Abstract
As the realization form of integrated energy system, integrated energy park is the key research object in the field of energy. Actual integrated energy parks are often partitioned internally. In order to take into account the interests of each zone in the optimal scheduling of integrated energy parks, a double-layer optimal scheduling model of integrated energy parks based on non-cooperative game theory is proposed. First, according to the operation of the integrated energy park, the output and cost model of the park is established. Second, with the minimum daily cost as the upper layer objective and the highest energy efficiency of the cogeneration system as the lower layer objective, a double-layer optimal scheduling model is established. Then based on non-cooperative game, the optimal operation strategy of each zone is obtained through the game among all the zones. An integrated energy park is taken as an example, the results show that the proposed model can make zones adjust their operation strategies more reasonably, thus helping to reduce the cost of the park and improve energy efficiency.
Highlights
With the increasing demand for energy and the accelerating development of urbanization, the contradiction between the energy demand of human society and the endurance of the environment has become increasingly prominent
In such a global environment, integrated energy system emerges as the times require, as the physical carrier of energy internet; it has been well known in academia and business circles [4,5]
The day-ahead optimal scheduling of integrated energy system is an important link to ensure the optimal operation of integrated energy park
Summary
With the increasing demand for energy and the accelerating development of urbanization, the contradiction between the energy demand of human society and the endurance of the environment has become increasingly prominent. In literature [12], a new day-ahead optimal dispatching model for P2G storage and gas load management in power and natural gas markets is proposed to minimize the gas consumption cost of gas load. Most of these literatures have focused on the lowest operating cost, the best environmental protection, or other objectives, and have made in-depth studies on the day-ahead optimal scheduling of an integrated energy system. An integrated energy park is taken as an example, and the results show that the proposed model can make zones adjust their operation strategies more reasonably, helping to reduce the cost of the park and improve energy efficiency
