Impact of fault ride-through characteristics of high-penetration photovoltaic generation on transient stability

In recent years, many utilities throughout the world have been moving toward the utilization of renewable energy, e.g. wind power or photovoltaic (PV) which is an alternative, clean and sustainable energy source for the electricity production. This paper focuses on the grid-connected PV systems and their impact on the system transient stability. The modeling of the PV systems developed within the MATLAB Simulink environment is presented. The impact of fault ride through characteristics of a large penetration of PV generation on the system transient stability is examined through numerical simulations conducted on the IEEJ West 10-machine test system. Several of interesting aspects are presented and discussed.
