Development of an Automated Framework for Testing Grid Code Compliance

Abstract

Abstract The European Network of Transmission System Operators for Electricity (ENTSOE) has designed network codes to ensure the safe operation of the European power grids. Each individual transmission system operator (TSO) has then, based on the network codes from ENTSO-E, defined grid codes that all operators connected to the power system must comply with to be allowed to stay connected. The focus of this thesis has been designing simulation tests and developing an automated testing framework to aid in the process of proving grid code compliance. The framework is developed using Energinet’s (the Danish TSO) type D wind farm connection requirements as an example. It can easily be adapted for use with any other grid codes. The framework uses simulation models built with DIgSILENT PowerFactory. A study case model was developed in PowerFactory to represent a wind farm containing 12 wind turbines with a total rated power of 30 MW and a connection voltage of 220 kV. The framework has then been able to successfully conduct and run load flow calculations and dynamic RMS (Root Mean Square) simulations to identify both compliance and non-compliance with grid code requirements for the study case wind farm.
