Abstract

In terms of valve-point effect of the conventional generators

unit commitment is a complex combination of variables with mixed-type combinatorial optimization problems.Based on small-world network(SWN) model of the neighborhood structure and particle swarm optimization(PSO)

by taking with the minimum total consumption of all the units within 24 time periods as the objective function of

the mathematical model of optimal unit was established

which introduced the small world network model

featuring small average shortest path and clustering coefficient large

into PSO neighborhood structure.By taking the output power as the particle position

both SWN-PSO algorithm and genetic algorithm simulation were applied in a 10 unites system.The simulation results show that the proposed algorithm is conducive to information sharing between the particles

but also can converge faster and more accurately to the global optimal solution.
