Different from the extant power flow analysis methods, this paper discusses flows for unified quality conditioner (UPQC) in three-phase four-wire systems point of view impedance matching. To end, combined with designed control strategies, establishing method UPQC model is presented, and on basis, system can be equivalent to an adjustable model. After that, a concept matching introduced into stu...

Model Predictive Control (MPC) provides various advantages over traditional controllers in power electronics applications. However, reducing the complexity and computational burden of Finite-control set-model predictive control (FCS-MPC) multi-leg multilevel inverters is still a challenging task. In this paper, simplified model direct (MPDPC) for three-level, four-leg grid-connected converter (...

The unbalanced current drawn by the composite loads in small-scale industries is mainly due to single-phase loads. Any operation of will cause unbalance and produce distortion non-linear neutral increased voltage at load end reduced an increase linear Industries find it difficult balance control current. To overcome problem, this work aims add a passive network different configurations along wi...

Low Voltage Distribution Grids (LVDGs) become highly unbalanced due to the advent of single-phase solar PV plants. As a result, voltage and current levels neutral conductor show significant increase. Therefore, monitoring entire state network is essential. However, existing estimation algorithms estimate states phase conductors while ignoring conductor. This paper presents novel approach comple...

Single-loop current sensorless control allows for abolishing of the instantaneous measurement in system using only a single loop with voltage feedback to stabilise DC-bus voltage. This approach eliminates sensors circuit, benefiting from saving space on printed circuit board and minimising power dissipation circuitry. paper focuses single-loop applied bidirectional three-phase four-wire three-l...

The droop-based control schemes are widely used for power-sharing and of the isolated microgrids. conventional droop scheme with inner current voltage controllers can work effectively under ideal voltage. However, existence unbalance tends its performance to worsen. This paper aims propose an enhanced method improve power-sharing, maintain distributed generators’ (DGs) terminal voltages system ...
