Abstract
Intelligent, networked microgrids are becoming increasingly desired for land, sea, and space applications. These self-contained power systems contain limited power availability, but feature two-way communication infrastructure allowing for detailed power measurements and discrete control. Thus, control of individual loads is essential to maintain acceptable system operating conditions. Furthermore, the ability to remotely control these power systems is invaluable when locally enacted control is infeasible. Therefore, developing a system that represents an intelligent microgrid with remote controllability can represent these capabilities, and can be used as tool to test and evaluate ways to address measurement, control, and communication challenges. In order to study the behavior of these systems, a reconfigurable laboratory-based hardware and software microgrid power system was developed, presented, and tested. This system allows for measurement collection and centralized control of remote devices, through an Energy Management System. In the Energy Management System software, collected data is processed using state estimation, which allows for mathematical determination of unknown parameters using a select set of known data. Multiple cases were studied with varying sets of measurement data provided to the estimator. Additionally, two system control cases, composed of remedial voltage control actions, and control actions to meet power demands of critical loads, are presented. During each control action case, the system response is analyzed. Overall, both the measurement and control cases presented successfully demonstrate the system and software capabilities.
