means of an analytic hydrodynamic analog. Following this analogy, by noticing that the efflux rate from a leaking bucket is described, in terms of the liquid content, by Torricelli's formula, we denote as "Torricelli's smart consumer" a user being able to calibrate its energy consumption rate with respect to the energy level in the storage unit as if the hydrodynamic model would strictly apply. Simple solutions to the nonlinear dynamic problem associated to this type of smart consumer are found and generalization to other types of smart consumers are sought.

A techno-economic modelling tool has been developed to examine the feasibility of biomass combined heat and power (CHP) technologies to provide the energy and CO 2 demands of commercial horticultural glasshouses. Using the UK as a case study, energy and CO 2 demands of candidate glasshouse installations on an hourly basis are established using both measured and benchmark datasets. Modelled electrical and thermal generation profiles for a number of commercially available small-scale biomass CHP systems of rated outputs of 0.1-5MW e are also derived, and the results of their application within the modelling tool to carry out multi-parametric techno-economic analyses for various operational scenarios are presented. The impacts of both capital grant and generation tariff-based support mechanisms upon economic feasibility are investigated, along with that of variations in feedstock fuel prices. Net CO 2 reductions accruing from the implementation of biomass CHP are also assessed. Finally, technical options, marginal costs and sale tariffs for CO 2 recovery and supply are evaluated for specific scenarios. The results indicate that feasibility is very sensitive to the relationship between specific biomass CHP power:heat ratios and temporal electrical and thermal energy demand profiles, along with economic factors such as specific levels of capital and tariff-based support. With the utilisation of currently available financial support mechanisms, biomass CHP offers significant promise for realising economically viable significant CO 2 emission reductions in this sector.
