Design of A Single-Phase Transformerless Grid-Connected PV Inverter Considering Reduced Leakage Current and LVRT Grid Codes [PDF]
Journal of Operation and Automation in Power Engineering, 2021 A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (

Reactive Power Dispatch Method in Wind Farms to Improve the Lifetime of Power Converter Considering Wake Effect [PDF]
, 2017 In Wind Farms (WF), the most popular and commonly implemented active power control method is the Maximum Power Point Tracking (MPPT). Due to the wake effect, the upstream Wind Turbine (WT) in WFs has more active power generation than the downstream WT at

Reactive power capability of WECS based on matrix converter
Electronics Letters, 2008 The reactive power capability of a variable speed wind energy conversion system (WECS), based on an induction generator fed by a matrix converter is presented. A simplified analysis is performed neglecting the system losses. It is demonstrated that the maximum reactive power that can be supplied to the grid is ∼40% of the nominal power.
