Optimal Power Flow Implementation with MATLAB Code Examples

This article presents how to implement Optimal Power Flow (OPF) calculations using MATLAB. The OPF problem represents a crucial aspect in power system planning and operation, as it helps determine optimal operating parameters for various power system components to meet electricity demand while ensuring system stability. The article provides MATLAB code examples demonstrating solution approaches using optimization techniques like linear programming, quadratic programming, or interior-point methods. Key MATLAB functions such as fmincon from the Optimization Toolbox will be discussed for solving constrained optimization problems. Additionally, the article covers practical applications of OPF problems, including electricity market operations and power system planning scenarios. Implementation details will include bus admittance matrix formation, constraint handling for generator limits and voltage boundaries, and objective function formulation for minimum generation cost or transmission loss reduction. This content aims to provide valuable information for both power system research and practical engineering applications.
