Description: The PV array has been simulated at one year period and other code sources are
been discussed. In order to extract the voltage deviation from the array, we intent to
apply the formula of the MPP to these codes. Our approach, considering the hole
system, has not been totally implemented in Simulink. The grid utility and the control Platform: |

Description: At this moment, the major
obstacle of wide PV system commercialization is the
high initial investment cost that stems from the strict
grid connection standards and high expectations from
the PV system [2], [3]. The grid-connected PV system
consists of two parts: PV arrays that convert irradiation
to electrical energy, and the converter that feeds the
energy into the grid. Platform: |

Description: To keep overall output power per
unit cost low, the grid-connected converters should be
able to extract the maximum available power from the
PV arrays. Since the PV array characteristic is highly
nonlinear, maximum power point tracking (MPPT) of
the PV arrays becomes rather challenging. Platform: |

Description: This paper
presents a PSCAD/EMTDC model of PV solar panels, the grid
connected three phase voltage sourced inverter (VSI) and its
controller system. The VSI control is implemented with current
control loops. A maximum power point tracking (MPPT)
algorithm is implemented to get the maximum output power for
any given solar irradiation and temperature. This is integrated
with the inverter control in such a way that the requirement of
DC-DC converter is eliminated to harvest the maximum power.
The inverter model also maintains near unity power factor
regardless of the level of power output and maintains an
acceptable level of current harmonics. Finally, the developed
model is validated with the output of a commercially used PV
module. Platform: |

Description: “Grid Connected
PV Systems with Smart grid functionality”. It solves the problem of shading to the available
NTNU PV modules which is sensitive to the exiting central inverter system topology by
proposing a PV system which is more efficient and reliable. This thesis is focused on the
design of the PV-grid connected inverter power stage that supports the proposed PV system
under study. As part of the NTNU renewable energy laboratory project, a single phase 1kW,
230V, dual power stage inverter is designed. The important parameters required for inverter
stage including input inductance and capacitance, DC –Link capacitance and LCL filter were
designed. 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: |
