The large-scale intermittent wind has been incorporated into current grid. in order to achieve transient angle stability quantitative analysis and evaluation, this paper proposes a fast assessment method of wind power generators and coal-fire power generators in transient angle stability control. Using the EEAC (extended equal area criterion) angle stability quantification theory, the defense vectors...
Due to the high risk of cascading failures, an online solution for N-2 failure control becomes increasingly important. Dual short-circuit fault, as one of the simplest N-2 failure, was studied in this article. Some explorations were made aiming at the composition rules of critical cluster (CC) and the relationship between the dual short-circuit fault's conservative control quantity and the individual...
The potential of offshore wind energy has been commonly recognized and explored globally. Many countries have implemented and planned offshore wind farms to meet their increasing electricity demands and public environmental appeals, especially in Europe. With relatively less space limitation, an offshore wind farm could have a capacity rating to hundreds of MWs or even GWs that is large enough to...
This paper addresses the state-variable stabilizing control of the power system using such series FACTS devices as TCPAR installed in the tie-line connecting control areas in an interconnected power system. This stabilizing control is activated in the transient state and is supplementary with respect to the main steady-state control designed for power flow regulation. Stabilizing control laws, proposed...
