It is well accepted among the power system community that the load model has an important impact on the stability studies of power systems. In this paper, we study the sensitivity of the small disturbance angular stability of power systems to the behaviour of load response. A transfer function representation of loads is developed from the linearization of the composite load models and dynamics of...
This paper studies the impact of displacing conventional synchronous generators with wind turbine generators (WTGs) on the damping of inter-area modes. The impact of tie-line power, which can be beneficial or detrimental with increased wind penetration on the damping of the inter-area mode in a two-area test system, is investigated. It is seen that the inter-area modes are more prone to instability...
In this paper, the impact of increased penetration of wind generation on the damping of the inter-area modes in two different topologies of a three area test system is studied. Four different scenarios based on different power trading schemes between areas are defined and the role of tie-line power in the evolution of the inter-area modes is evaluated. The results magnify the importance of the tie-line...
Power systems are shifting toward utilizing higher penetration of renewable energy sources (RESs) and especially wind generation because of the need to reduce carbon emissions over the next several decades. Small signal stability can be influenced with increasing penetration of wind generation in power systems. Poor damping of low frequency electromechanical oscillations are a threat to secure operation...
