Impact of wind and photovoltaic power plants installation share on the country power system load: case of Croatia

While the new 2030 European framework for climate and energy policies requires a reduction in greenhouse gas emissions by at least 40% compared to the 1990 level, the Republic of Croatia does not have such an ambitious plan. In the time when wind plants and photovoltaic systems represent a relatively cheap energy technology, this paper will analyse the influence of construction of wind and photovoltaic power plants in order to present the optimal constructing ratio of such systems on the Croatian power system load. Simulations have been conducted in the EnergyPLAN model for the year 2012. After choosing several promising scenarios, applying the Pareto analysis will show the best scenario for generating electricity from renewables, scenario with the lowest import of electricity, scenario of CO2 emission and with the lowest critical excess electricity production. Finally, all of the scenarios will be subjected to a multiple criteria decision analysis in order to find the best overall scenario. The best overall scenario was 1.65 GW of Wind power plants and 1.6 GW of installed PV capacity, which proved that PV will have a bigger role in the Republic of Croatia than expected.
