The purpose of this thesis is to examine and present the oportunities of solving control problems using Modelica. This is done by creating some demonstration examples with exercises. These examples should cover as many types of control problems as possible. The exercises are aimed for people with basic knowledge in modeling and automatic control engineering but with little or no knowledge in Modelica. There are different types of Modelica implementations and the ones used in this thesis are OpenModelica and MathModelica.

This work is in the introduction focused on the introduction of technologies for electrical energy storage, their description and capturing the main advantages and disadvantages. After this capture follows comparison of the various technologies in terms of efficiency , discharge time and the price for1 kWh . Following section focuses on electrochemical model VRB batteries , which describes the equations describing the behavior of a battery depending on the chemical an electrical properties . In the penultimate chapter, I introduced the language of object- oriented modeling language Modelica and the most common programs based on it, including a short introduction for modeling in MathModelica. The last part deals with the modeling of specific VRB battery, which we have at the faculty.
