Cooperative Control Strategies for Multi-Terminal HVDC Systems for Enhanced Renewable Integration

High-voltage direct current (HVDC) technologies need to get better because more green energy sources are being used in power systems today. This paper discusses new joint control methods for multi-terminal HVDC (MT-HVDC) systems. The goal is to make it easier to connect green energy sources that are spread out. A strong control design that improves the system’s dependability, efficiency, and dynamic performance is at the heart of the discussion. The paper uses a decentralized control approach to look into how various converter stations can work together to make sure steadiness and the best flow of power when load conditions and production rates change. The suggested control method uses advanced communication methods and real-time data to allow for proactive and flexible reactions to changes in the grid. In addition, an in-depth examination of how the control methods affect system stability and power quality is given, showing big improvements in grid resilience. The simulation results from a set of stress tests on a scaled MT-HVDC model show that the joint control methods work to make it easy to add renewable energy sources, which solves problems with grid stability and power distribution. This study adds to the growing field of HVDC systems and shows how to make the power grid more reliable and long-lasting.
