Abstract

Hybridization of Photovoltaics (PV) and Concentrated Solar Power (CSP) together with Thermal Energy Storage (TES) has been known as a cost-effective solution for on-demand solar power generation with high flexibility and dispatchability. By integrating an Electrical Heater (EH) as a Power-to-Heat (P2H) unit in PV-CSP power plants, a more efficient hybridization can be attained. The operation optimization of such hybrid systems was investigated in this study by deploying a so-called Solar Plant Optimization Tool (SPOT). SPOT simulates the entire system quasi-dynamically and time-dependent, calculates the daily and annual yield of the system, and optimizes the levelized cost of electricity (LCOE) depending on the system configuration considering the operation strategies and Time of Delivery Factors (TOD) for a chosen location and available weather data. Two different operation strategies were applied for the optimization of the coupled configuration with EH, and the results were compared with the optimized co-located hybrid system as the benchmark (BM) model.
