Local controllers are essential in distribution networks; they are employed in classical devices such as load tap-changing (LTC) transformers and switchable shunt capacitors, and more recently in distributed generation (DG). The effective use of distribution management system (DMS) applications requires an accurate model of the interaction between the local controllers through the distribution system...
In this paper, an approach based on the concept of Model Predictive Control (MPC) is used to control transmission voltages and prevent long-term voltage instability. The MPC model is based on a linearized steady-state system model derived from power flow equations. Simulation results are presented for the case of Nordic32 test system.
In recent years, the analysis of voltage stability has become crucial for the proper operation of electrical power systems, especially when it comes to large systems. The need for effective voltage control strategies have been brought to evidence in a considerable number of studies, as power system loads are located farther away from power plants and losses have tended to increase due to heavier power...
