【Abstract】 For the purpose of the medium-term optimal scheduling, a two step model for load, thermal and hydro-plants are described. A nonlinear network flow algorithm with error control of the check-number based on the primal network flow method is presented. It is suitable for the condition of multi cascaded hydroplants and the rivers with branches. The approprlate computer program for monthly planning of the Northeast Electric Power System in China has been developed. The operational results show that the algorithm and model proposed are practical and efficient.更多还原
