Operation Optimization of Offshore Oil and Gas Interconnection Energy System Based on ADMM

With the increase of various types of offshore loads, the traditional energy supply method can hardly meet the demand. In order to further optimize the energy supply method, this paper proposes an operation optimization method of offshore interconnected energy system considering new offshore energy sources and energy storage devices. First, a mathematical model of various types of energy equipment is constructed. Then, based on the synergistic sharing of electricity and gas energy substances, the operation cost model of a single energy system and the synergistic optimized operation model of multiple energy systems are established and solved by the ADMM (alternating direction multiplier method). Finally, the proposed model is verified to be effective in reducing the operation cost of individual oil and gas production units and the whole oil and gas platform group through the simulation analysis of calculation cases.
