AI Technical Summary

Problems solved by technology

[0009] Disadvantage 1 of the existing technology: Traditional reliability improvement algorithms mainly focus on improving the reliability of the power system, but with the introduction of multiple coupled energy sources, the reliability improvement of the power system that can only evaluate electric energy is no longer suitable for comprehensive energy with multi-energy conversion Improved system reliability

[0010] Disadvantage 2 of the existing technology: The existing technology regards the operation of the integrated energy system as two states, that is, complete failure or perfect operation, and does not consider the intermediate state of the operation of the integrated energy system. Insufficient, so that the obtained reliability improvement model cannot accurately reflect the reliability of the integrated energy system

[0011] Disadvantage 3 of the existing technology: When improving the reliability of the integrated energy system in the existing technology, it often faces the problem that the system scale is enlarged and the reliability calculation time is also increased sharply, thus reducing the practicability of the reliability improvement algorithm, and accurate calculation is often incompatible with Fast calculations cannot simultaneously satisfy
