Tangent Approximation Method for Multi-Objective Reactive Power Optimization in IEEE 14-Bus Power System

This paper presents the application of the tangent approximation method to address the multi-objective reactive power optimization problem in the IEEE 14-bus power system. The optimization objectives focus on maximizing the total reactive power output from generators while simultaneously minimizing network power losses. Through systematic optimization of the power system parameters, we enhance generator reactive power capabilities and reduce transmission losses. The implementation typically involves power flow calculations using Newton-Raphson method, constraint handling for voltage limits, and gradient-based optimization techniques. This approach enables more effective power system management and optimization, leading to improved energy utilization efficiency and reduced energy consumption. Key algorithmic components include Jacobian matrix computation for sensitivity analysis and penalty function methods for handling operational constraints.
