TOU tariffs assign each hour of each day to one of several periods. The current implementation of TAP allows three periods: peak, off-peak and shoulder. Different tariffs apply in each period.
A TOU mask is a set of three time series P(j), F(j) and S(j), j=1,8760.
By definition:
· P(j) = 1 if hour j occurs during a peak period, P(j) = 0 otherwise.
· F(j) = 1 if hour j occurs during an off-peak period, F(j) = 0 otherwise.
· S(j) = 1 if hour j occurs during a shoulder period, S(j) = 0 otherwise.
· P(j) + F(j) + S(j) = 1 for all j.
