The design and implementation of a new control scheme for reactive power compensation, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators in large interconnected power systems is presented. The nonlinear behavior of wind turbines has been represented in this paper by an uncertain term, derived from the Cauchy remainder of the Taylor...
This paper presents a nonlinear control design method for interconnected power systems with induction motors as dynamic loads. To design the controller, a feedback linearization technique is used. The control law is applied through the excitation system of the synchronous generator. The designed controller can provide a stable operation of the systems over a wide range of operating region. In this...
The complexity of power systems has increased in recent years due to the operation of existing transmission lines closer to their limits using flexible AC transmission system devices (FACTS), and also due to the increased penetration of new types of generators that have more intermittent characteristics and lower inertial response, such as wind generators. This changing nature of power systems has...
Power systems are composed of dynamic loads. In this paper, the induction motors which are widely used in consumption units are considered as dynamic loads. This paper presents an analysis to investigate the effects of large dynamic loads on interconnected power systems with power oscillation damping controller (PODC). The PODC is designed based on the conventional method of linearization. An overview...
