The stability and robustness analysis of SNG and PNG supply

Abstract Current researches on dynamic analysis of energy supply mainly (1) Chaotic control of supply process. (2) Resource synchronization in supply process. (3) Dynamic behavior of energy supply under the influence of parameter perturbation. However, in above researches, the disturbance type is not described and classified. In addition, none of the three approaches addresses the stability of the energy supply. In order to improve the above methods, in this paper, the stability analysis method of energy supply process is firstly proposed, this method can judge whether the deterministic energy supply system is stable at different times. However, the disadvantage of this method is that it is suitable for non-chaotic deterministic systems, but internal and external disturbances of the energy supply will make the supply system unstable and fall into chaos. So we classify the types of disturbances, give robustness of the system under different disturbances, and help company design energy supply system and select the system parameters with good robustness to analyze stability of energy supply process. • The internal and external disturbances of the system are classified and discussed. • Proposed the concept of robustness of energy supply system, and give the method to judge the robustness of the system.
