Micro energy grid is the development direction of the terminal energy supply of the energy Internet (EI). The economic optimization of the system urgently needs to tap the potential of multi-energy loads, and a single demand response cannot meet the coordinated optimization of “source-network-load”. In this paper, aiming at the coupling conversion characteristics of multiple energy sources in the micro energy grid, a generalized energy hub model including energy storage and integrated demand response (IDR) is established. Energy operators of micro energy grid are introduced and three comprehensive demand response models, namely, transfer model, transforming model and reduction model are established. A day-ahead optimization scheduling method for micro energy grid considering comprehensive demand response is proposed, in which time-of-use energy prices are formulated, three demand response modes are coordinated and optimized. A mixed integer linear programming model with the goal of profit maximization is established, and the solution is solved by CPLEX software. Combined with a calculation example, the effectiveness of the comprehensive demand response model and the day-ahead optimal dispatching method proposed in this paper is verified. Results show that the multi-energy load coupling and complementary capabilities of the micro energy grid are maximized, and the economic efficiency of system operation is improved.
