3.1.1 Electric load

In order to optimally design a HRES, electric load information such as peak load, daily average electricity consumption and hourly load profile are of critical importance. The maximum availability of load information enables designing a more compact HRES. In the present case, the load data were not collected from any official government source (because of unavailability of such data), but from a previous study on Deokjeokdo island [11]. The average daily load was found to be approximately 24,720 kWh with peak load of 2292 kW typically occurring during winter season and total annual electricity consumption corresponds to a value of 7.296 GWh. The electricity consumption during winter season is higher than rest of the seasons due to the extensive use of space heating equipment powered by electricity. Figure 14 shows the daily and monthly electricity consumption at Deokjeokdo island.
