In order to study the influence on the generation cost caused by the load frequency regu-lation in power system,an OPF model combining the load effect of frequency and voltage regula-tion has been established in this paper.In the model,the load effect of frequency and voltage reg-ulation would be considered in the equality constraint,and the voltage magnitudes and the system frequency would be considered in the inequality constraint.The optimization model was solved by using the nonlinear primal-dual interior point algorithm,which is with high robustness and con-vergence.Simulation analysis results show that the load frequency regulation has important influ-ence on the generation cost.
