ETAP combines extensive modeling capabilities with advanced solution algorithms enabling you to undertake a wide range of studies required for grid connection and grid impact analysis of wind parks, PV generation, and other renewable energy power plants. Recurring tasks can easily be automated using etapPY™ scripting tools to streamline the analysis.
ETAP Grid Code Compliance is an analysis module designed to evaluate compliance with utility grid code requirements. The application includes automated harmonic analysis for detailed power quality assessment report demonstrating that the generation facility is designed to comply with the applicable harmonic limits.
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.
The variable nature of renewable energy introduces power quality concerns, including frequency and voltage control, that may negatively impact the reliable performance of a power system. Grid codes, interconnection, or evacuation criteria must be followed during the proposed system design and continue to maintain compliance under grid-connected operation. ETAP Grid Code is a model-driven solution that includes software tools and control hardware to ensure local grid codes or standards compliance throughout the power system design and operations lifecycle.
