Mega penetration of photovoltaic power generation (PV) will be introduced in future electric power systems, dealing with environmental problems such as global warming and energy exhaustion. The authors have pointed out that diculties will arise in meeting the N‐1 security standard if increases in uncertainties cannot be avoided due to PV penetration. Thus, we have proposed a new concept of “robust power system security” together with several conditions to be satised in order to guarantee the N‐1 security standard under uncertainties. In this paper, (1) a model of uncertainties due to PV generation is proposed based on robust power system security; a method for proper parameter selection is also provided. Then, (2) the inuence on the stability of the PV and load disconnection from the power system is studied through simulation using the model system; (3) the eect of PV fault ride‐through (FRT) on stability is investigated along with dynamic voltage support (DVS). Finally, it is shown that (4) complicated and burdensome tasks will be considerably increased in power system operation planning and real‐time operation under future circumstances by the mega penetration of PV. © 2013 Wiley Periodicals, Inc.
