Abstract

This paper will present the design of collective feedback controllers for the integration of renewable energy into networked DC bus microgrids. These feedback controllers are based on a single DC bus microgrid because the networked DC bus microgrids are self-similar. As a result, these feedback controllers are divided into two types. Type 1 is based on a feedback guidance command to determine the boost converter duty cycle. Type 2 is based on Hamiltonian Surface Shaping and Power Flow Control (HSSPFC) [1], [2], [3], [4], [5], [6] to determine the required distributed energy storage systems to ensure stability and performance. Two DC bus microgrids coupled with a transmission line is used as an example. This model architecture can vary from 0% energy storage with transient renewable energy supplies to 100% energy storage with fossil fuel energy supplies which will be useful in the future to demonstrate the benefits and costs of networked microgrids. © 2012 IEEE.
