AMI-Based Energy Management for Islanded AC/DC Microgrids Utilizing Energy Conservation and Optimization

摘要

This paper presents a new approach for quasi real-time and adaptive energy management for islanded ac/dc microgrids using advanced metering infrastructure (AMI) data. This paper presents a sophisticated multi-objective algorithm by employing AMI-based energy conservation and optimization techniques, tailored for different operational scenarios. This paper argues that optimal operation can be achieved by defining new concepts, such as operation value factor that can inherently reduce system operational costs. Moreover, the results of this paper demonstrate how utilizing accurate load models can improve ac/dc microgrid efficiency. To test the performance and the applicability of the proposed solution, a modified 33-node islanded ac/dc microgrid is used as a case study in the presence of various types of ac/dc generating units and loads.
