Economic emission dispatch for wind–fossil-fuel-based power system using chemical reaction optimisation

摘要

This paper presents a chemical reaction optimisation algorithm based on the chemical molecular reaction tornoptimise total cost in wind–fossil-fuel-based power systems, while all operating constraints are satisfied.rnWith the continuing search for alternatives to conventional energy sources and global warming, it isrnnecessary to include wind energy conversion system generators in the economic load dispatch problem.rnThe random nature of wind power is modelled using Weibull probability distribution function. Becausernof uncertainty in wind power, wind cost is generalised by including overestimation and underestimation costrnof available wind power. The proposed approach is examined and tested on the standard Institute ofrnElectrical and Electronics Engineers 30-bus test system having three conventional thermal generators,rntwo gas generators, one oil generator and two wind turbines and a 40-unit test system having three windrnturbines and 37 thermal generating units. The simulation results show that the proposed algorithm givesrncomparatively better operational cost compared with other optimisation techniques. Copyright © 2014 JohnrnWiley & Sons, Ltd.
