Understanding the real-time transient/dynamic behavior of the Solar and BESS plants is important to address the technical challenges such as grid interconnections, protections, stability, and power quality issues. The course is designed to expose the participants to the modeling of inverters, develop a plant level model and perform grid interconnection studies. The focus shall be on building a plant-level simulation model using different components such as inverter, plant controller, infinite grid, load, transmission lines, transformers, and shunt devices.
