Constrained optimised flexible power control for grid‐connected converters under unbalanced faults

نویسندگان

چکیده

This paper presents a constrained multi-objective optimisation scheme for grid-connected voltage source converter operating under unbalanced conditions in three-phase three-wire system. The is aimed at evaluating the reference currents required to supply all power generated by connected grid, whilst simultaneously suppressing oscillations of both real and reactive powers. trade-off between these two conflicting requirements achieved setting single cost function with variable weightings. Two constraints are set restrict instantaneous phase current maintain low DC-bus percentage ripple. A genetic algorithm applied search optimal solution. Simulation results presented confirm effectiveness proposed method.

Flexible Power Electronic Transformer for Power Flow Control Applications

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...

A model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy

Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
