is sent by the E-box at the beginning of the night (t0 +Δt).Between 7h00 and 9h00, the PV power is not enough (seeFig. 5); the power reference is well calculated for the gasmicroturbine (see Fig. 9).
After 9h00, the turbine power reference is set to the minimumvalue until 7h00. At 19h30, the power reference for theprosumer is adapted to discharge the batteries; the peak valueof the turbine power reference is reduced (see Fig. 9). Fig. 10shows the sensed value of the PV power and the theoreticalone, which can be generated with an MPPT algorithm. Between11h00 and 12h30, the available PV power exceeds the requestedpower from the loads. Fig. 10 shows that all the PV power is notdelivered to the grid. The local EMS has stored or limited partof the available PV power; the implementation is detailed in the
next section.
Fig. 11 shows that the real sensed value of the total loadpower may besignificantly different from the 24-h-ahead estimatedone. The task of the primary control is to eliminate theseerrors. This primary control is included inside each local energymanagement of generators.
