摘要：
Aiming at operation of grid-connected voltage-sourced converters (VSC) under universal and dynamically varied harmonic voltage conditions existing in real power grid, this paper proposes an improved sliding-mode-based direct power control (SMC-DPC) strategy under universal harmonic grid voltage. Due to tasks to all harmonics, its implementation has no need of accurate detection of concrete order and phase position of harmonics, thus with certain engineering application potentials. Based on past researches, integral mathematic model of VSC under universal harmonic circumstances is founded, three different control objectives, i.e. sinusoidal current output, active and reactive power fluctuation eliminations, are devised and final improved SMC-DPC strategy under universal harmonic grid voltage is performed. Simulation results reveal that the improved strategy enhances VSC operating performance under universal grid harmonic voltage, contrasting to traditional SMC-DPC. © 2016, Power System Technology Press.
