A New Fuzzy Based UPFC Topology for Active Power Enhancement in an offshore Wind Farm
Keywords:FACT device, AC-DC convertor, DFIG, wind.
The stability of a power system is the ability of a
power system to restore an operating state of equilibrium for
a given initial operating condition after it has been subjected
to a physical disturbance, most of the variables of the system
being limited so that almost the entire system remains intact.
To create a MATLAB SIMULINK model of odd shore wind
energy system having power being transmitted through DC
transmission system. The first model will have no power flow
controller and second model will have artificial intelligence
based controlling technique. To design a controller for
enhancing the power output from the wind energy system
using UPFC. This will be made to feed DC transmission
system. Finally integrating the system with long distance DC
transmission system and then to the grid so as to make it
more reliable and efficient. In this work a coordinated
control based on Fuzzy logic for UPFC for cluster of offshore
WPP connected to the same HVDC connection is being
implemented and analyzed. The study is targeting
coordination of reactive power flow and active power flow
between HVDC Converter and the WPP cluster while
providing offshore AC grid voltage control. Thus it can be
drawn from this work that while designing a power control
strategy the proposed fuzzy logic based active power
controller in UPFC can serve the purpose with better results
in terms of active as well as reactive power. This control can
also be used in hybrid systems thus making it more reliable
controlling method. The
