Multi-energy coupling low-carbon optimal operation of sea-land interconnected off-grid microgrid

Offshore oil and gas platforms produce a large amount of carbon dioxide, this paper introduces a carbon capture device combined with new energy output to reduce carbon dioxide and environmental pollution. The stability of power supply is especially important after the new energy is connected to the platform, so additional land energy terminals are installed to ensure the power supply, and energy storage devices and hydrogen fuel cells are used to smooth out the fluctuation of new energy output and reduce the abandonment of wind and photovoltaic. Then an off-grid microgrid integrated energy system model integrating offshore oil and gas platform group and land energy terminal is established, and the internal energy flow of the system is analyzed. Finally, a low-carbon optimization model for microgrids is developed, and the example shows that the proposed model reduces carbon emissions and improves economic efficiency at the same time.
