Design Optimization of Utility-Scale PV and Storage Hybrid Plants

This document, authored by Dr. Mahesh Morjaria of Terabase Energy, provides a comprehensive overview of utility-scale photovoltaic (PV) and storage hybrid plant design optimization. It covers key components including PV modules (thin-film, poly-crystalline, mono-crystalline), mounting systems (fixed tilt and tracking), DC and AC electrical design, inverters, transformers, and substations. The course outline details utility-scale PV plant architecture, from sunlight conversion to grid delivery, emphasizing balance of system (BOS) costs and efficiency. Real-world examples like Agua Caliente, Topaz, Desert Sunlight, and Al Kharsaah illustrate large-scale implementations. Technical aspects such as module IV curves, irradiance and temperature impacts, string configurations, and trunk bus wiring are explained. The document highlights the importance of plant SCADA and control systems for real-time monitoring, performance optimization, and grid integration, aiming to enhance energy yield and reduce costs in hybrid PV-storage plants.
