Problems solved by technology

[0004] At present, there are many methods for optimizing the dispatching of the integrated energy system, some of which consider the coordination of all energy sources in the integrated energy system to reduce output volatility, and some consider the energy quality to accurately reflect the operating status of the integrated energy system. It can be seen that the existing technology is only Provide optimal scheduling for the energy system through the supply of energy, but does not give an optimization method for the effective use of energy, and does not give a way to balance the load, so that energy scheduling and energy utilization are out of touch, and the maximum utilization of energy is not realized.

Abstract

The invention provides an optimal scheduling method, system and device for an integrated energy system, and a storage medium. The method comprises the steps of obtaining a predicted demand and a demand response parameter of each load in each scheduling region in a scheduling range, and parameters and output power of each device in the integrated energy system; adjusting the predicted demand of each load by using the load demand response elastic model; and substituting the adjusted predicted demand, the demand response parameter, the parameters of each device of the integrated energy system and the output power into a scheduling model taking the minimum daily operation cost as a target, solving to obtain a power output scheme of each device, and finding that the demand response can change the energy consumption habit of a user through the electricity price through result analysis. An electrical load curve obviously tends to be gentle, and the effect of peak load shifting is achieved; secondly, multi-region optimization is realized by taking the minimum daily operation cost as a target, so that the economical efficiency of the comprehensive energy system is effectively improved; and in addition, the program can be visualized through the GUI, so that the program can be better used by the user.

Description

technical field [0001] The present invention relates to the technical field of energy Internet planning, and in particular to an integrated energy system optimization scheduling method, system, equipment and storage medium. Background technique [0002] Energy is the basis for the survival and development of human society. Coal-based fossil energy has maintained economic and social development for a long period of time in the past, providing the foundation and power for the second industrial revolution, but it also affects the environment. Conservation poses serious challenges. Rapid economic development and material demand have led to a shortage of coal resources. Extensive energy consumption and pollution emissions in the past will also lead to environmental degradation and climate change. Therefore, how to rationally develop natural resources, develop renewable energy utilization methods, and sustainably develop modern society are issues of global concern. [0003] In t...
