Offshore oil-gas platforms in the same area are generally connected through the power grid and subsea oil-gas pipeline networks. It has formed a typical integrated energy system which interacts with multiple energy sources, water, electricity, gas and oil. However, the traditional energy management research mainly focuses on the stability control of the platform’s power network, and does not model the energy system of the platform group as a whole, which cannot reflect the characteristics of energy interaction between the platform groups. Therefore, this paper combs the current situation of energy utilization and operation control of offshore oil-gas platform energy system in a sea area of China, establishes the energy network of offshore oil-gas platform group, and puts forward the modelling, analysis and optimization method of offshore oil platform group. Firstly, focusing on the main energy coupling equipment (gas power station, gas heat station, electric heater,) of the platform, the energy efficiency analysis model is established to realize the energy efficiency diagnosis of the equipment. Then, based on the theory of Energy Hub, an electro-gas interaction optimization scheduling method is proposed to realize the optimization analysis of energy interaction between platforms. Finally, a calculation example of the actual platform group is given, which consists of three power generation platforms in China. The relevant research results will guide the closed-loop management of the operation, optimization and evaluation of the energy system. The application in the integrated energy management system of offshore oil-gas platform is helpful to improve the energy integration control of offshore oil platform.
