The study analyzes the effective dynamical system combining degenerate additive noise-driven stochastic partial differential equations, firstly in the first class of stochastic partial differential equations, the terms in the non-nuclear space formed by nonlinear interactions are overcome by effectively replacing the elements in the non-nuclear space through the It\u00d4 formulation, and thus the final effective dynamical system is obtained. The effective dynamical system is then obtained in the second type of stochastic partial differential equation using the O-U process similar to the terms in the non-nuclear space. At noise disturbance amplitudes of 5%, 10%, 15% and 20% AC voltage maxima in that order, the effective dynamical systems for the first type of stochastic partial differential equation and the second type of stochastic partial differential equation are more stable compared to the other types of partial differential equation dynamical systems, with the maximum range of error rate improvement for the sampling points 0\u2013239 voltage rms and voltage initial phase value being 3.62% and 26.85% and 2.13% and 19.86% for sampling points 240\u2013360, respectively. The effective dynamic system and stochastic partial differential equation obtained by the research have very high approximation effect, and can be applied to mechanical devices such as thermal power machines.<\/jats:p>","DOI":"10.3233\/jcm-226914","type":"journal-article","created":{"date-parts":[[2023,6,20]],"date-time":"2023-06-20T11:29:32Z","timestamp":1687260572000},"page":"2645-2657","source":"Crossref","is-referenced-by-count":0,"title":["Noise-driven signal study of power systems based on stochastic partial differential equations"],"prefix":"10.66113","volume":"23","author":[{"given":"Yanfen","family":"Chen","sequence":"first","affiliation":[]}],"member":"55691","reference":[{"key":"10.3233\/JCM-226914_ref1","unstructured":"Setayeshgar L.
