Abstract:
This study aims to develop a hydro-thermal model and simulation code of solar ORC (Organic Rankin Cycle) system, and to predict capable efficiency of energy conversion from solar to electrical and thermal energy for a regional feasibility study. Solar ORC system is one of solar power systems including photovoltaic power generation. The hydro-thermal performance of solar ORC system should be addressed for operating conditions with environment variables, working fluids and mechanical components including solar collector, expander, generator, pump, condenser, ducting, refrigerant storage tank, etc. Recent researches have focused on the system configuration, design point simulation and the suitability of various working fluids. However, the system performance strongly depends on operating conditions, especially the ambient temperature and amount of the solar radiation. In our literature review, the available energy efficiency with operating scenario under regional specific conditions has not been fully studied. We are developing a model of solar ORC system and an in-house simulation code for various classes of solar ORC system, for various working fluids, and for different mechanical components. In the seminar, the hydro-thermal model of solar ORC system and simulation results under various regional daily and annual environmental conditions will be presented. The simulation result includes available electrical and thermal energy efficiencies.
