Analysis of the stability of power electronics systems: A practical approach

Current trends in power distribution systems, such as telecommunications, computers, transportation and utility grid applications, are focused on distributed architectures instead of centralized approach. Distributed architectures are more complex since a network of power electronics converters is required to distribute power with appropriate performance. Hence, new challenges regarding integration of a power distribution systems made up by multiple converters must be addressed since the active nature of power electronic converters results in complex dynamic behavior when they are interconnected to each other. In addition, these power distribution systems are typically comprised of subsystems made up by a variety of manufacturers, which do not provide the data required to parameterize a model due to reasons of confidentiality. In this paper, a practical approach to analyze the stability of power distribution systems is proposed in order to provide an easy method to develop the integration of power distribution systems.
