A study of regenerative energy systems and PUMP applications in distributed DC-microgrids

The concept of distributed energy generation in DC-microgrids is becoming more and more popular, due to the enhanced advantages of energy self-supply and minimizing of conversion losses. Based on a sewage application containing a photovoltaic system and a pump application, this paper describes the individual subsystems of a DC-microgrid. A Matlab/Simulink simulation will be presented to view the behaviour of the system with its power flows and potential of optimization. The validation of the simulation model is verified by an experimental setup and the simulation and measured results will be compared.
