Renewable energy bases are typically in uninhabited, dry, and windy areas. These highly susceptible to dust impacts due the atmospheric environmental changes brought about by recent rise global temperature. Since 2023, influenced meteorological changes, China's northwest northeast regions have experienced fourth large-scale storm event. However, widely used line thermal balance equations still need be restructured model conditions of renewable bases, leading overly optimistic conclusions...
This paper presents a power swing detection algorithm in multi-machine systems, which uses wide-area synchrophasor measurements and is based on Zubov's stability boundaries. boundary method, an approximation of the famous Lyapunov function, very common for numerical analyses system stability. work extends concept boundaries to online protection applications. First, proposed constructs series angle-frequency (δ-ω) plane generators real-time from phasor measurement units/merging units. Then,...
Abstract In this work, we study the Dirichlet problem for a class of degenerate elliptic equations with singular potential on conical manifolds. By using cone Sobolev inequality and Hardy inequality, existence nontrivial solutions has been proved.
The centralised utility-scale photovoltaic (PV) plants installation has greatly enlarged their percentage in the bulk power systems, along with nature uncertainty for balance of system and loads. Consequently, successful integration solar PV large-scale systems requires a reliable efficient multi-area automatic generation control (AGC) within centre. Specifically, area-AGCs that perform tie-line bias control, which area frequency regulates flow, must operational supply power-and-demand loads...
The present paper is concerned with the existence of multiple solutions for semi-linear corner-degenerate elliptic equations subcritical conditions. First, we introduce corner type weighted p-Sobolev spaces and discuss properties continuous embedding, compactness spectrum. Then, prove Sobolev inequality Poincaré inequality, which are important in proof main result.
Operation state calculation (OSC) provides safe operating boundaries for power systems. The operators rely on the software-aid OSC results to dispatch generators grid control. Currently, workload has increased dramatically, as structure expands rapidly mitigate renewable source integration. However, is processed with a lot of manual interventions in most dispatching centers, which makes error-prone and personnel-experience oriented. Therefore, it crucial upgrade current an automatic mode...
Abstract In this study, magnetic Mg/Fe hydrotalcite calcined material (M-CHT) was synthesized through the co-precipitation and calcination method, used to effectively remove nitrate nitrite from water. M-CHT can restore its original layered structure after adsorption of or nitrite, be easily separated by an applied field. The first-order pseudo-second-order kinetic models (R2 ≥ 0.97) better describe process. equilibrium isotherm showed that Langmuir model provided a fit experimental data...
Abstract In this paper, we consider the stochastic evolution equation driven by Gaussian noise with white time and colored space, where coefficient is Marchaud fractional derivative. The key idea that transform our model into a space-fractional taking derivative, then use Chaos expansion to prove mild solution. There are three main results in paper. First, apply obtain existence, uniqueness Lyapunove exponent of solution transformed equation. Second, there exists an unique original equation,...

We first give preliminary of framework and then discuss weighted type Hardy inequality. By using variational method, we prove existence multiple solutions boundary-value problem.
