Abstract:
In this project, a Smart Grid has been designed by MATLAB/SIMULINK approach
for synchronization of Thermal and Wind power plant and for analysis of Active-Reactive
power and grid frequency. Analysis of Active power and frequency gives the exact idea to
know the range of maximum permissible loads that can be connected to their relevant bus bars.
Reactive power flow between a wind turbine system and the grid is an important issue
especially when the wind turbine is connected to a grid because
Wind turbine power production depends on wind speed. The output power is not
constant at all as wind speed changes all times. Output Voltage and frequency of these power
plants must be same to avoid circulating current in existing power system network in the
synchronization process. The maximum and minimum frequency deviation calculated for this
smart power system network explains about the permissible range of active and inductive load
applied at different load bus, from which stable working condition of the system has been
deduced in order to satisfy the frequency deviation of + 3%.
The Smart Grid, regarded as the next generation power grid, uses two-way flow of
electricity and information to create a widely distributed automated energy delivery network.
