A Design with Implementation of Solar and Thermal Hybrid Power Plant

In this master thesis a hybrid photovoltaic / solar thermal power plant was modeled for a high irradiance location. The selected location was Chiles northern region. For the evaluation the software greenius was used, a program being continuously developed at DLR since 1999. This program did not possess a storage function for PV simulations. Therefore one of the aims of this thesis was firstly to analyze the accuracy of the PV model and subsequently develop and implement a battery model to evaluate the financial viability of standalone PV systems. For this reason the greenius model was compared with PVWatts and PVSyst photovoltaic models. Additionally, an electric storage element based on a charge balance model was implemented in the system. This model proved to accurately depict the performance of batteries without the need for many parameters. The second aim of this thesis was to optimize and evaluate the financial feasibility of hybrid power plants with a high capacity factor (> 90%).
