“…Over the years, many researchers have paid their attention on the development of different storage technologies and in particular Thermal Energy Storage (TES) technologies (sensible or latent) [2]. In order to efficiently convert solar energy into generated power, Organic Rankine Cycle (ORC) systems are considered one of the most competitive at large scale [3]. Hence, many efforts have been put by academia and industry to achieve advancements with the final aim of making micro-solar CHP plants costcompetitive in the near future.…”

The operation of a power plant based on solar energy can vary significantly with time because of the intrinsic intermittency of the energy resource. Hence, a smart management is required to deal with the complex dynamic variations of the different subsystems. In order to do that, different control logics can be implemented but their effectiveness strictly depends on the temporal evolution of the parameters considered. For a given plant configuration, their exact estimation can be obtained through experimental tests during the commissioning of the plant. However, any change in the design parameters of the plant reflects in a different time constant, whose preliminary knowledge may be of support in tuning the control logic of the plant during the design stage. Therefore, based on the configuration of a small-scale concentrated solar combined heat and power plant as designed and built under the EU funded project Innova MicroSolar by several universities and companies, in this study a prediction of the time constant of several plant configurations with varying solar multiple and size of the storage tank is performed. By making use of the dynamic simulator previously developed by some of the authors, an estimation of such characteristic is assessed in case of potential redesign of the plant, providing also useful suggestions into the design of the control logic.

“…The rise of new industrial countries such as China and India, the increase in the world's population and, the advancement of science and technology, resulting in energy demand around the world is increasing slowly. Fossil fuels play the role of supplying most of the world's energy in the past century because it is cheap and convenient to use but has a bad impact on the environment such as global warming and acid rain [1].…”

Renewable energy sources such as solar heat, wind energy, geothermal, biomass and exhaust heat is one way to overcome the crisis of energy and environment in the world. Organic Rankine Cycle (ORC) is a power generation system modified from Rankine Cycle by using organic liquid with low boiling point as working fluids such as R-134a, therefore various types of heat sources can be use. This research was design and manufacture organic Rankine cycle by using R-134a as working fluid with solar collector as the source of energy. The design of this research resulted in the length of the evaporator tube is 14.5 m, length of condenser is 13.9 m and the length of solar collector tube is 9.4 m. The helical Diameter of evaporator and condenser are 250 mm, and the high of helical evaporator 290 mm and condenser 280 mm. Organic Rankine cycle system is designed to produced 534.4 Watt, but when the experiment is carried out the system generates energy of 305 Watt with the efficiency of 4.30%
