Load frequency control (LFC) in future power systems, in which a large amount of solar photovoltaic generation is introduced, is studied. The constraints in 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 coefficients of necessary facilities (CoNF). Third the appropriateness of concept and identified value of CoNF is demonstrated through numerical simulations using a simple power system model. Also a way to control the contribution of existing and introducing resources to regulation of frequency fluctuation is proposed and demonstrated.
