Economic Dispatch of Offshore Oil and Gas Platform Group Based on Electricity-Gas Shared Energy Storage

The access of shore power has brought a new energy structure to the offshore oil and gas platform group. In order to further reduce the operating cost of offshore oil and gas platform groups, this paper proposes an economic dispatch model for offshore oil and gas platform groups based on electricity-gas shared energy storage. First, the energy structure of the offshore oil and gas platform group is analyzed, and the load model of the oil and gas production unit is established. Then, the mathematical model of the energy storage device is constructed and the electric-gas shared energy storage mode is proposed. Finally, an optimal scheduling model is established with the goal of minimizing the running cost. Taking an oil and gas platform group in the Bohai Sea as an example to simulate, through the analysis and comparison of three scenarios, the effectiveness of the model in this paper in reducing the configuration of energy storage capacity and reducing operating costs is verified.
