The Renewable Energy Laboratory at the Department of Electricity has modern equipment for research into the mutual influence of the current operation of hybrid photovoltaic power plants and the distribution system. The laboratory consists of a controllable direct current source, which simulates the operation of photovoltaic panels under various atmospheric conditions with a maximum output of 3 kW. The electrical energy produced from the photovoltaic panel model can then be stored in batteries or consumed in the form of a load. In case of insufficient capacity of energy produced from photovoltaic panels, or energy stored in batteries, the energy is supplied to the load from the external distribution network.
Subjects and outputs of education:
- Bachelor study: Subject Power plants – Testing the operation of power supply of the building from the distribution network and island operation (basic knowledge of electricity production in conventional and renewable energy sources)
- Bachelor study: Subject Faults in the power system (basic knowledge about changes in electrical parameters of overhead lines and their impact on short-circuit conditions, basic knowledge of operating networks, short-circuit calculations and their analysis in electrical systems at different types of symmetrical and asymmetrical short-circuits and ground connections )
To simulate the various boundary conditions that may appear in the distribution system, the laboratory contains a so-called artificial network. This device allows you to set a specific voltage level as well as the frequency of the distribution system with which the hybrid system works and examine their interaction in extreme operating conditions. Extreme conditions include, for example, loss and recovery of supply voltage from the distribution system, step changes in load, or operation of hybrid systems at different levels of network frequency.
The laboratory has one single-phase hybrid system from VONSCH, but it also allows testing of three-phase hybrid systems from various manufacturers.
