Implementation of reference feedforward power synchronization control in a simulation environment

Abstract

This thesis presents the implementation and validation of the Reference-feedforward power synchronization control (RFPSC) method in a simulation environment. The RFPSC extends the classical power synchronization control (PSC) approach by introducing a feedforward term of the active-power reference, enabling enhanced damping and near pole-zero cancellation in the closed-loop response. A block-based simulation environment provides a graphical representation of the model and allows for component-wise tuning and testing. The implementation is evaluated under steady-state conditions, active-power steps under varying short-circuit ratios, and frequency deviations. The simulations demonstrate correct inherent synchronization, well-damped and effective active-power tracking and robust behaviour across varying grid strengths. The frequency deviation test further verifies the expected power-frequency coupling characteristics of PSC-based methods.
