Model Selection and Data Assembly for Power System Simulations

Developing generic dynamic models for the 2030 Eastern Interconnection grid

“…However, ZIP load assumes a static (algebraic) correlation between load power and bus voltage, which apparently neglects the dynamics of component devices such as induction motors, discharge lighting, and saturated transformers. It is reported that detailed dynamic load modeling approaches render more accurate simulation results than the static modeling approaches [16]- [18]. Therefore, the 2030 EI dynamic model adopts both a ZIP load model and complex load model (CLOD [3]), which represents motors, discharging lighting, saturated transformers, and static load ( Figure 7).…”

Development of the Mathematics of Learning Curve Models for Evaluating Small Modular Reactor Economics

“…For the constant-voltage-behind-transient-reactance machine model (GENCLS), as amortisseur circuits are not modeled, partly approximates the damper winding effect during the first swing [12]. However, this practice fails to recognize the fact that the damping torque is frequency dependent rather than being proportional to frequency deviation [9]. In addition, the electrical damping effect would die out once the machine speed stabilizes, while in simulation the damping torque still exists as long as there is static frequency deviation.…”

Measurement-based Load Modeling Validation by Artificial Three-phase Short Circuit Tests in North East Power Grid

“…he important role of load model in analysis has been well recognized in power systems [1][2][3][4][5][6][7]. However, it is thought that loads are too complex that there are no ideal methods in load modeling.…”
