Problematika akumulace elektrické energie z FVE

Abstract

Photovoltaics occupies an important place in the field of renewable resources and is increasingly an integral part of the electricity system in the Czech Republic. Between 2009 and 2010, a large number of photovoltaic power plants were built as part of advantageous economic incentives, which supplemented the capacity and strengthened the reliability of the electricity system. Currently, with rising energy costs, this industry is booming again. As of 31.12.2023, the achievable output of photovoltaic power plants was 3.45 GWp with a total of 167360 PV plants [23]. Interest is mainly in rooftop installations, which was triggered by subsidies for families and companies in combination with rising energy prices. Photovoltaic power plants contribute to the energy grid only during daylight in direct proportion to the exposure of photovoltaic panels. The instantaneous output of a photovoltaic power plant is therefore dependent on the weather. In order to maintain the balance between production and consumption in the electricity system to the maximum extent, it is necessary for photovoltaic power plants, as one of the renewable energy sectors, to supply the generated energy to the grid regularly and without outages. We cannot influence meteorological conditions, but we can contribute to the stability of electricity supply to the electricity system by eliminating extraordinary power outages, i.e. by increasing the continuity of electricity supply to the electricity system.

In the first theoretical phase, this thesis deals with the analysis and evaluation of the spectrum of accumulation systems. In the second part, the author of this thesis is the evaluated foreign publication on the topic of photovoltaics. In the third part of the thesis, the thesis deals with the use of multi-criteria MCA analysis to evaluate the optimal solution of electricity storage from PV plants. The fourth part describes possible key faults on the PVPP and fault analysis using MCA. The fifth part deals with the analysis of battery systems for electricity storage. In the sixth part of the thesis, the problem Elimination of power outages to DS. The thesis is finished with a final evaluation.
