Grid-Forming Technology as Solution to Improve Voltage Stability: A Case-Study on the Italian Transmission System

Abstract

The paper presents the application of the gridforming technology as solution to improve the voltage stability of the system following a critical contingency. A simplified pseudo model of the Italian transmission system is taken as reference case. The model is simulated under the assumptions of a theoretical forward-looking scenario, where a severe contingency would lead to critical conditions for the system. The results indicate the benefit of the grid-forming technology to effectively improve the voltage stability, thus ensuring a secure and stable operation of the system.
