“…Aside of the PV technology, in terms of solar power technology, solar thermal power plant has also become a growing option [11], [18], [19]. The solar thermal technology utilizes the sun radiation to heat a fluid, which then produces steam; the steam will later be used to run the turbine in order to create electricity power.…”

Abstract-The high average solar radiation in Indonesia makes solar power plant an option to improve renewable energy-based electricity generation in the country. Currently in Indonesia, the photovoltaic (PV) plant has been more widely implemented, and several extensive researches on solar thermal plant have been carried out. In this paper, a comparative study on the 20-MW on-grid solar thermal and photovoltaic (PV) power plant is committed to measure the cost competitiveness of the technologies in Rongkop district, Indonesia; which is recently considered as the center for solar power plant in Indonesia. The simulation follows two installed energy capacity scenarios by the International Energy Agency and is committed up to year 2030, in accordance with the target year of United Nations' Sustainable Development Goals.By using System Advisor Model it is shown that a 20-MW solar thermal power plant equipped with 6-hour storage is able to produce slightly higher annual energy output than the solar PV plant design of similar capacity. However, the levelized cost of electricity (LCOE) values of both solar thermal plants with no storage and 6-hour storage significantly exceed the LCOE of PV plant throughout the years of simulation. This implies that in Rongkop, Indonesia the PV plant is a more economically competitive solar power plant technology to be implemented until 2030, compared to the solar thermal plant.

Summary Solar thermal electricity generating technology is an alternative solution to energy crises and environmental problems, which has caused wide concern in recent decades. In this paper, a molten salt parabolic trough‐based concentrated organic Rankine cycle system is proposed and investigated. A quadribasic nitrate salt with low melting temperature is employed as a heat transfer and storage medium. A stable heat transfer and economic model is established with Matlab. The radial and axial temperature distributions in the collector tube are obtained, and the impact of condensation and evaporation temperatures on the heat transfer area is analyzed. Results show that the temperature along the axial direction linearly increases, and the temperature at the collector tube exit decreases with the increase of molten salt mass flow rate. The maximum temperature difference along the radial direction of the collector tube happens in the annular gap. Heat transfer and thermodymanic analysis indicates that condensation temperature has a more evident effect on heat transfer area than that of evaporation temperature. An increase in condensation temperature leads to a decrease in the evaporator area, the condenser area increases, and the total area decreases. Economic analysis indicates the collector cost plays a predominant role in total capital costs, and decreasing molten salt mass flow rate can considerably reduce collector cost. Levelized energy cost sensitivity analysis indicated that operation time per year has a more evident effect than that of the four factors. Heat transfer and economic analysis on the system helps in the selection of operation parameters.

“…Such systems are especially attractive for isolated regions (Pikra et al, 2013). Usually, the small size solar power systems are coupled to concentrating solar collectors and ORC with volumetric expanders (Hoffschmidt et al, 2012;Kane et al, 2003).…”

Abstract:The paper presents an innovative prototype of a solar power plant, purposely designed for small-scale applications such as residential and/or small commercial buildings. The system consists of 10 kW e Organic Rankine Cycle (ORC) plant and innovative solar thermal collectors. In particular, 235 m 2 of flat-plate evacuated solar collectors are designed to heat diathermic oil up to 180°C. A variable volume pump is managed by a feedback controller in order to obtain the desired outlet set point temperature for the different weather/load conditions. The hot diathermic oil passes through a storage tank, which is adopted with the purpose to reduce the oscillations due to the solar radiation variability. By means of the tank, a better exploitation of solar energy is also achieved, reducing the time-shift between production and demand. For achieving a constant ORC inlet temperature the tank outlet hot diathermic oil passes through a gas-fired burner, which provides auxiliary additional thermal energy. Therefore, the ORC simultaneously produces electrical energy and low temperature (45°C) cogeneration heat. This solar power plant was dynamically simulated in TRNSYS environment. The simulation tool includes a novel model in order to simulate the dynamic thermal behavior of solar collectors, whereas the ORC dynamic was simulated by means of a performance data map provided by the manufacturer. The model also includes a tool for the calculation of energy and economic parameters and the evaluation of the optimum thermoeconomic configuration. Results indicated that the best pay-back period is obtained for a solar field area of about 200 m 2 and a solar fraction of about 75%. Nevertheless, the system may be competitive from the economic point of view only if incentives can be made available, as commonly occurs for renewable applications, i.e., solar systems. This prototypal system aims to become a potential solar power system for small residential and/or commercial buildings. The presented study will be suitably used as a basis for the installation of a working prototype in located Naples, Italy.
