Research on the control of photovoltaic power generation system for arctic field monitoring devices

Because of the current situation that the Arctic field monitoring device drifts with the sea ice all year round and mainly relies on battery power supply, this paper proposes a control strategy for the Wind, light and sea current power supply system, which is the central power generation unit in the scenic sea current power supply system, using an improved adaptive variable-step maximum power tracking to ensure the tracking speed and steady-state accuracy; when the input power is redundant, the constant voltage control bus voltage is used to safeguard The two control methods and their switching processes are simulated using Matlab/Simulink for the photovoltaic power generation system at low temperature. The simulation verifies that the control strategy can make the photovoltaic power generation system under the sudden change of environmental conditions stable and controllable output.
