Power System Stability Research in the Integration of Wind Power Plant in Almaty Region

Today, the cost of renewable energy has equaled the price of traditional energy sources, and in most countries ”green” electric energy has become cheaper than electricity on carbohydrate fuel. Therefore we are less and less beginning to discuss the mechanisms of economic support for renewable energy, but the problem of balancing is still on the agenda. This paper examines the influence of Wind Power Plant during its integration to the electrical grid of 110 kV and higher. The aim of this work is to study the integration of WPPs into traditional power system taking into account the standards and requirements. The object of the study is a WPP in the Almaty region with a capacity of 60 MW. Rotor-angle stability, voltage stability, quasi-dynamic analysis, of the electrical system during the integration of the WPP was carried out. Special attention was paid to the small signal stability, considering the influence of the power system stabilizer and the WPP on the power system.
