Abstract: The evolutionary game theory is new development of the game theory. It initially arose from biology domain; along with the indepth study, the scientists introduced it into other fields gradually and have unearthed its important significance. There are mainly two methods to research the evolutionary game theory at present, one is analytic method, and another is computerbased simulation method. The Repast is one of the frequentlyused multiagentbased modeling and computer simulation platforms. Using the Repast simulation platform, packet the existed model (copied dynamical equation of state); carry out the simulation study under given conditions; use this method in electricity market to simulate the bidding behavior of the power generation enterprises. During simulation process, the dynamic processes of various power generation enterprises adopting different game strategies were well incarnated by the platform, and finally tended to their own equilibrium. The conclusion obtained by simulation is basically in accord with that obtained by analytic method.
