Mitigation of the Voltage Imbalance of a Three Phase System by Power Injection from a Décentralisés Source

EasyChair Preprint 7576

Abstract

In three-phase systems, when the voltages are unbalanced, negative-sequence voltages and currents appear, which can increase the apparent power supplied by the network and the network losses. Load compensation at the load bus is an effective method to eliminate undesired sequence currents. This paper presents another control technique for three-phase power systems injected to a main grid to instantaneously mitigate the unbalanced voltages. In this paper we will dissect the power controller of a PV system grid connected. The proposed control approach depends on instantaneous voltages on the point of common connection and the power available in the decentralized, without utilizing line current sensors. The proposed PVS inverter current control approach is then assessed regarding only PCC voltage. To understand the proposed method and demonstrate its validity, a three-phase linear system connected to an infinite power network with unbalanced voltages. The MATLAB/SIMULINK diagram shows the viability of the proposed control.
