Optimal Solar District Cooling Harvesting Scenarios
Abstract
In the Southern European countries solar thermal energy is harvested few moths per year as heating, thus, solar cooling is a suitable option to increase the yield of solar fields that supports tri-generation power plants. In this kind of facilities solar cooling integration is achieved with the use of absorption chillers and appropriated energy generation management strategies. These strategies depend on the resource availability, primary energy price and energy storage facilities. Sizing these generation systems or planning modifications on existing ones, requires detailed studies and deep knowledge on the particular boundary conditions of the site and the possible scenarios that the power plant can be subjected at. In this work a comparison between solar system and CHP system is carried out for different repowering scenarios of an existing power plant. Different tilt angles are tried out in order to obtain the most cost-effective solution over useful life for a solar system which is size to harvest solar for cooling purposes.
