| Abstract [eng] |
Evaluation of effective controlling system of solar power plant as a scien-tific problem is discussed in dissertation. Object of research – methods of load resistance changing and adaptation of algorithms of maximum power point tracking under different environmental conditions of solar power plants. Goal of the thesis is to create and investigate the method of maxi-mum power point tracking which allows to increase the efficiency of solar power plant under fast changing environmental conditions and improve the method of load resistance changing. Created and investigated models of solar power plant efficiency with maximum power point tracking system. Proposed methodology which allows to increase the efficiency of maximum power point tracking algo-rithm of solar power plant. The influence of changing environmental condi-tions on solar power plant was investigated, the effective methodology for changing load resistance of solar power plant was proposed. Dissertation consists of introduction, three chapters, general conclu-sions, lists of references and author‘s publications on the subject of disser-tation and summary in English. The introduction reveals the investigated problem, importance of the thesis and the object of research and describes the purpose and tasks of the dissertation, research methodology, scientific novelty, the practical signifi-cance of results examined in the paper and defended statements. The intro-duction ends in presenting the author’s publications on the subject of the defended dissertation, offering the material of made presentations in con-ferences. Reviewed literature is provided and the solar power plant development trends is revised in the first chapter. Reviewed solar power plant operating performance under rapidly changing environmental conditions. At the end of the chapter, conclusions are drawn and the tasks for the dissertation are reconsidered. The second chapter describes implementation of a mathematical model in Matlab®/Simulink®. The implemented mathematical model allows to sim-ulate various operating conditions of solar power plant: different solar pow-er flux, module temperature or different maximum power point tracking algorithms. The third chapter, investigates solar power plant operation under unpre-dictable environmental conditions using the created mathematical model. Investigation is splitted into separated phases. Six articles are published on the subject of dissertation: two – in scien-tific journals included in Thomson Reuters Web of Knowledge list Web of Science, four – in scientific journal listed in other international databases. Nine presentations were presented in scientific conferences. |
