Data-Driven Power Flow Linearization: A Regression Approach

Understand

The linearization of a power flow (PF) model is an important approach for simplifying and accelerating the calculation of a power system's control, operation, and optimization.

• Traditional model-based methods derive linearized PF models by making approximations in the analytical PF model according to the physical characteristics of the power system.
• Today, more measurements of the power system are available and thus facilitate data-driven approaches beyond model-driven approaches.
• This work studies a linearized PF model through a data-driven approach.
