  • Exhaustive Modal Analysis of Large-Scale Interconnected Power Systems with High Power Electronics Penetration
    IEEE Transactions on Power Systems, 2020
    Co-Authors: Mohamed Kouki, Bogdan Marinescu, Florent Xavier
    Abstract:

    Eigencalculation is a challenging task in large-scale Power systems with High Power Electronics penetration for at least two reasons. First, the well-known inter-area modes are no longer the only coupling modes as such couplings may involve also Power converters. Next, it is difficult to find all coupling modes without a priori knowledge about the system. In this paper we propose a new method to overcome these difficulties. It is fully analytic, i.e., does not need operator manipulations like dynamic simulations, and exhaustive in the sense that makes a full scan of the system for coupling modes. As a consequence, the real modes can also be fully identified. The approach involves concepts from matrix computation and dynamic systems analysis which hold in large-scale and need no hypothesis (like the one about large inertia generators usually associated to inter-area modes) or knowledge about the structure of the Power system. Validations on several models are presented, including realistic large-scale model (more than 1000 generators/dynamic devices) of the European Power system.

  • Use of the opposition Method in the Test of High Power Electronics Converters
    IEEE Transactions on Industrial Electronics, 2006
    Co-Authors: F. Forest, J.-j. Huselstein, S. Faucher, M. Elghazouani, P. Ladoux, T. Meynard, C. Turpin, F. Richardeau
    Abstract:

    The test and the characterization of medium or High-Power electronic converters, under nominal operating conditions, are made difficult by the requirement of High-Power electrical source and load. In addition, the energy lost during the test may be very significant. The opposition method, which consists of an association of two identical converters supplied by the same source, one operating as a generator, the other as a receptor, can be a better way to do these test. Another advantage is the possibility to realize accurate measurements of the different losses in the converters under test. In the first part of this paper, the characteristics of the method concerning loss measurements are compared to those of the electrical or calorimetric methods, then it is shown how it can be applied to different types of Power electronic converters, choppers, switched mode Power supplies, and pulsewidth modulation inverters. In the second part, different examples of studies conducted by the authors, and using this method, are presented. They have varying goals, from the test of soft-switching inverters to the characterization of integrated gate-commutated thyristor (IGCT) devices mounted into 2-MW choppers.
