A New Perspective of Wind Power Grid Codes Under Unbalanced and Distorted Grid Conditions [PDF]
IEEE Access, 2020 Increasing penetration of wind power has led power system operators worldwide to develop new grid codes for integration of a wind power plant (WPP) onto the grid. According to the grid codes issued by Federal Energy Regulatory Commission (FERC) in the US, a WPP must have low voltage ride through (LVRT) capability, power factor design criteria, and ...

Improved DPC Strategy of Grid-connected Inverters under Unbalanced and Harmonic Grid Conditions [PDF]
Journal of international Conference on Electrical Machines and Systems, 2013 This paper presents an improved direct power control (DPC) strategy for grid-connected voltage source inverter (VSI) under unbalanced and harmonic grid voltage conditions. Based on the mathematic model of VSI with the negative sequence, 5th and 7th harmonic voltage components consideration, a PI controller is used in the proposed DPC strategy to ...
