An Analysis of the Wind Power Penetration Effect on Reduction the Harmonics Spread in Steady State Condition

In the development of Renewable Energy Source, there are very crucial challenges that must be faced. One of the challenges and characteristics of renewable energy sources is its intermittent nature, especially in Wind Power Plants. The intermittent nature can affect the power quality and frequency stability generated by wind power. The penetration wind power will certainly have an effect of the power flow electrical system. One of the problems that can occur in an electrical system is the spread of harmonics due to the use of non-linear loads on the system. This research consists of two scenarios, the first is simulation with injection of harmonic sources on buses serving industrial load without integrated with wind power and the second scenario is simulation of harmonic spread after penetration of wind power. Both scenarios are carried out with the assumption of steady state system conditions. This simulation is programmed using MATLAB R2017b. This research shows that the inclusion of wind power in the system causes a decrease in the value of THD v on some buses, but the total active power losses increase if the load value on the system remains constant.
