I. Introduction
An important need for the evolving and future need is deep decarbonization driven by the massive integration of renewable energy technologies. At the distribution level, the penetration of distributed energy resources (DERs) is increasing and it brings the need of analyzing the transient behavior accurately. A challenge associated with this transient analysis is the accurate modeling of inverter-based DERs. An electromagnetic transient (EMT) simulator, such as EMTP or PSCAD, provides high-fidelity modeling capturing the dynamics at a large range of frequencies. Unfortunately, this higher fidelity modeling comes at the cost of increased computational burden. As a result, EMT simulators suffer from scaling to wider areas and modeling large networks.
