Flexible market trading strategy for business integrated energy users considering energy cascade utilization.

With the rise of the energy Internet and the reform of the power market, the multi-energy collaborative trading mode plays a fundamental role and acts as the framework in the construction of the integrated energy market. An integrated energy system model and its trading market mechanism are built in this paper. A new transaction strategy in the system is proposed to solve the problem of cascade utilization of thermal energy and flexibility of future market relationships. To facilitate the role transformation of stakeholders, the multiple agents system is used to decouple the complex relationship of the market transaction into two Stackelberg games of "two leaders and one follower". In addition, The Lagrange multiplier method is used to optimize the objective function and the optimal result is obtained by continuous iteration, and the existence and uniqueness of Nash equilibrium are verified. Eventually, The simulation results validate that the model has greater benefits for all stakeholders, new energy consumption and environmental protection. • The trading strategy proposed solves the flexible trading of multiple energies. • Decoupling the multi-energy market transaction into two Stackelberg games models. • The existence and uniqueness of Nash equilibrium in transaction model are verified.
