Akumulace elektrické energie získané z obnovitelných zdrojů.

Abstract

In this work, I solved the problem with an emerging generation of electricity from renewable sources, which is irresponsible and undermines the operation of the elecrical network. Suitable storage element will accumulate the energy produced from renewable sources, which adds to the network if necessary. The aim is to select a storage system using multicriteria analysis. I chose the two calculation methods, because I wanted to point out how it can affect the calculation method chosen calculation. Result is mildly different. Methods vary both the method of calculation, but also the chosen method of comparing weights of criteria.The best storage element calculated using multi-criteria analysis is supercapacitors, which appears as objective as possible. I also dealt with the possibility of combining multiple storage elements. When one element of an instant supply of electricity to the grid if necessary, and the second term will ensure delivery of the order of hours. On the accumulation of electrical energy from renewable sources in the future will take more and more attention. Not only can use energy storage to ensure the supply network, but enegii used for production of hydrogen and subsequent use of hydrogen as a fuel in the automotive industry.
