Abstract
In order to ensure the stable energy supply for isolated island areas scattered around the globe, a reliable and flexible energy supply system, and corresponding efficiency and intelligent energy management strategies are indispensable. In this paper, power to gas(P2G) is introduced to promote the absorption of distributed renewable energy, and facilitate the deeply coupling of electric–gas networks in multi-energy complementary energy system. Besides, considering the inherent characteristics and actual coupling situation of each module, six possible cooperative game and non-cooperative game schemes are proposed, under the fixed time-sharing electricity price mechanism and dynamic incentive electricity price mechanism, to compare the differences in energy utilization efficiency, pollution emission level and total revenue. The final study results show that under the two price mechanisms, the synergetic response of fuel cell and gas turbine makes the curtailment rate of distributed renewable energy decreased by 5.68% and 3.76% respectively, and the output share of DG decreased by 5.77% and 7.36% respectively. It has realized efficient utilization of energy and emission reduction of pollutants. In terms of revenue, the cooperative game mode with dynamic electricity price mechanism increases the total revenue of the system by 25.02%.
