Abstract

Abstract This paper presents a new nonlinear convex network flow programming (NLCNFP) model and algorithm for solving the on-line economic power dispatch and automatic generation control (AGC) with security and economy. Two AGC functions—load frequency control (LFC) and economic dispatch control (EDC) are modeled on the same timescale as EDC. This new AGC modeling and solution algorithm meets not only the control requirement of frequency and tie-line power as in the conventional load frequency control, but also the line security and system economy. The proposed approach is tested on an IEEE 30-bus system with satisfactory results.
