Abstract
This chapter develops and presents a time resolution based hierarchy of microgrid models for analysis and control design purposes. The focus is on microgrids with distributed generation interfaced via grid-forming inverters. The process of developing the model hierarchy involves two key stages: the formulation of a microgrid high-order model using circuit and control laws, and the systematic reduction of this high-order model to reduced-order models using singular perturbation techniques. The time-scale based hierarchy of models is comprised of the aforementioned microgrid high-order model (μHOm), along with three reduced-order models (microgrid reduced-order model 1 (μROm1), microgrid reduced-order model 2 (μROm2) and microgrid reduced-order model 3 (μROm3)) which are presented in this chapter.
