Problems solved by technology
However, the dynamic process time scales of the electric and thermal energy subsystems in the system are quite different, and it is impossible to achieve optimal scheduling within the same time scale
If only the thermal energy transfer is idealized without thermal delay, there is a gap with the actual situation
In addition, the industrial park contains a variety of energy-consuming subjects, and the load demand is large, but the energy utilization efficiency is low, resulting in insufficient power supply to the energy-consuming subjects

The invention discloses an energy system multi-time-scale interactive optimization operation method and system. The optimized operation method comprises: establishing a heat supply model of a heat supply pipe network in an actual heat supply system according to the heat supply data; according to the heat supply model, determining the delay time of the transmitted heat compared with the same-periodtransmitted electric quantity; establishing an electric load model and a thermal load model of a load side user; establishing an operator model according to the operation state of the energy system;determining a benefit function of the user, determining the benefit function of the operator according to the operator model, and obtaining the user benefit function and the operator benefit function;and establishing a game model by adopting a game theory according to the user benefit function, the operator benefit function and the delay time, and obtaining a game strategy corresponding to the maximum benefit of the user and the operator according to the game model. A game model is established through the game theory, and game balance can be achieved on the premise that the profits of operators and users are maximized.
Description
technical field [0001] The invention relates to the field of energy, in particular to a multi-time-scale interactive optimization operation method and system for an energy system. Background technique [0002] The integrated energy system can realize the scientific dispatch of various energy sources in the system, realize the efficient use of energy, effectively alleviate the current energy problems and alleviate the energy crisis. However, the dynamic process time scales of the electric and thermal energy subsystems in the system are quite different, and it is impossible to achieve optimal scheduling within the same time scale. If only the thermal energy transfer is idealized without thermal delay, there is a gap with the actual situation. In addition, the industrial park contains a variety of energy-consuming subjects, and the load demand is large, but the energy utilization efficiency is low, resulting in insufficient power supply to the energy-consuming subjects. There...
