ABSTRACT: This paper proposes a novel method to calculate the best
installed capacity of pumped storage power station. First, we choose the day with maximum load as the
typical day for every month and simulate the system running in two cases of
whether the pumped storage power station is put into
operation. The difference of the total coal consumption
between the two cases is the peak load shifting benefit. Furthermore, we build load
model and power generation model to calculate the benefit of emergency use and frequency
modulation, which are the major projects of dynamic benefits. At last, on the
premise of ensuring the system requirements, the developed method employs
the maximum benefit of the
unit capacity as the objective function to get the best installed capacity of pumped
storage power station by simulations. Tests on a provincial power grid have
shown that the developed method which combines of load characteristics, electric
structure and other factors can get the best installed capacity of pumped storage
power station easily and has a certain guiding significance for the planning
and construction of the pumped storage power station.
