The present work is focused on the development of a simulation model for an existing cogeneration power plant, which utilizes a solar thermal field with parabolic trough solar collectors coupled to an Organic Rankine Cycle engine. The power plant is modeled in the trnsys v.17 software package and its performance has been validated with real operating conditions. The simulated system (concentrated solar power (CSP) field and ORC engine) is the main part of a hybrid power plant located near “Ziloti” village of the Municipality of Xanthi, in northeastern Greece. The construction of the hybrid power plant was funded by the Strategic Co-Funded Project of the European Territorial Cooperation Program Greece–Bulgaria 2007–2013 with the acronym ENERGEIA. The power plant simulated in this paper includes a 234 kWth solar parabolic trough collector (PTC) field, a 5 m3 thermal energy storage tank, and a 5 kWe ORC engine for the production of thermal and electrical energies. The results of the simulations present small deviation in contrast to the real operating data of the CSP power plant coupled with the ORC engine, therefore the simulation model is considered as reliable.

An assessment of the energy efficiency of a hybrid solar-geothermal power plant is performed taking into account the geothermal resource of one of the productive well (TD4) and the direct normal irradiance at Tendaho geothermal site in Ethiopia. A thermodynamic model of a single-flash geothermal plant integrated with a parabolic trough concentrated solar power system is developed to estimate the energy production in a hybrid solar-geothermal power plant. In the hybrid power plant, the parabolic trough concentrated solar power system is employed to superheat the geothermal steam in order to gain more energy before it expands in the turbine. Thermodynamic analysis, based on the principles of mass and energy conservation, was performed to assess the efficiency of the hybrid power plant at the given conditions of Tendaho geothermal site. A figure of merit analysis was also employed to evaluate whether a hybrid power plant could produce more power than two stand-alone power plants namely the solar and geothermal power plants that constitute the hybrid power plant. Results showed that the hybrid power plant technically outperformed the two stand-alone power plants. By integrating the two energy resources, the hybrid power plant proved to generate 7158 kW of electricity which is larger than the sum of the two stand-alone power plants (geothermal and solar).

This paper proposes the reliability index of wind-solar hybrid power plants using the expected energy not supplied method. The location of this research is wind-solar hybrid power plants Pantai Baru, Bantul, Special Region of Yogyakarta, Indonesia. The method to determine the reliability of the power plant is the expected energy not supplied (EENS) method. This analysis used hybrid plant operational data in 2018. The results of the analysis have been done on the Pantai Baru hybrid power plant about reliability for electric power systems with EENS. The results of this study can be concluded that based on the load duration curve, loads have a load more than the operating kW of the system that is 99 kW. In contrast, the total power contained in the Pantai Baru hybrid power plant is 90 kW. This fact makes the system forced to release the load. The reliability index of the power system in the initial conditions, it produces an EENS value in 2018, resulting in a total value of 2,512% or 449 kW. The EENS value still does not meet the standards set by the National Electricity Market (NEM), which is <0.002% per year. Based on this data, it can be said that the reliability of the New Coast hybrid power generation system in 2018 is in the unreliable category.
