Abstract

Grid-connected operation of Renewable Energy and Storage (RES) nodes make
the dynamics of modern power grid to be more complex. A model of power grid,
considering RES nodes, is being proposed to address frequency synchronization
and stability analysis. First, a unified dynamical model of four different types of
nodes are established according to the swing equation, including the RES nodes
with power-frequency droop inverter controllers. The storage nodes have charging and discharging states. We provide a sufficient condition for the existence and
stability of frequency synchronized solution via the linear time-varying consensus protocol of multi-agent system. The results are validated by Western System
Coordinating Council and the Shaanxi North Power Grid model.
