Research on Regulation Scheme and Stability Control Strategy for Enhancing Power Supply Capacity of End-Region Power Grid
Considering the high requirements for power supply reliability,this study focuses on addressing the limitations imposed by faults in the same tower double loop line N-2 and bus faults within the regional power grid.A second line of defense safety and stability control system strategy is developed.By simulating typical fault scenarios and considering factors such as changes in new energy output and thermal power unit start-up conditions,a comprehensive scheduling control scheme that combines pre-control measures with stability control systems is formulated.Additionally,an analysis of load transfer characteristics specific to rectifying variable loads within the electrolytic aluminum industry is conducted,leading to proposed calculation methods for prioritizing real cut-off loads and step-by-step load reduction principles suitable for end-of-grid situations.
