Impact of Wind Generation on Dynamic Voltage Stability and Influence of the Point of Interconnection

In recent times there has been an increasing interest in wind power, particularly in areas like the New England region, which possesses abundant potential for developing wind generation. Dynamic voltage stability is one of the biggest concerns when conducting wind integration studies in a power grid. This paper presents an investigation of the voltage characteristics of an electric grid connected to wind generation and subject to fault conditions. A comparison of the dynamic voltage performance of synchronous machines and wind farms has been made while considering both type III and type IV wind turbines, as they are the dominant types in the market. In order to consider the typically remote location of wind farms, the present study also includes an analysis of the role that the point of interconnection of the wind farm plays in dynamic voltage performance. The IEEE 39-bus system is used as the case study to show our methodology.
