Simulation-based Validation of Harmonic-constrained Optimal Power Flow

In modern grids, the increasing penetration of renewable sources requires the integration of power electronic converters. However, the nonlinear characteristics of those converters will introduce voltage and current harmonics, which decrease power quality, overload transformers, cause vibrations in generators and motors, and increase grid losses. Therefore, it is necessary to analyze power system models with harmonics. In this thesis, optimal power flow with constraints on total voltage harmonic distortion is simulated. OpenDSS is used to validate the solution of harmonic-constrained optimal power flow. Numerical tests on two IEEE feeder systems demonstrate the accuracy of the approach.M.A.S
