Harmonic Assessment Based Adjusted Current Total Harmonic Distortion
The Journal of Engineering, 2016 Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency‐dependency of the resistances should be taken into account, so that the apparent power and the power factor have to ...

Harmonic Currents of Finite Energy and Laminations [PDF]
GAFA Geometric And Functional Analysis, 2004 We introduce, on a complex Kahler manifold (M,\omega), a notion of energy for harmonic currents of bidegree (1,1). This allows us to define $\int T \wedge T \wedge \omega^{k-2},$ for positive harmonic currents.

Harmonic Current Suppression Strategy for Grid-Connected PWM Converters With LCL Filters
IEEE Access, 2019 As for a grid-connected PWM converter with LCL filter, harmonic current can flow freely into the grid-side inductor and filter capacitor, when the connected power grid is harmonically distorted. The fact lies in that the conventional control scheme has a
