Abstract

As the electrical grid moves towards modernization and the prevalence of DC architectures, microgrids, and distributed generation increases, the interactions and performances of these DC topologies must be understood and evaluated. Focusing on microgrids, these independent electrical entities typically have distributed generation, local load, some form of energy storage, and a connection with the electrical grid. When instabilities arise on either the grid or the microgrid, the connection can be severed, allowing the microgrid to operate self-sufficiently. While the microgrid is in isolation, resource management is of primary importance as the grid is no longer electrically connected to make up deficits in power that might arise.
This research focuses on utilizing a power management algorithm to maximize the efficiency of an isolated microgrid, as to minimize the losses of the system while limited resources are available. The microgrid consists of photovoltaic generation, local load, a series resonant load converter, and energy storage. The energy storage is placed in parallel with the load converter and is interfaced via bi-directional converters to the front and back ends of the load converter. Utilizing the energy storage as a functional load or source, the operational point of the load converter can be adjusted and consequently the efficiency of the converter can be optimized. In the work that follows, the design, control, and operation of the aforementioned system are detailed, as well as the autonomous power management logic, which governs the allocation of microgrid resources for optimization of the load converter and thus the microgrid system.
