Stability Assessment Extensions for Single-Phase Distribution Solid-State Transformers

Abstract

In this letter, a stability assessment for single-phase solid-state transformers (SSTs) is extended to include the impact of distribution system voltages and a system-wide impedance analysis. It is shown that if the SST filters throughout the system are designed with regards to the proposed stability criterion, then system stability is guaranteed regardless of configuration. This leads to two resulting applications: 1) the order in which the SSTs are connected to the system will not generate instability if the criterion is satisfied and 2) a system configuration change due to a fault will not produce instability.
