This book was released on 2021-08-31 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of power systems and microgrids is compromised by the increasing penetration with power electronic devices, such as wind turbines, photovoltaics and batteries. A simulation and optimization environment for such low-inertia systems is created. It is investigated how accurate the models need to be to capture the prevailing modes. An evolutionary algorithm tailored to optimization problems with computationally intensive fitness evaluation is proposed in order to optimized the controller parameters of grid-forming and grid-supporting distributed generators. It becomes apparent that microgrids dominated by grid-forming inverters are very stable systems when well-designed and optimized controllers are used. Model simplifications, such as the neglect of inner control loops of inverters, must be examined carefully, as they can lead to an inaccurate stability assessment.

Download or read book Stability Analysis of Power Converter Dominated Microgrid written by and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power systems are going through a paradigm shift from electric machine-based to power electronics-based, with a huge number of different players on the supply side. Nowadays, thousands of distributed energy resources (DERs) are being integrated into power systems through power electronics components such as solar panels, wind turbines, and energy storage systems; however, the integration of numerous power electronic components and constant power loads (CPLs) destabilizes power systems and leads to critical oscillations. Consequently, one of the crucial challenges of this new paradigm is to keep the whole power system stable. The stability issues faced by DC microgrids are especially severe and urgent due to their unique properties. First, the low inertia of DC microgrids sharply weakens their stability; and second, owing to their advantage of smooth control, DC microgrids are unprecedentedly more promising than AC power systems given the increasing penetration of DERs. Therefore, the main purpose of this research is to solve the stability issues in power-converter-dominated DC microgrids. Considering the limited applicable ranges of traditional small-signal stability analysis, this research develops stability analysis of power-converter-dominated DC microgrids from the perspective of large-signal stability analysis. The main contributions of this research can be summarized as follows: 1) We model the DC microgrids with high penetration of power electronic devices and CPLs based on Brayton-Moser's potential theory, including a proposed novel current-mode controller of power converters and a more realistic model of CPL. 2) We present a rigorous derivation of sufficient criteria for large-signal stability in DC microgrids with multiple power converters and CPLs. It is worth mentioning that this derivation works for many different types of power converters. In this research, the stability of each equilibrium point and the convergence of state trajectories with different starting points are discussed in detail. We integrate the discussion of the local stability of each equilibrium point into the large-signal stability analysis of the system. 3) We develop a novel approach to ROA estimation with less conservativeness using a potential-based approach. The approach tackles the common conflict between model accuracy of ROA estimation and computational overhead. 4) We resolve misunderstandings and emphasize the key points of potential theory, which plays a fundamental role in large-signal stability analysis in nonlinear power grids. Additionally, this dissertation develops a preliminary study about the microgrid control and voltage stability in AC/DC hybrid microgrids in Chapter 5, which investigates the control techniques, simulation modeling, and voltage stability analysis when a DC microgrid is connected to an AC microgrid. We will extend the preliminary study from the perspectives of stability-aware power flow management, fault detection, and grid protection in our future work.
