In this paper, the proposed algorithm has been applied to a standard IEEE 30-bus test system with six generating units and three generating units. The results obtained with the proposed approach are compared

Dispatch

by Lahouaria Benasla, Abderrahim Belmadani, Mustapha Rahli, Lahouaria Benasla, Abderrahim Belmadani, Mustapha Rahli
"... This paper presents a new approach for solving the combined economic and emission dispatch problem under some equality and inequality constraints. The equality constraints reflect a real power balance, and the inequality constraints reflect the limits of real generation. The voltage levels and secur ..."

Relative and absolute strength of response as a function of frequency of reinforcement

by R. J. Herrnstein - J. Experimental Analysis Behavior , 1961
"... pigeons behave on a concurrent schedule under which they peck at either of two response-keys. The signifi-cant finding of this investigation was that the relative frequency of responding to each of the keys may be controlled within narrow limits by adjustments in an in-dependent variable. In brief, ..."

, the requirement for rein-forcement in this procedure is the emission of a mini-mum number of pecks to each of the keys. The pigeon receives food when it completes the requirement on both keys. The frequency of responding to each key was a close approximation to the minimum re-quirement. The present experiment

Unit Commitment, Economic Dispatch

by Young-beom Jung․kil-sin Kim․chang-ho Park․yong-beom Yoon
"... Though Korea has introduced CBP(Cost Based pool) power trading system since 2001, long-term Generation system planning has been executed by government for Cost minimization every 2 years. Until currently the model which is used for Generation system planning and best-mix only considers cost minimiza ..."

Economic Emission Load Dispatch using Interval Differential Evolution Algorithm

by Archana Gupta, Shashwati Ray
"... Abstract. Differential Evolution (DE) algorithm is a heuristic approach for minimizing nonlinear and non-differentiable continuous space functions (storn, 1997). However, the implementation of DE requires some estimate of the global minimum to be provided, which is difficult for any arbitrary functi ..."
