Abstract: At present, the human-free and low carbonization of offshore oil and gas platforms has become a development trend. In order to meet the low-carbon operation of unmanned oil and gas platforms, this paper constructs an offshore oil and gas micro energy system considering the access of renewable energy to realize the low-carbon operation of offshore oil and gas platforms. Firstly, considering the uncertainty of renewable energy, a hybrid energy storage system is constructed, which consists of a low carbon operation module of floating power to gas-associated gas storage（FP2G-AGS）, and an offshore oil and gas micro energy system with renewable energy access and hybrid energy storage system is established. Secondly, considering the matter-energy flow of the system, a heterogeneous flow coupling model is established, and the coupling relationship of each system unit is analyzed. Considering the uncertainty of source and load, a stochastic fuzzy economic optimal scheduling model is constructed to realize the coordinated optimization of the system. Finally, the feasibility and effectiveness of the proposed model and method are verified through numerical simulation.
