| Abstract |
High penetration of renewable energy resources affects several stability problems. There are lots of stability concepts, one of them which is strongly related to renewable energy resources is called the voltage stability. As shown in this paper, voltage instability in transient can be occurred by renewable energy generation increasing. It is necessary to analyze this phenomenon and how to solve the problems effectively. This paper shows how this phenomenon can be interpreted and analyzed according to load model such as constant power model and ZIP model, which is using a specific methodology called YV analysis. Also, by evaluating power flow in the power system, it shows the specific cause of the voltage instability in a specific location. Using the above results, it is suggested how voltage instability can be effectively improved and solved through simulation. |
