This paper presents an outline of an operation simulation program, developed at Tokyo Electric Power Company (TEPCO), of power plants in large power systems, mainly utilized for generation mix planning. The simulation algorithm of the operational performance of pumped-storage hydro plants is focused on in this program.
One of the main goals in a generation mix planning problem is to minimize the total of investment and operation costs. Applying a mathematically optimizing method to solving a generation mix problem involving the complicated operation of pumped-storage hydro plants has so far proven difficult, and has been in little use at TEPCO for actual power source development planning. The developed program simulates practical operation of the pumped-storage plants in order accurately to evaluate the annual operation cost. In this simulation program, each pumped-storage plant is operated taking into consideration of the condition of its reservoirs as well as their weekly operation cycles.
An application result of this program to a study of the quantitative optimization of pumped-storage hydro in a model system with nuclear plants and thermal plants of various fuel-fired types is presented.
