This paper presents a mathematical model for peaking units optimal expansion planning by weekly regulaion pumped storage power station, in which the production simulation based on weekly load is introduced. Mathematically, the peaking units expansion planning problem takes into consideration with a set of equality and inequality constraints. The objective function of the proposed model is the least total accounting fee, including investment fee, operating fee and power cut loss fee as payout and other benefit as income. The constraints of the model contains the reserve capability constraints, the maximum installation capability of the generator, the maximum and minimum output of the generator constraints, the fuel consumption of the thermal station constraints, the water consumption of the hydro-station constraints, the reservoir capability and the spare capability of the pumped storage station constraints. By analyzing and comparing technical indexes and economical indexes obtained by production simulation the most desirable and economical planning scheme of peaking units can be found from all possible schemes. The optimal scheme can point out whether to build or not to build the pumped storage power station, its arrangement and dispatch model, etc. The proposed model is implemented on a practical planning program of a practical power system with pumped storage power station in the middle China. The results of optimization calculation show that pumped storage power station with weekly regulation characteristic has the same ability as that with daily regulation characteristic in substituting thermal station. However, weekly regulated station has more benefit in the whole economy and saving coal, but not so good as daily regulation in peaking.
