Description: This paper presents the modeling and simulation of a
high-speed single-shift micro turbine generation system. This
unit has four parts: a compressor-turbine, a permanent magnet
generator, a three phases bridge rectifier and inverter. The
model is built from the dynamics of each part with their
interconnections, and two different control strategies suitable
respectively for isolated and grid-connected operation were
developed. Finally, simulation studies have been carried out
under a stepped load. The model is developed in the
MATLAB/Simulink (Matlab 2007a) and implemented in Power
system Toolboxes. This model is a useful tool for studying the
various operational aspects of micro turbines Platform: |

Description: Grid-connected distributed generation sources interfaced
with voltage source inverters (VSIs) need to be disconnected
the grid under: 1) excessive dc-link voltage 2) excessive ac
currents and 3) loss of grid-voltage synchronization. In this paper,
the control of single- and two-stage grid-connected VSIs in photovoltaic
(PV) power plants is developed to address the issue of
inverter disconnecting under various grid faults. Inverter control
incorporates reactive power support in the case of voltage sags
based on the grid codes’ (GCs) requirements to ride-through the
faults and support the grid voltages. A case study of a 1-MW
system simulated in MATLAB/Simulink software is used to illustrate
the proposed control. Problems that may occur during grid
faults along with associated remedies are discussed. The results
presented illustrate the capability of the system to ride-through
different types of grid faults.-Grid-connected distributed generation sources interfaced

Description: In this paper, an efficient active power filter (APF) scheme is developed to estimate and compensate for harmonic distortion in an electrical power network. The developed APF control scheme is based on a double proportional feedback controller and a single-phase voltage-source half-wave bridge inverter. The proposed filter uses a Multi-layer Artificial Neural Network (MLANN) with a shift method for estimating system harmonic currents and voltages at a dedicated point. The proposed scheme is tested on a 13 bus industrial distribution system. The obtained results ensure the effectiveness of the proposed filter. The system is simulated in MATLAB-Simulink and simulation results prove that the polluting harmonics have been greatly reduced. Platform: |

Description: This code presents a single-phase, single-stage
current source inverter (CSI) based photovoltaic system (PV)
for grid connection. A double-tuned parallel resonant circuit is
designed to attenuate the second- and fourth- order harmonics
at the inverter dc side. It helps to improve the power quality and
system efficiency. A modified carrier based modulation
technique for the current source inverter is studied to magnetize
the dc-link inductor and to control the switching pattern for the
single phase grid-connected CSI. The operation of Single Phase
Transformer-less grid connected PV system is verified by the
simulation using MATLAB/Simulink software. The results are
analyzed and presented. Platform: |
