Problems solved by technology
[0004] Most of the existing technologies are aimed at the optimal dispatching of a single regional integrated energy system or the construction of an energy hub model. The complementarity and substitution between different energy sources have not been deeply explored, and there is a lack of dividing multiple single regional integrated energy systems into clusters. technology
At the same time, most of the existing evaluation systems only consider a single indicator, lacking the technology for comprehensive evaluation of indicators such as reliability, flexibility, and modularity.
In addition, since the introduction of the new power system reform plan, the power marketization process has been advancing rapidly among provinces, and other energy markets are also advancing steadily, which provides a reliable and stable platform for energy transactions in the integrated energy system and the realization of optimal social and economic benefits. platform, but there is limited research on the market participation of integrated energy systems in existing technologies

Embodiment Construction
[0062] In order to make the object, technical solution and advantages of the present invention clearer and clearer, the following references are made to the appended figure 1 Examples are given to further describe the present invention in detail.
[0063] Since most of the existing technologies are aimed at the optimal scheduling of a single regional integrated energy system or the construction of an energy hub model, the complementarity and substitution between different energy sources have not been deeply explored, and there is a lack of integration of multiple single regional integrated energy systems. technologies divided into clusters; evaluation systems mostly only consider a single indicator,
[0064] The invention discloses a cluster division of a regional comprehensive energy system and a method for participating in day-ahead market clearing, which can be used as a cluster by imposing a certain weight on the reliability index, the flexibility index, and the modularit...

The invention discloses a regional integrated energy system cluster division and participation day-ahead market clearing method, which considers reliability, flexibility and modularity indexes based on improved electrical distance as cluster division criteria, establishes a mathematical model of an electro-thermal coupled regional integrated energy system cluster, and takes social welfare maximization as an objective function. According to the method, the division method of the regional comprehensive energy system cluster and the optimal electric heating load demand of each regional comprehensive energy system cluster can be obtained at the same time. According to the method, complementarity and substitutability among different energy sources can be deeply mined, full consumption of comprehensive energy sources and optimal economic benefits can be achieved, and the application bottleneck that the overall utilization rate and economic benefits of a traditional energy system are not highis broken through.
Description
technical field [0001] The invention relates to the technical field of comprehensive energy systems, in particular to a method for cluster division of regional comprehensive energy systems and participation in day-ahead market clearing. Background technique [0002] With the rapid development of the energy industry around the world, the types of energy demand of users are becoming more and more diverse, and the energy supply system is becoming more and more complex. However, due to the large differences between different types of energy systems, traditional energy systems lack complementarity. Coordination and separate organization of the energy market have resulted in low overall utilization of energy and failure to achieve optimal economic benefits of energy. [0003] In order to reduce energy waste and achieve the optimal allocation of energy, in recent years, there is an increasing call to upgrade and transform the traditional energy system to form a regional integrated ...
