Which Deepness Class Is Suited for Modeling Power Electronics?: A Guide for Choosing the Right Model for Grid-Integration Studies

Abstract

The high implementation of renewable energy systems (RESs) and the need to increase transmission capacity across Europe (e.g., north-south Germany) have resulted in integrated power electronics (PE)-based solutions in electrical grids. PE allows more flexibility and control over power grids. Solutions such as high-voltage (HV) dc systems and flexible alternating current transmission systems (FACTS) increase energy transfer capabilities while preserving the system's safety (e.g., providing reactive power). Additionally, PE-based solutions, which are characterized by fast dynamic control actions, can support the grid during disturbances [e.g., a low-voltage ridethrough (LVRT) during faults]. These solutions are widely integrated into RES applications, where they enable maximized energy extraction from natural resources (e.g., the maximum power point tracker).
