The definition of input parameters for modelling of energetic subsystems

Abstract

Summary. -This paper is a short review and a basic description of mathematical models of renewable energy sources which present individual investigated subsystems of a system created in Matlab/Simulink. It solves the physical and mathematical relationships of photovoltaic and wind energy sources that are often connected to the distribution networks. The fuel cell technology is much less connected to the distribution networks but it could be promising in the near future. Therefore, the paper informs about a new dynamic model of the low-temperature fuel cell subsystem, and the main input parameters are defined as well. Finally, the main evaluated and achieved graphic results for the suggested parameters and for all the individual subsystems mentioned above are shown.

The cooperation of fuel cells and renewable energy sources: A short review of operated energetics systems and their main deficiencies of PEMFC models in hybrid systems

“…individual types of energy sources, lines, transformers, and other electrical devices) and each used subsystem in the model has to be described, simulated and evaluated separately. Moreover, the same hybrid concepts can be simulated in a different way and mathematical simulation of the fuel cells is a very complex and extended matter because it has to respect a lot of interconnections among many different disciplines [2]. It is the reason why the mathematical models are created by various software and the simulation can be solved by many approaches.…”

“…Moreover, it seems that an installation of the renewable energy sources can be useful for the environment. Thanks to this fact, the share of the renewable energy sources in the European distribution and transmission networks significantly increases every year [2].…”
