Reduced-Order Model of Power Converters to Optimize Power Hardware-In-the-Loop Technology in Dc-Distributed Systems

Proceedings of: 35th Annual IEEE Applied Power Electronics Conference and Exposition (APEC, 2020), 15-19 March 2020, New Orleans, LA, (USA). ; The Power Hardware-In-the-Loop (PHIL) technology provides a powerful tool for testing scenarios where there is a high-power interchange, in which the performance of field tests can be very complex or expensive. When performing PHIL simulations of systems with a high number of components, such as DC-distributed systems on a ship or aircraft, the use of switched or average models of the converters can require the use of expensive commercial real-time digital simulators (RTDS) reducing the advantages of these technology. This paper is focused on the proposal of a reduced order model of converters to be able to perform PHIL analysis of Dc-distributed systems using low resources of the required real-time digital simulator. The paper validates that the proposed reduced-order model is able to determine the stability on the Dc-distributed system in comparison with more complex converter models. Moreover, a comparison between both models regarding the required resources in the implementation in a commercial RTDS platform is performed to validate the benefits of the proposed model in performing PHIL analysis of large power distribution systems. ; This work has been partially supported by the European Regional Development Fund, the Ministry of Science, Innovation and Universities and the State Research Agency through the research project "Modelling and control strategies for the stabilization of the interconnection of power electronic converters" (FEDER/Ministerio de Ciencia, Innovación y Universidades - Agencia Estatal de Investigación/ _Proyecto CONEXPOT-2 (DPI2017-84572-C2--R)).
