Compensation Using D-Statcom with a Dissipativity-Based Controller Authors: Gerardo Escobar, Aleksandar M. Stanković, Paolo Mattavelli, Volume: 1, Page 3051 Paper number 2141 Abstract: In this paper we present a solution to the problem of reactive power compensation and harmonic compensation in the general case when both the source voltages and the load currents are unbalanced and contain an arbitrary number of harmonics. For the compensation purpose, a D-Statcom is connected in parallel to inject the required currents, so that from the source terminals the same apparent resistance is observed in all phases and at all frequencies. A controller based on the ideas of passivity theory, to which we have added adaptation to compensate for the unavoidable uncertainty in some of the parameters, is suggested as a solution. One of the major advantages of this solution compared to conventional ones is that we are able to perform precise tracking (also for high order harmonics) even in the presence of a relatively low switching frequency, i.e., in presence of an active filter with limited bandwidth. Simulation results are provided to illustrate the performance of our controller. CD002141.PDF (From Author) TOP Control of the System Synchronous Generator-Exciter via VSC Authors: Alexander G. Loukianov, Javier Cabrera-Vázquez, José Manuel Cañedo, Vadim I. Utkin, Juan Manuel Ramírez, Volume: 1, Page 3057 Paper number 1640 Abstract: The objective of this paper is to design nonlinear observer-based excitation controller for power system comprising a single synchronous generator connected to an infinite bus and an exciter system. The controller proposed is based on the using Variable Structure Systems and singular perturbation systems concepts, and Block Control Principle. A nonlinear observer for estimation of mechanical torque and rotor fluxes, is included. This combined approach enables to compensate the inherent nonlinearities of the generator and to reject external disturbances. CD001640.PDF (From Author) TOP Design Of Passivity-Based Output Feedback Controllers For Power System Stabilization Authors: Catherine M. Falkner, Bonnie S. Heck, Volume: 1, Page 3063 Paper number 83 Abstract: This paper develops a method for designing passivity-based output feedback controllers for complex nonlinear systems that are not inherently passive. Using this methodology, three power system stabilizers are designed; two of these are output feedback sliding mode controllers and the third is designed using basic passivity principles. The controllers are examined to see how well they handle model uncertainty, disturbances and measurement noise. The results are compared to a previous study performed on the same benchmark power system model using six standard controllers. It was found that two of the new controllers designed in this paper outperformed the best of the controllers in the previous study. CD000083.PDF (From Author) TOP Neural-Net Based Control Structure With FACTS Devices Authors: Dingguo Chen, Ronald R. Mohler, Volume: 1, Page 3069 Paper number 1355 Abstract: Load side voltage stability is a main concern in this paper. Neural-network based dynamic load model is incorporated into voltage stability analysis. FACTS (flexible ac transmission systems) devices, such as TCSC (Thyristor Controlled Series Capacitor) and SVC (Static Var Compensator), are applied for power system stability enhancement. The use of dynamic load model and FACTS devices for control may sometimes lead to excitation of generator dynamics, resulting in the whole power system more complex. Conventional methods often neglect either the load dynamics or generator dynamics while the proposed methods deal with both. For the convenience of control design, proper system models are developed. Methods are presented for TCSC and SVC control cases to represent the controlled system through three sets of equations: generator dynamics, load dynamics and control constraints. The control is then synthesized in the form of neural networks, trained by using the pre-specified optimal trajectories. Under some circumstances, simplified neural controllers can be synthesized. CD001355.PDF (From Author) TOP Study of Hopf Bifurcations in a Simple Power System Model Authors: Juan Li, V. Venkatasubramanian, Volume: 1, Page 3075 Paper number 1996 Abstract: This paper studies the occurrence of Hopf bifurcations in a simple single-machine-infinite-bus (SMIB) power system model. Our interest is primarily on the subcritical or supercritical nature of the Hopf bifurcations under variations in operating parameters. We observe that the Hopf bifurcations are mostly subcritical. When the exciter control is a fast high gain control and when the Thevenin equivalent transmission line impedance is high, the Hopf bifurcation can become supercritical leading to birth of stable limit cycles. Two degenerate bifurcations namely, one related to double zero eigenvalues, and the other related to Hopf normal form coefficient becoming zero, give rise to homoclinic orbits and nested limit cycles respectively. CD001996.PDF (From Author) TOP Global Control of Stressed Power Systems Authors: Seyed A. Shahrestani, David J. Hill, Volume: 1, Page 3080 Paper number 1163 Abstract: A multilevel control scheme that is capable of system control over wide ranges of operating conditions for nonlinear systems is proposed. The first control level confines the system operation to some reference segments in its state space. Each reference segment is further subdivided using bifurcation analysis for establishing the bounds on regions of the state space of the system with different control requirements. The principles of global control lead to a hierarchical control structure which combines regional (linear or nonlinear) controllers smoothly. The scheme is illustrated for control of a power system known to have complex dynamical behavior for a wide range of loading levels. CD001163.PDF (From Author) TOP A Non-Linear Wind Velocity Observer For A Small Wind Energy System Authors: Daniel Sbarbaro, Ruben Peña, Volume: 1, Page 3086 Paper number 1045 Abstract: In this paper a non-linear strategy is presented to estimate the wind velocity in a variable speed small wind energy system. The approach is based on a non-linear state observer considering the rotational speed and electrical variables as the measured ones. The observer is based on a general non-linear model of the wind turbine characteristic and an assumed wind variation model. This approach is simple and does not require a complex searching algorithm to find the estimates. In addition, the convergence of the estimates can also be analyzed using standard tools. Results of wind velocity estimation using realistic wind profile, representing some wind conditions in the World most southern city of Punta Arenas, show the performance of the proposed approach.
