Optimum Operation Scheduling of Electric Power System Including the Pumping-up Power Stations （Part 3） −Applying to A.E.P. 30 Bus Test System−

In the previous paper, we reported that, in the case of transmission loss involving, the order of efficiency of the pumping-up power stations is not equal to the one which makes optimum operation schedule. And this was certified from the results of the 6 bus test system calculations. In this paper, our method is applied to the A.E.P. 30 bus test system. We improve on the part of it which optimizes the operating patterns of pumping-up power stations and thermal power stations. From the model system calculation results, we report as follows. It is important to optimize the operating patterns of pumping-up power stations and thermal power stations. And the optimum operation decreases the operating fuel cost. Simultaneously, the load factor is improved. These effects are more remarkable at the lower load factor
