Modeling Load Stochastic Jumps for Power Systems Dynamic Analysis

This letter proposes an approach to model power system loads as stochastic processes that incorporate both continuous and event-driven dynamics. The letter provides a brief theoretical background on the stochastic differential equations defining Ornstein-Uhlenbeck processes with jumps used for the stochastic modeling of power system voltage-dependent loads. The all-island 1479-bus Irish transmission system serves to illustrate and test the proposed jump-diffusion model.
