Complex simulator of the solar irradiance
Petrov, Roman ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This work consists of a theoretical part, which deals with various ways of mathematical equations to model the thermal photovoltaic cell. Thermal modeling describes a photovoltaic cell temperature, and heat capacity of the photovoltaic cell. This temperature is usually function or directly dependent on the intensity of solar radiation. In the theoretical section explains several ways to model thermal photovoltaic cells. Thermal modeling is outside the scope of this paper, it is mainly the modeling of solar irradiance, which is discussed in detail in the next section, and then in the practical part. The practical part is concerned with constructing mathematical equations that describe the intensity of solar radiation. These mathematical equations are then used to build a mathematical model. The actual mathematical model is created in a computer program PSCAD, wherein the main input parameter of the intensity of solar radiation. This model can simulate the course of the sun, for which it is necessary to set various parameters such as: region, time of day, the seasons, but also has a function that is essential for modeling of solar radiation intensity, and it is cloudiness. Cloud is fundamentally changing the size of the radiation intensity, and its direct constituents. After compiling a complex simulator of solar irradiance, this simulator is tested for its validation in form of doing couple of graphical runs of intensity of solar radiation for various locations on Earth, which are time dependent.

Development of the complex simulator of the solar irradiance and its cooperation with the PV module
Petrov, Roman ; Vrána, Michal (referee) ; Ptáček, Michal (advisor)
The main point of this thesis is the extension of the complex solar radiation simulator, the creation of new functionalities, and the cooperation of this complex simulator with the PV power plant. This work builds on the work done in the area of solar radiation modeling. The thesis deals with the continuation, or improvement of some shortcomings, removing shortcomings, such as fixing the beginnings and ends of the simulation, correcting the calculation of sunrise and sunset, but also adding different types of clouds, combinations of different preset cloud situations, or data input, and more. These deficiencies are found in the bachelor's thesis "Complex Simulator of the solar irradiance", and PSCAD is the main tool in this work. Another important point of this work is the realization of the simulation where an improved solar radiation simulator works in cooperation with a model of a photovoltaic panel or a PV power plant, respectively. It has different operating states created in PSCAD. These include, for example, cloud crossings, both over the entire power plant and only partial. In addition, there are experiments that prove the fact that the direction of the incoming cloud plays a role in the power of the PV power plant.
