The control of energy production system created from fuel cell and different solar panels via microcontroller

Abstract

In the study, the energy that monocrystalline, polycrystalline and thin-film solar panels of equal power produce was combined on the electronic board and hybrid solar system was created. Fuel cell was added to this hybrid system, so providing diversity in energy production sources. The produced electrical energy flow was controlled by using different energy sources types together. Battery groups were connected to the control circuit for storing the produced energy. Also, the receiver loads, which would redirect the flow energy were added to the control circuit. The electrical energy each solar panel produced, the electric current the load pulled and battery charge-discharge conditions were monitored through the control system designed to control the flow energy. These data were recorded at regular intervals with C# software. The control algorithms that are appropriate for system’s energy flow were determined and consumers were fed with the electrical energy produced by the hybrid system, and the battery was charged at the same time. The recorded data were analyzed and the energy each solar panel produced, the rates of benefiting from produced electricity through applied algorithms, and how much consumers were fed with the energy accumulated on the battery group were approximately determined.

Predictive Control Applied to a Single-Stage, Single-Phase Bidirectional AC-DC Converter

“…There are several energy sources that can be interconnected to the system in the context of distributed generation and microgrids. The most widely used renewable sources nowadays are wind turbines and photovoltaic modules and, owing to their intermittent nature, their combination with other energy sources and batteries is an interesting solution to increase the reliability of the continuous energy supply [1], [2]. Another trend in distributed generation is the use of electric vehicles (EVs) with bidirectional chargers which present grid-to-vehicle (G2V) and vehicle-to-grid (V2G) functions [3].…”

Robust control of a DC-DC three-port isolated converter

“…The last few decades have witnessed an increasing interest in renewable energy systems, creating the need for the use of integrated converters capable of interfacing and simultaneously controlling various power sources. Wind generators and photovoltaic panels are two of the most important renewable sources and, due to their intermittent nature, their combination with other power sources is necessary to increase the reliability of the continuous power supply (Karakan et al, 2019;Noghreian and Koofigar, 2019;Spier et al, 2019).…”
