Analyzing the voltage stability of the smart grid requires accurate mathematical models of the load. Several static and dynamic load models were proposed, but most of them did not incorporate the frequency component. In order to build more accurate dynamic load models in the power system, we must examine the mathematical characteristics (short range versus long range dependence) of the power system...
Teaching electrical network control problems, such as droop control in power systems, is challenging (in part) because electrical systems are difficult to effectively visualize. Existing approaches do not generally provide students with an effective, intuitive understanding of the concepts. To address this problem, this paper describes a mechanical power grid simulator, MechGrid, and the development...
The power system is a typical complex and nonlinear system in nature. Theoretically, the nonlinear approach can describe a dynamic system more accurately than a linear approach, but to an actual power grid, a linear approach was usually used to model a nonlinear problem approximately. To investigate when the system can be linearized and “how small is small” to linearize the system accurately, this...
