Emergency control measures against long term voltage instability

March 12, 2024

The conference, held in Manchester from 4-7 March 2024, brought the entire industry together under one roof. DPSP offers attendees the chance to learn, keep up to date, network with new and existing colleagues, and tackle challenges facing the industry both now and in the future. As one of the only conferences dedicated solely to power system protection, DPSP it is a must-attend for anyone in the industry.

As the world moves towards decarbonisation, the modern grid is facing new challenges and uncertainties. With the increased penetration of renewables, a diverse range of generation types, and the wider distribution of generation sources, the power system must adapt to keep up.

This shift towards clean energy is a positive step towards a sustainable future, but it also requires careful planning and management. As we face these new challenges, it’s important to continue investing in innovative solutions that can help us build a more resilient grid.

Vasia’s paper on Emergency Control Measures Against Long-Term Voltage Instability sheds light on the critical issue of voltage collapse in power systems. The paper presents a comprehensive analysis of various emergency control measures, including load tap changer control and load shedding techniques, to prevent system collapse.

The study’s sensitivity analyses on Zone 3 trip margins of distance relays relative to load powers provide valuable insights into the most effective load shedding strategies to pre-empt critical relay operations. The paper’s simulation results using the Hellenic Interconnected System model demonstrate the efficacy of the proposed emergency control measures.

Overall, Vasia’s research is a significant contribution to the field of power systems engineering. Her work provides a valuable resource for professionals seeking to prevent voltage instability and system collapse.

By working together and leveraging the latest technologies, we can ensure that the power system is ready to meet the demands of the future. Let’s embrace the opportunities presented by this transition and build a cleaner, more sustainable energy system for all.
