“…To the author's knowledge, there are currently only two commercial operating CSP-PV power plants, one located in Chile [3] and the other one developed in collaboration with ENEA in Sicily [1]. However, none of these plants features a high level of integration even if several studies published in the open literature investigated hybrid and technology-integrated CSP-PV solutions [4].…”

“…In this work, a mixed-integer linear programming (MILP) approach was developed to tackle the optimization problem of a highly integrated hybrid CSP-PV plant. The present work is part of the collaboration between the Polytechnic University of Milan and ENEA, which for many years has been active in developing CSPbased projects in southern Italy [1][2] and, in general, Mediterranean regions.…”

“…For the lower cycle turbine inlet temperature (550°C), the traditional steam Rankine cycle is considered and modelled in Thermoflex in design and off design conditions [24]. The power block layout and its performance at design conditions (nominal cycle efficiency) are assumed from the characteristics of a real plant [25], located in Partanna (Sicily), already modelled in a previous work regarding small scale CSP plant in Italy [26]. The second power cycle considered for turbine maximum temperatures of 550°C is a sCO2 cycle adopting the recompression layout, proposed in figure 3.…”

“…The steam Rankine cycle performance at design conditions, as already anticipated in Section 2.3, are taken from the previous work [26] and refers to a real plant located in Partanna (Sicily), Italy [25]. Regarding the sCO2 cycles instead, their performances are evaluated through the methodology presented in Section 2.3 considering the main parameters reported in table 6.…”

This work investigates performances and costs of various configurations of 5 MWel solar tower CSP plants, located in Sicily. The design of the plants aims at comparing two solar towers concepts (i.e., a single tower and modular towers), both adopting billboard receivers. A sensitivity on various heat transfer fluids (i.e., solar salt and sodium), storage fluids (solar salt and NaCl-MgCl2) and power block technologies (i.e., steam Rankine and sCO2 cycles) is also proposed. For each investigated plant configuration, tailored numerical models are presented to assess the performances of each plant subsystem (e.g., solar field, receiver, piping system, power cycle). The results show very competitive LCOE (between 160 and 180 $/MWhel), achievable with satisfactory capacity factors (around 55%), while suggesting good profitability levels for such investments in small scale CSP plants.

Application of Phase Change Material and Artificial Neural Networks for Smoothing of Heat Flux Fluctuations

et al. 2021

The paper presents an innovative method for smoothing fluctuations of heat flux, using the thermal energy storage unit (TES Unit) with phase change material and Artificial Neural Networks (ANN) control. The research was carried out on a pilot large-scale installation, of which the main component was the TES Unit with a heat capacity of 500 MJ. The main challenge was to smooth the heat flux fluctuations, resulting from variable heat source operation. For this purpose, a molten salt phase change material was used, for which melting occurs at nearly constant temperature. To enhance the smoothing effect, a classical control system based on PID controllers was supported by ANN. The TES Unit was supplied with steam at a constant temperature and variable mass flow rate, while a discharging side was cooled with water at constant mass flow rate. It was indicated that the operation of the TES Unit in the phase change temperature range allows to smooth the heat flux fluctuations by 56%. The tests have also shown that the application of artificial neural networks increases the smoothing effect by 84%.
