Yra 寞vertinami ne tik hybridinio parko Lietuvoje prana拧umai, bet taip pat ir silpnosios bei sud臈tingosios pus臈s. Rezultatai parod臈, kad hibridiniai parkai gali reik拧mingai padidinti energijos tiekimo patikimum膮, suma啪inti priklausomyb臋 nuo importuojamos energijos ir efektyviau i拧naudoti infrastrukt奴r膮.

This paper examines the possibilities of developing a hybrid park in Lithuania that would combine three different energy sources in one substation - electricity generated by wind turbines, electricity generated by solar panels and a storage unit that would store excess energy and supply it to the grid at a selected peak times. It is also designed a 70 MW wind, 95 MW solar and 20 MW battery hybrid park and calculated capital expenditure, operational expenditure, annual production and levelized cost of electricity, while using publicly available data. The aim of the study is to assess the practical value of such a park and analyze the prospects for its implementation in the Lithuania's energy context. Not only the advantages of a hybrid park in Lithuania are assessed, but also its weaknesses and complexities. The results showed that hybrid parks can significantly increase the reliability of energy supply, reduce dependence on imported energy and use the infrastructure more efficiently.

The aim of this master thesis is to develop and test a model based on GIS (Geographical Information System) and multi-criteria analysis techniques to find potential sites for solar power plants. Site searches are influenced by many factors (e.g. environmental, legal, political and social factors), and therefore it is not efficient to use classical analytical tools and methods (e.g. AHP or ELECTRE) alone. Combining several different approaches provides the optimal result. GIS is a tool that simplifies the search for the location of solar power plants by incorporating technical, legal, political and environmental criteria (e.g. solar radiation intensity, local topography, environment, including the nearest roads, lines, their capacity and distance to substations). Once the technical, legal, political and environmental criteria have been evaluated and data collected on how they determine the choice of a site, an all-in-one model-tool can be developed using GIS input parameters (e.g. solar radiation time series, digital elevation models) for the purpose of siting solar power plants. The thesis consists of the following parts: introduction, theory, methodology, data analysis and research, summary, reference list, appendices. The thesis consists of 57 pages without appendices, 5 diagrams, 15 tables, 41 figures, 47 bibliographic sources Appendices are added after the bibliography
