Smart Energy Storages for Integration of Renewables in 100% Independent Energy Systems

摘要: Primary energy import dependence of the European Union is currently around 53%, and it expected that in next 20-30 years will reach or surpass 70%. The situation Croatia similar. In 2007 was 53.1%, while for 2030 predicted to 72%. Such leads decreased security supply, due current geopolitical which main sources fossil fuels are unstable regions competition those resources from developing countries growing. EU strategy, a compatible Croatian focused on policies measures bring increase share renewable distributed sources, efficiency savings decrease green house gas emissions. results previous research has shown order viability, there need storage, primary secondary form, transfer surplus form period excess when lack. problem storage systems they cost already expensive making them, market circumstances, even less economically viable. Although number technologies, as chemical, potential heat energy, not all technologies optimal each system. paper shows planning several cases where use smart system could help with integration flows, transformations demand at location enduse close it.
