STANDARD LOAD MODELS FOR POWER-FLOW AND DYNAMIC PERFORMANCE SIMULATION

We recommend standard load models for power flow and dynamic simulatio n programs. The goal of this paper is to promote better load modeling and advanced load modeling, and to facilitate data exchange among user s of various production-grade simulation programs. Flexibility of mode ling is an important consideration. For transient stability, longer-te rm dynamics, and small-disturbance stability programs, we recommend th e structure of multiple load types connected to a load bus. Load types are static including discharge lighting, induction motors, synchronou s motors, and transformer saturation. For each load type, multiple mod els may be connected to the bus. For longer-term dynamics programs, a model for LTC transformers is also recommended.
