Multi-energy pricing strategy for port integrated energy systems based on contract mechanism

This article studies a pricing scheme to increase the profit of ports and gas utility company (GUC), and improve social welfare. Firstly, a system model of the port integrated energy system (PIES) is established and the government green subsidy on biomass gas is considered. Secondly, a multi -stage game is formulated to characterize the interaction between the port, GUC and the government. Besides, the contract mechanism is used to improve the operation performance of the energy supply chain. Then, the equilibrium solutions of the game are obtained by the backward induction. Finally, the theoretical analysis and simulation show that the proposed pricing strategy can improve the profit of GUC, ports and government, and the proposed revenue sharing contract mechanism can coordinate the energy supply chain.
