Abstract
With increasing demand for generating electricity from clean energy, renewable energy sources (RESs), such as wind and solar, has gained much attention due to the clean and quiet characteristics. In many applications, connecting multiple RESs of different types (e.g., wind and solar), voltages, and capacities to a power grid or load is required. Single- phase inverters have been widely installed in residential power system to meet the full or partial load demand. In this work, multiport converters were developed for integrating multiple RESs, wind turbine and photovoltaic (PV) panel. Since the intermittent characteristic of the RESs, an energy storage device, e.g., batteries, needs to be used together. Frist, multiport DC-DC converters were proposed for simultaneous maximum power point tracking (MPPT) control of each source. However, the output of these converters is DC and cannot be directly connected to the AC utility grid which requires a DC-AC inverter regulates the voltage from DC to AC. This thesis introduces a single-phase, four-port inverter for integrating RESs to the AC utility grid. All controllers are developed in rotation d-q frame. The inverter not only can operate in a standalone mode, but also can works with other inverters with the droop control as well as the grid.
