energy resources do not change significantly over one single hour.
In order to evaluate the performance of employed components in
solution 3, the daily simulation results through a year can be
observed in Figs. 15e18. Fig. 15 shows the daily distribution of
produced electricity by the wind turbine per kWh. From this graph,
it is clear that there is appropriate potential of wind energy in the
location which results in capacity factor of 31.5% for the wind turbine.
It should be noted that in Figs. 15e18 day 1 refers to the first
day of the year which is the January first.
As seen from Fig. 15, required electricity is first met by available
wind energy at each time step. In case of electricity shortfall, the
leftover electricity load is met by electricity that bought from the
grid, Fig. 16. Whenever renewable energy generated in electrical
form is more than the electrical needs, the excess renewable energy
is sold to the grid with price mentioned in Table 7. Fig. 17 indicates
the daily sold electricity to the grid, which is generated by the
hybrid renewable energy system over one year.
Fig. 18 represents daily biomass boiler production. The biomass
boiler described in the configuration proposed by the solution 3 is
utilized for heating and hot water purpose. The results justify using
the biomass boiler during the year.
As it is seen, the boiler output is approximately constant during
the summer since the daily hot water load is assumed constant
