Parallel Operation of Grid-Forming Inverter Systems Considering DC-Side Dynamics
Renewable energy resources such as wind and solar power are often tied to the grid using dc-ac power-electronic converters. Unlike large power plants, these sources of energy have a dispersed nature, i.e., they are comprised on many small units that are operated in parallel to form a large power plant. This project deals with investigating the dynamics of these highly sophisticated, paralleled sources, their modeling, and control interactions. In particular, the project will consider the implications of paralleling and the impact these sources have on the dc side of the converters. Mathematical modeling, detailed computer simulations, and real-time hardware-in-loop setups will be used to approach and solve these issues.
