C. Results and Analysis
1) Single day operation: Fig. 5 shows the simulated power flow of the PV system and SOC of the FESS for a single sunny day (September 5th, 2014). In the top graph the load PLB is shown, which is biased by the auxiliary power depending on the SOC of the FESS according to (6). Based on the priorities described in Fig. 1, the biased load is fulfilled in decreasing order by PV,discharging of the FESS and the grid. The PV generation (Fig. 5 middle) is used in decreasing order for direct
load supply,charging the FESS and grid feed-in.
