Abstract

Power quality is important for distribution system as it may impact both the provider and consumer of the electricity negatively if it has an issue such as harmonic current. This issue may result in a breakdown of equipment of both the consumer and the provider hence why it important to solve the power quality issue. Therefore, this research is conducted to overcome the power quality issues that is faced by the distribution system by adding DSTATCOM to the system as it can compensate harmonic current. Fast Fourier Transform (FFT) is chosen as DSTATCOM controller for this research. The outcome for this project is that the THD value of the source current need to be below 8% as stated in IEEE standard 519-2014. All the simulations are performed by using MATLAB/Simulink where it has been proved that the THD of source current has been greatly reduced after adding DSTATCOM compensation to it.
