| Summary: | Reactive power compensation and harmonics control are becoming important tasks to sustain the quality of power supply in microgrids. A distribution static synchronous compensator (D-STATCOM) is a device which is generally used to provide compensation of the reactive power, and it also has the function of controlling harmonics in microgrids.
However, the traditional hysteresis method used to control the D-STATCOM has some shortcomings. Using the model predictive control (MPC) based D-STATCOM can get better reactive power compensation effects and reduce the harmonics.
In this project, the mathematical model of the integrated system was formulated and built up on the Simulink platform. Then the instantaneous reactive power (IRP) theory was used to calculate the reference current. After that, the principle of the hysteresis based D-STATCOM and MPC based D-STATCOM were discussed and built in the Simulink platform. Finally the discrete time simulation and real-time simulation were carried out on the Simulink platform and OPAL-RT. Their performances were also compared and discussed. |
