Load frequency control (LFC) in future power systems, in which a large amount of solar photovoltaic generation is introduced, is studied. The constraints on LFC resources are classified as rate, simple, and energy limits. First, the nonlinear transfer functions of the limiters are modeled using random noise input. Second, the transfer functions of limiters are characterized by the coefficients of necessary facilities (CoNF). Third, the appropriateness of the concept and the identified value of CoNF is demonstrated through numerical simulations using a simple power system model. A way to control the contribution of existing and introduced resources to regulation of frequency fluctuation is proposed and demonstrated.
