Problems solved by technology

Due to the diversified energy demand of multiple types of users in the integrated energy system, and the tight coupling and flexible conversion of different types of energy through energy equipment, it brings great difficulties to the planning and design of the system.

Most of the existing literature does not fully consider the interactive response characteristics of the energy supply side and the demand side in the comprehensive energy system planning, and the planning model does not fully consider the operation scenario simulation, so it is difficult to achieve the balance between the economy and robustness of the planning scheme. reasonable balance
