ABSTRACT: The insertion of dispersed generation into existing electric power systems has a great impact on realtime operation and planning. Several uncertainties characterize the ability of the existing power system to integrate this form of generation, Hence, dispersed generation must be taken into consideration in power system performance so that operation and security are not disturbed. Dispersed generation increases the complexity of controlling, protecting and maintaining power distribution systems. This article focuses on some technical aspects, but not on the impact on the quality of supply and on tariff signalsIEEE Computer Applications in Power 05/1999;  1st 01/1994; Mc Graw Hill, Inc..

Conference Paper: Robustness analysis of periodic systems
[Show abstract] [Hide abstract]
ABSTRACT: Two approaches for robustness analysis of linear periodically timevarying systems are presented. In the first approach the state space matrices of the nominal system are expanded in Fourier series. The system can then be represented as an interconnection of a linear timeinvariant system and an uncertainty that contains all harmonic functions in the Fourier series. Integral quadratic constraints (IQCs) can then be used to derive robustness conditions, which are equivalent to several linear matrix inequalities. In the second approach, instead of being factorized out, the harmonic terms are kept in the nominal system. Periodic IQCs are then used to characterize the uncertainties. This generally gives a lower dimensional optimization problem but with added complexity due to the fact that the system matrices are periodicDecision and Control, 1999.
