This paper study the problem of our country’s electrical energy flow optimization. Two optimization model, whose objective functions are minimization transmission costs and maximum electricity price competitiveness respectively. The the parameters needed for the problem and optimization algorithms are also introduced in the paper. Furthermore, by using our country actual data , the paper give the optimization results of two model. Finally, based on the results of two optimization model, one resonable electrical energy flow suggestion of our country in the future is given in the paper.
