SDP-based Optimal Power Flow with Steady-State Voltage Stability Constraints

This paper proposes a voltage stability-constrained optimal power flow (VSC-OPF) model based on semidefinite programming (SDP) relaxation. The minimum singular value of the power flow Jacobian is used as a steady-state...

System Dynamics Modeling Of Socioeconomic Development Mode Associated With Water Usage In Baiyangdian Lake, Northern China
With continual increase of environmental pressure from human activities, it has become necessary to study the process of socioeconomic water usage influencing the water quality. Based on the system dynamic model developed before...
Optimization of Cogging Torque Based on the Improved Bat Algorithm
Wenbo Bai, Huajun Ran
Dec 21, 2022
Permanent magnet motors have the advantages of high output torque, high efficiency, and low noise, but the cogging effect is obvious. The 24-slot 4-pole surface-mounted permanent magnet synchronous motor is taken as an example...

Information Usefulness and Attitude Formation a Double-Dependent Variable Model (DDV) to Examine the Impacts of Online Reviews on Consumers
With the popularity of online shopping, a large body of studies have paid much attention to the factors influencing consumers’ information seeking and assessing. However, theoretical development and empirical testing are still...
Design of Metal-Free Polymer Carbon Dots
Polymer carbon dots (PCDs) are proposed as a new class of room-temperature phosphorescence (RTP) materials. The abundant energy levels in PCDs increase the probability of intersystem crossing (ISC) and their covalently...

Vibrational density of states of amorphous solids with long-ranged power-law-correlated disorder in elasticity.
Bingyu Cui, Alessio Zaccone
Nov 26, 2020
A theory of vibrational excitations based on power-law spatial correlations in the elastic constants (or equivalently in the internal stress) is derived, in order to determine the vibrational density of states D([Formula: see...
