Power interface for grid-connected pico-hydro systems using PV inverters
Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do Paraná ; 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.
