Resumo(s)
The electrical energy is a contemporaneous paradigm, the demand for electrical energy is evergrowing,
and so is the energy supply; By bringing the energy production closer to the end-users,
either in urban centers or people in remote areas have a chance to exploit renewable energy
resources to produce electrical energy, and become self-sufficient. Hydropower has since long
been a reliable power source, as well as being the most cost-effective. Although, it has its issues,
e.g., its synchronization to the utility grid depends on the continuous operation mode of the
generator.
Commercially available low-power inverters, up to 1.5 kW, are designed to be applied in
either solar power generation, or wind power generation. These inverters were not designed
to be used with hydropower generation. This work evaluates two current-controlled power
interface solutions, boost and C´ uk converters, to make a hydropower generator and a commercial
photovoltaic inverter compatible.
The models, simulations and tests of the proposed power structures along with a commercial
photovoltaic inverter emulation are made with Matlab® Simulink®, facilitating the evaluation
of the power structure and its controller in a discrete-time domain in a Simulation-in-the-Loop
environment, as well as, an implementation using a Real-Time controller board from dSPACE
interfacing between the power structure and the controller built-in Simulink® in a Hardwarein-
the-Loop test platform with Commercial Phtovoltaic Inverter (CPVI), which allows for
rapid prototyping, data acquisition and processing and experimental validation of the proposed
solutions.
