| Abstract: |
| The simulation precision of the classic load model (CLM) is affected by the increasing proportion of installed energy
storage capacity in the grid. This paper studies the all-vanadium redox flow battery (VRB) and proposes an equivalent
model based on the measurement-based load modeling method, which can simulate the maximum output of the VRB
energy storage system and fit the external characteristic of the system precisely in the occurrence of large disturbance
and continuous small disturbance. The equivalent model is connected to CLM to form a generalized synthesis load
model (GSLM), which considers the parameters of distribution network and reactive power compensation. Compared
with CLM, GSLM has better structures and can describe the load characteristics of distribution network with energy
storage system more precisely. Simulation results validate the effectiveness and good parameter stability of GSLM, and
show that the higher the proportion of energy storage in the grid is the better description ability GSLM has. |
