Breakthrough approaches in multi-area load frequency control: enhancing reliability in modern power systems
Year: 2024
Type: article
Abstract: This study focuses on applying Model Predictive Control (MPC) for Multi-Area Load Frequency Control (LFC) to enhance the stability of interconnected power systems by regulating frequency deviations and tie-line power exchanges. In a multi-area system, each region operates its own generators and faces unique load demands, leading to potential frequency imbalances and power flow issues. MPC addresses these challenges by predicting future system states, solving an optimization problem at each time step, and determining the best control actions to minimize deviations while respecting system constraints like generation limits. By anticipating disturbances, such as load fluctuations or renewable energy variability, MPC adjusts control inputs more effectively than traditional methods like Proportional-Integral (PI) controllers. The study validates the predictive frequency control model for a three-area electrical system, demonstrating MPC's capability to improve system response times, handle constraints, and ensure reliable, efficient operation in modern grids, particularly as renewable energy sources increase.
