Thesis Title: Coordinated Control of Virtual Inertia Units to Improve Frequency Stability of Islanded Microgrids

The rapid development of the use renewable energy sources (RESs) in power grids has led to the creation of small‑scale and local grids with the ability to operate in islanded mode called microgrids. Despite their numerous advantages, microgrids have high uncertainties in the production, consumption and structure of the network, which make it difficult to predict their dynamic behaviors. In addition, RES-based power plants, such as solar power plants and modern wind farms, are connected to the grid via electronic power inverters, and therefore do not have inertia due to the lack of rotating components in these structures. This will cause significant effects on microgrids, such as the reduction of frequency stability, significant frequency fluctuations, high rate of change of frequency, and disconnection commands for some equipment, etc. It can be concluded that the lack of inertia in the structure of these resources along with their different transient behavior in microgrids increases the negative effects on their performance and limit their applications. This Thesis aimed to present a novel control structure that guarantees the stable dynamic performance of islanded microgrids in the presence of distributed power generation resources based on power electronic inverters. Accordingly, an effort was made to propose a structure that includes distributed virtual inertia units interacting with a hierarchical control structure, while retaining the benefits of previous control methods. In addition, in order to enhance frequency stability in islanded microgrids, the virtual inertia parameters were optimally adjusted while taking into account the limitations imposed by the distributed units.
