has also been established in order to determine the system’s performance. Even so, for
clearness, the system’s behaviour and performance are given only for four days representing
the year’s seasons. Fig. 3 shows the fuzzy-command timing of relays during daylight.
During function, all appliances were switched on in order to evaluate the contribution of
the PVP generation to the whole installation. By examining the fuzzy decisions, it can be
deduced easily that frequent connections to grid and to the PVP output are observed for
appliances of lower power. This is due to the above management constraints (Section 2)
which affect the higher priority given to appliances of lower power in order to recuperate
the remaining power of the ones of higher power. As well, commutations can be seen with
appliances of high power when PVP generation is available (June and September). In this
case these commutations are limited to the time around midday. Finally, only lower-power
appliances are connected to the PVP output while the PVP generation is weak (December).
