Harmonic Optimal Power Flow considering Harmonic Coupling Factors

as the installation scale of distributed generations in the distribution network continues to increase, the distribution network has more flexible scheduling resources. However, a large number of power electronic devices in distributed power generations pose a threat to the power quality of the distribution network. Based on the frequency coupling matrix, a harmonic optimal power flow model considering harmonic coupling factors is established. Using the method of convex relaxation, the original non-convex model is transformed into a semi-definite programming model that can be solved by mature planning software. An actual township distribution network example is used to verify the rationality of the model proposed.
