A New Single-phase Symmetrical Cascade Multilevel Inverter with Low Number of Power Switches

In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

Reactive Power Sharing and Harmonic Voltage Modification in Single Phase Island Micro-Grid with Drop Control

Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of...

Optimal Locating and Sizing of Unified Power Quality Conditioner- phase Angle Control for Reactive Power Compensation in Radial Distribution Network with Wind Generation

In this article, a multi-objective planning is demonstrated for reactive power compensation in radial distribution networks with wind generation via unified power quality conditioner (UPQC). UPQC model, based on phase angle control (PAC), is used. In presented method, optimal locating of UPQC-PAC is done by simultaneous minimizing of objective functions such as: grid power loss, percentage of n...

Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

A Three-Phase Active Power Filter for Harmonic and Reactive; Power Compensation

In this paper, a 3-phase active power filter (APF) is presented to eliminate harmonics and to compensate the reactive power of an uncontrolled rectifier with capacitive loading taken as non-linear load. An APF is realized using 3-phase voltage source inverter (VSI) with dc bus capacitor. Reference source currents are estimated using P-I control over dc bus voltage and 3-phase source voltages. C...
