Learn how ETAP Grid Code improves grid interconnection studies and compliance checks. This presentation provides a walkthrough of ETAP’s advanced modeling capabilities and study modules which alleviate the challenges of manual processes, including integration of rulebooks with load flow, short circuit, protective device coordination, transient stability and harmonic analysis. Interconnection studies are vital for the power sector's shift to sustainable energy, ensuring the safe, secure, and efficient operation of connected power plants. By streamlining compliance checks and ensuring that grid code requirements are met, the time-saving solution offered by ETAP offers a much-needed comprehensive solution for grid interconnection studies.

It is crucial to define the reactive power limits to evaluate the voltage support available under normal, abnormal and emergency operations with the unit's safe functioning. Published generator thermal capabilities curves, produced by the manufacturer, define the limits for safe operation based on the generator design's thermal limitations. Practically, the available reactive capability differs from the published equipment curves due to plant specific design and operating constraints. This presentation discusses a theoretical approach utilizing a simplified electrical distribution system and an ETAP model to identify and validate the plant-specific unit capability.
