A Fully Distributed Architecture for the Hybrid Cascaded Converter based Utility Interface

This paper attempts to develop a utility interface for hybrid renewable energy resources, which is based on the hybrid cascaded converter so that several solar panels and one wind turbine can be integrated together. Different from conventional centralized architecture, this paper decentralizes not only the controller but also the modulator to enhance the modularity and the scalability of the overall system, becoming a fully distributed architecture. Further investigation shows that the power variation between the solar panels and the wind turbine has almost no influence on the power quality. Laboratory test results are provided to verify the feasibility of the discussed system.
