Abstract:
As the pumped storage capacity is a comprehensive decision-making problem,the entropy theory
is used to establish a comprehensive evaluation system. This method can prevent the unilateralism of
the single evaluation methods,and avoid the subjectivity of the other evaluation methods. It took into account
the indexes of alternative coefficient of thermal capacity,coal consumption and saving amount of
power system,peak-regulation proportion and loss of load probability to evaluate the various programs. A
matrix was built for analysis between the indexes and programs,and an improved entropy weight was used
to determine the weight vector, sorted by entropy theory to obtain the optimal solution. Through the analysis
of example grid dominated by thermal power,the optimal solution was obtained,and the extended peak
shaving method was used to dispatch a typical day load. Theoretical analysis and numerical results prove
that the entropy algorithm is feasible.
