A NEW MODEL AND ALGORITHM OF SECURE AND ECONOMIC AUTOMATIC-GENERATIONCONTROL

This paper presents a new nonlinear convex network flow programming (N LCNFP) model and algorithm for solving the on-line economic power disp atch 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 m odeling 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 a pproach is tested on an IEEE 30-bus system with satisfactory results. (C) 1998 Elsevier Science S.A. All rights reserved.
