A soft-switching inverter topology (the Class Φ) is presented which draws dc source current through a transmission line or a lumped-network approximation of a distributed line. By aligning the inverter switching frequency just below the line’s λ/4-wave resonance, the Class Φ topology enforces oddand even-harmonic content in its drain voltage and input current, respectively. The symmetrizing act...
By increasing the penetration level of the inverter-based distributed generations (IBDGs) in power system, their fault ride through capability has become one of the essential issues of the new grid codes. This paper proposes a novel method to limit inverter fault currents which are used in DGs. To achieve FRT, interface-inverter operates as a controlled voltage source during normal operation as...
This paper proposes the Modified Switched Inductor Quasi Z Source Inverter (MSL-QZSI) for extracting maximum solar power generation. The Z source inverter uses LC impedance network to couple the main converter circuit to the power source, which provides the boosting of input voltage. It is not possible in traditional voltage-source inverter (VSI) and current-source inverter (CSI). The proposed ...
Microgrid (MG) bridges different inverter interfaced distributed energy resources (DERs) to operate and control efficiently within a grid. The multi-master-slave strategy can provide robust of DERs in close proximity. role master is significant synchronising the slave reducing effect single unit failure. However, faulty side communication failure also suddenly affect synchronisation DERs. Unfor...
The massive expansion of Distributed Energy Resources and schedulable loads have forced a variation generation, transmission, final usage electricity towards the paradigm Smart Communities microgrids Renewable Communities. In paper, use multiple DC for residential applications, i.e., nanogrids, in order to compose create renewable energy community, is hypothesized. Bus Signaling distributed con...
Distributed Control of Inverter-Based Power Grids
Transformerless topologies are widely preferred to use in the grid connected photovoltaic (PV) generation system due to higher efficiency, lower cost and lower weight in comparison with other topologies employing transformer. In this paper, switching losses is minimized by incorporating Zero Voltage Switching (ZVS) in a full-bridge topology, at switch turn-on and an adaptive Variable dead-time ...
Nowadays renewable energy sources are essential to meet the real power demand. All the Distributed Energy Resources are connected to the common grid through three phase Voltage Source Inverter (VSI). The reliable operation of microgrid can be achieved by controlling three phase voltage source inverter. Voltage and frequency of the Distributed Energy Resources are continuously varying and they d...
