Abstract :
Solid State Transformer (SST) average models are needed to enable system and protection studies. This paper focuses on fine tuning existing average models to replicate their switching counterparts and also discusses and validates control modifications required for successful grid integration. A 3 phase test system comprised of Substation SSTs and load SSTs of different ratings has been developed in PSCAD. The SST´s response under fault conditions and its ability to integrate distributed resources in a seamless manner are shown. In addition other features such as the SST´s internal over-current and over-voltage protection and its ride through capabilities are discussed..
