Control and Filter Design of Three-Phase Inverters for High Power Quality Grid Connection
The trend toward using inverters in distributed generation systems and micro-grids has raised the importance of achieving low-distortion, high-quality power export from inverters. Both switching frequency effects and pre-existing grid voltage distortion can contribute to poor power quality. A well designed filter can attenuate switching frequency components but has an impact on the control band...
متن کاملDroop Control of Parallel Inverters with LCL Filter and Active Damping in Stand-alone Operation
-Because of the acute shortage of conventional energy resources, renewable energy harness is gaining attention. Voltage source inverter forms the interface to feed the power from the renewable source to utility. In order to increase the modularity of the system, the use of several parallel inverters of reduced rating is preferred. An effective control strategy to maintain the amplitude and freq...
متن کاملDesign of a Four-Branch LCL-Type Grid-Connecting Interface for a Three-Phase, Four-Leg Active Power Filter
Compared with the three-phase, two-split-capacitor active power filter (3P2C-APF), the three-phase, four-leg active power filter (3P4L-APF) has been widely used in three-phase, four-wire grid utility for power quality control due to its numerous advantages, such as higher current output capability, particularly in phase N, lower current and easier voltage control on the DC-side. However, design...

متن کاملActive Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads
Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...
