The Model of the Optimal Expansion of A Hydro-thermal Power System

In this article, a model of the optimal expansion of a hydro-thermal power system for North-west electric power system(mainly for long-qin of Yellow River Hydro-stage power system)is presented, which is model (P) in the article. By the model, one can get the long-term optimal expansion plan of a hydro-thermal elec- tric power system, which is similar to the North-west's, and the reasonable pro- portion between hydro power and thermal power, and optimal choice of the hydro and thermal electric power resources. One can determine the order of construction of the generation plants, the scale of each plant, and the characteristic paramet- ers of the reservoirs, respectively corresponding to each hydro electric power station, and so on. The model is a non-linear mined integer programming. We suggest two kinds of methdos for solving the model-segment approaching method and Quadratic iterative method, and have developed a series of computer software -SWPLAN.
