Abstract: Aiming at the characteristics of bidding institution and cascade hydropower stations, this paper proposed that the cascade hydropower stations were taken as a united generation company in electricity market for optimal dispatching and profits. Multiple constraints were considered to build a reasonable dispatching model for cascade hydropower stations in electricity market. The criterion of Metropolis was quoted into the ant colony algorithm for correcting the problem of stagnating in ant colony algorithm and the algorithm was used for dispatching model. Via the example simulation of Songjianghe cascade hydropower stations, accuracy of the improved ant colony algorithm was verified and the advantages and disadvantages of the constructed models were pointed out.
Key words: cascade hydropower stations; optimal dispatching; improved ant colony algorithm; Metropolis criterion
