Active power and frequency analysis of smart grid using simulink

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.
