Power Distribution Control of PV-Diesel Power Systems

In this study, power distribution of a grid-connected hybrid power plant consisting of a 3.125 MVA diesel generator (DG) and 2 MW photovoltaic solar panels (PV) has been controlled. By using hourly solar radiation and temperature values of a day recorded in 2020, the power produced by PV has been instantly estimated with artificial neural networks (ANN). The diesel generator has been controlled according to the estimated values to obtain the required power produced by the diesel generator. As a result, using the proposed coordinated control methods, the total maximum power generated by the power plant is kept constant while decreasing fuel consumption.
