This paper mainly study on the coordinated voltage control scheme with model predictive control (MPC). As the decomposition-coordination technology and the auxiliary problem principle is employed into the MPC based voltage control problem, a distributed voltage control model and structure can be obtained, and the global centralized optimization problem is decomposed into some sub-problems. All sub-problems...
Dynamic voltage stability analysis is mainly based on the time-domain solution of power system differential and algebraic equations. The modeling of each power element has a great influence on the correctness and complexity of stability analyzing. It is significant to model appropriately for simplifying calculation and drawing out principal contradiction. In this paper, the dynamical mechanism of...
This paper mainly study on the model predictive control (MPC) based method in the emergency voltage control. The coordinated voltage control scheme and the MPC model of voltage control are introduced firstly. Next, the Lagrange decomposition and auxiliary problem principle is employed into the MPC model of voltage control and a distributed MPC based voltage control scheme can be obtained, by which...

Voltage stability is one of the aspects of the power system stability. Since regulating transformers are more and more used in modern power system, tap change has often been considered as a principal mechanism that may lead to voltage collapse, but tap change can also rescue a would-be collapse system by extending the power transfer limit. Using time domain medium-and-long term voltage stability simulation...
