Environmental and economic dispatch of Microgrid using chaotic ant swarm algorithms

With the decreasing of the fossil energy source and the increasing of load demand,making full use of clean and renewable energy,distributed generation technologies gain more and more attentions.According to the characteristics of distributed generation in Microgrid,such as photovoltaic(PV) and wind turbine(WT),considering different fuel,efficiency,operation and maintenance costs,greenhouse gas emission level of distributed generation with various types and capacity,characteristic of PV and WT,a novel model environmental and economic dispatch of Microgrid was presented,which considered generation cost and emission cost.According to the different weights of generation cost and emission cost,the simulation results shows the correctness and validity of the model and chaotic ant swarm algorithms.
