Abstract

Distributed energy resource (DER) has different power generation characteristics from conventional generators because wind turbine generators and photovoltaic generators are connected to grid through inverters. Therefore, transient stability analysis in power system with inverter-based DER should be conducted considering inverter characteristics because the inverter's operating modes can affect power system stability. This paper presents the definition of critical momentary cessation voltage for securing power system stability and estimates power system regional dependency of DER. The effectiveness and feasibility of the critical momentary cessation voltage are demonstrated in Korean power system. Transient stability assessment is used to verify the results.
