This paper presents a telecom power plant that uses local distributed generation resources and the utility grid as power inputs to the system. The microsources are connected to a high voltage main dc bus using multiple-input dc-dc converters. Additional converters are used in the secondary power distribution frames. The proposed architecture reduces the energy storage requirements and is more reliable than a traditional power plant. The system configuration is highly flexible and cost effective. This paper also introduces a topology for the multiple-input dc-dc converters and explains some control approaches. The analysis is supported by simulation and experimental results.
