Eliminace zpětných vlivů OZE s využitím akumulace

Abstract

This bachelor thesis deals with the back influences of renewable sources, especially photovoltaic power plants, on the distribution system. The aim of this work is to eliminate these back influences by using an accumulative device of electric power. It primarily covers the accumulation of electric power via accumulators. The first chapter defines the negative back influences by which the photovoltaic power plant can affect the distribution system. It also defines the requirements on quality of electric power from the perspective of the individual parameters. The next chapter is dedicated to accumulation of electric power, especially via accumulators. The most used batteries and their advantages and disadvantages for the individual types of accumulations are being described here. This entails two types of accumulations, namely output and energetic accumulation with potential output balance solution of the access point of the photovoltaic power plant into the system. The summary of the paper provides an evaluation with subsequent recommendation of usage of the individual types of accumulators for the given type of accumulation.
