Abstract: Penetration of wind power generation into the power system has greatly affected the electrical power system because the increment of installed capacity of wind farms (WFs) causes the variable power flow in the system. This paper presents assessment of an electrical effects depending on the installed capacity of WFs. Firstly, a scenario is analysed power system before and after WFs connected into power system of the Central II-part of Lao PDR by DIgSILENT power factory software. Secondly, the installed capacity WFs is inserted into simulation with the two located. The propose of this study is comparative the result of electrical effects based on the ratio installed WFs each location. It has been demonstrated variable power flow and current flow into substations on the power transmission. In addition, the result shown limited performance of installed WFs power generation in the system. The outcome of a novel scenario is considering the power system to determine an electrical effect when the increment installed capacity of power generation also that is a planning extension of power generation in the Central II part, Lao PDR.
