Description

technical field [0001] The invention relates to the technical field of integrated energy systems, in particular to a real-time simulation method and system for an integrated energy system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As the basis of human survival and development, energy has an important impact on the international political and economic structure. Traditional energy utilization methods mainly use fossil energy, which has problems such as extensive use process, low energy utilization rate, and serious environmental pollution. As a new generation of energy utilization, the integrated energy system integrates a variety of heterogeneous energy flows such as electric heating, which can give full play to the complementary advantages of different energy flows, and realize energy in different links of source-network-load-stor...

AI Technical Summary

Problems solved by technology

The inventors found that many integrated energy system projects that have been built have poor practicability due to the lack of relevant theoretical guidance in the early configuration and later operation, and cannot obtain the expected benefits in actual production; while at the level of theoretical research , most of the existing research results have only been verified in offline simulation, and cannot be directly applied in actual production

At the same time, with the deepening of follow-up research, people put forward higher requirements for the accuracy of optimization and control issues. In this case, ordinary offline simulation is more difficult to meet people's needs.

At the same time, the performance of the load and new energy in the integrated energy system has a strong dependence on the local weather and climate. The existing technology does not take the above factors into account when performing simulations, resulting in inaccurate simulation results.
