Summary
This paper investigates the impact of replacing synchronous generators with inverter-based resources (IBRs) on voltage fluctuations and flicker levels in transmission systems.
Read more Read lessUnderstanding these effects is crucial for utilities to anticipate the implications of future renewable resource integration on voltage quality for transmission-connected customers and ensure compliance with grid code requirements, particularly regarding flicker severity levels.
To conduct this assessment, a test system has been developed, comprising four different scenarios with a synchronous generator, an inverter-based photovoltaic resource, a highly and rapidly varying electric arc furnace load, and various mitigation strategies. Simulations are performed, aiming to explore the impact of replacing synchronous generator units with equivalent-sized PV plants in each scenario. The primary objective is to analyze the resulting impacts on voltage quality and flicker levels in the transmission system, as well as for loads directly connected to the grid, and to propose potential mitigation approaches.
