Abstract:

The integrated energy system exchanges energy with the grid to meet the load demand within the system.Meanwhile,the energy consumption characteristics of the system aggravate the peak valley phenomenon of the power grid.In order to play the role of peak load regulation of integrated energy system,this paper introduces time of use price regulation strategy,which is used to optimize the output of equipment in different periods.It can not only meet the economic and efficient operation of the system,but also alleviate the peak valley contradiction of the power grid.To this end,the optimal scheduling model of the park system is constructed and solved in this paper,and the results obtained can guide the optimal operation of the integrated energy system.At the same time,in order to compare the similarities and differences between different methods,two types of typical methods,the mixed integer programming method and particle swarm optimization algorithm,are used to solve the problem,which can provide a reference for future research.

Key words: integrated energy system, time of use price, multi energy coupling, intra-day optimization
