Exploring MCR+ technology in reactive power management and voltage control in power grids

With the rapid development and widespread integration of renewable energy into the grid, fast and precise voltage control in the system has increasingly become a critical issue for power grid companies. Currently, the automatic voltage control strategies used by dispatching organizations do not include MCR+ devices. The existing AVC control strategies for the power grid do not include the new type of MCR+ devices. This study primarily explores the application of MCR+ (Magnetic-Controlled Reactor) technology in reactive power management and voltage control in regional grids. By thoroughly analyzing the grid structure and operational characteristics of new energy convergence areas, this paper establishes a 330kV regional automatic voltage control model incorporating MCR+ as a novel reactive power compensation device. The focus of the research is on optimizing reactive power distribution and enhancing voltage stability using MCR+ technology. Simulation methods were used to verify the performance of MCR+ under various load and generation conditions, demonstrating its potential in improving the grid's dynamic response and stability. The results indicate that MCR+ technology can effectively balance reactive loads and reduce voltage fluctuations, especially in scenarios with high penetration of renewable energy sources. This study provides a new perspective and technological means for reactive power management and voltage control in regional grids, offering important references for achieving more efficient and reliable grid operation.
