AN EFFICIENT METHOD FOR PUMPED-STORAGE PLANNING AND EVALUATION

An efficient method for systematic planning and evaluation of pumped-s torage plants is developed, in which a detailed operation simulation u sing an hourly chronological probabilistic production costing model is introduced so that the time dependency of storage operation policies through the charging and discharging processes is reflected. The optim um capacity of pumped-storage plants is chosen to minimize the overall system cost. In addition, peaking constraints are incorporated both i n the thermal unit planning model and in the daily operation simulatio n model. So it is well-suited to the planning and evaluation of peakin g plants. In this paper, a detailed description of the algorithm is pr ovided and a real application to the East China Electric Power System is discussed. (C) 1997 Elsevier Science S.A.
