Abstract:

Inverter vendors usually have electro-magnetic transient (EMT) models of distributed energy resources (DERs) for validation purposes and these types of models are usually black-boxed considering intellectual property (IP) protection. Limited by small simulation time steps for the entire power system network, studying the system-level responses of DERs in EMT simulators is more time-consuming as the network size increases. Meanwhile, vendors usually do not have inverter models that can be used in three-phase phasor-domain simulators. This paper proposes a platform that can dynamically co-simulate the EMT inverter models and three-phase phasor-domain distribution networks considering the high penetration of inverter-based DERs. This platform is very useful for evaluating the impacts of vendor-provided black-box DER model on distribution system dynamics. The co-simulation platform is validated against the full EMT model using a simple two-inverter test system and tested using the IEEE 34-node test feeder.

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.
