“…Although most of the articles reviewed share a common approach for yield assessment and economic analysis, several details emerge when discussing optimization routines, as well as the approach for solving thermal inertia, among other concerns. According to Hirsch (2017), financing of large infrastructure such as CSP plants requires a detailed risk analysis that, if proper engineering, procurement, and construction (EPC), and operation and maintenance (O&M) contracts are carefully prepared with reliable suppliers, they remain centered around financial and yield uncertainties. Technical yield assessment aims to provide investors with a reliable probability of energy yield and revenues that, coupled with the analysis of the investment and O&M costs, enables a solid financial evaluation.…”

Concentrated solar power (CSP) technologies have been developed over the past four decades for commercial operation, establishing them as reliable power generation sources in regions with high direct solar irradiance. The sizing of the solar field, thermal energy storage systems, and power block enables CSP plants to operate under various operating conditions, while also exhibiting capabilities to generate multiple products such as electricity, heat, desalination, and cooling.The limitations of CSP systems can be reduced by utilizing the positive traits of other technologies, thus resulting in hybrid plant configurations that can fully exploit different technology strengths while minimizing their individual weaknesses. This review presents the state of the art on CSP stand-alone plants for both power generation and combined generation of different products. Subsequently, the characteristics of CSP plants hybridized with photovoltaics, wind, fossil fuels, and biomass systems are discussed for both power multiple-product generation. The review of assessment methodologies provides suggestions for both assessment and performance analysis and comparison with other generation technologies. This review shows that hybrid CSP plants have clear advantages in terms of cost, flexibility of operation, adaptability, and capability for the multigeneration of different products compared with stand-alone plants used to generate each product individually. Hybrid CSP plants have advantages and can be designed to satisfy multiple demands on a case-by-case basis and are valid alternatives to combinations of stand-alone plants.

“…For this study, models based on [25] for the PV field, battery storage, and electric heater components were used. The modeling of the parabolic trough field and the thermal energy storage system is based on [26]. For the heat pump and the power block, stationary models were created in EBSILON ® Professional.…”

Concentrated solar power (CSP)—photovoltaic (PV) hybrid power plants allow for the generation of cheap electrical energy with a high capacity factor (CF). A deep integration of both technologies offers synergies, using parts of the PV generated electricity for heating the thermal storage tank of the CSP unit. Such configurations have been previously studied for systems coupled by an electric resistance heater (ERH). In this work, the coupling of a CSP and a PV plant using a heat pump (HP) was analyzed due to the higher efficiency of heat pumps. The heat pump is used as a booster to lift the salt temperature in the storage system from 383 to 565 °C in order to reach higher turbine efficiency. A techno-economic analysis of the system was performed using the levelized cost of electricity (LCOE), the capacity factor and nighttime electricity fraction as variables for the representation. The CSP–PV hybrid with a booster heat pump was compared with other technologies such as a CSP–PV hybrid plant coupled by an electric heater, a standalone parabolic trough plant (PT), a photovoltaic system with battery storage (PV–BESS), and a PV thermal power plant (PVTP) consisting of a PV plant with an electric heater, thermal energy storage (TES) and a power block (PB).

“…However, depending on the thickness and thermal conductivity of the material, high heat transfer resistances sometimes occur in the solid. In order to consider this heat transfer in the storage bed itself and to develop a compact formulation of the heat balance equations, simplifications are made, which can be taken from, e.g., [19].…”

For conventional power plants, the integration of thermal energy storage opens up a promising opportunity to meet future technical requirements in terms of flexibility while at the same time improving cost-effectiveness. In the FLEXI- TES joint project, the flexibilization of coal-fired steam power plants by integrating thermal energy storage (TES) into the power plant process is being investigated. In the concept phase at the beginning of the research project, various storage integration concepts were developed and evaluated. Finally, three lead concepts with different storage technologies and integration points in the power plant were identified. By means of stationary system simulations, the changes of net power output during charging and discharging as well as different storage efficiencies were calculated. Depending on the concept and the operating strategy, a reduction of the minimum load by up to 4% of the net capacity during charging and a load increase by up to 5% of the net capacity during discharging are possible. Storage efficiencies of up to 80% can be achieved.
