Voltage Collapse Avoidance in Power Systems: A Receding Horizon Approach

Abstract

ABSTRACT-In this paper, a receding horizon control approach is developed for voltage stabilization in power systems. The primary focus is on a benchmark system proposed in the context of a European project. The system is termed hybrid due to the finite set of control inputs, state automata description of the voltage primary controller and their interactions with the load nonlinear continuous dynamics. Moreover, the network topology imposes hard constraints on the states. All these make the control problem quite challenging. For different realistic scenarios, the proposed control algorithm is shown to stabilize the bus voltages at acceptable levels. The computational demand fits the real time allowed slot, making the scheme attractive for large scale applications as an area central controller.

A Hybrid System Approach to the Analysis and Design of Power Grid Dynamic Performance

“…In [31]- [33] the authors have attacked problems on voltage stability and control in power grids in terms of mixed logical dynamical systems and model predictive control. Also the approach based on model predictive control is reported in [34], [35]. In [36] the authors apply the hybrid input/output automaton to analysis of a power transmission system with relay control.…”

Hybrid controller for safe microgrid operation

“…In [11][12][13] the authors have attacked problems of voltage stability and control in power grids in terms of mixed logical dynamical systems and model predictive control. Also the approach based on model predictive control is reported in [14,15]. In [16,17] the authors study on-ship power system management using a hybrid system model, which system is close to the microgrid architecture.…”

Some Reflections on Model Predictive Control of Transmission Voltages

“…now this control technique has not received more attention from power system researchers and practitioners, although II. BRIEFREVIEWOFMODALPREDICTIVEGONTROL recent references show a growing interest for this approach Standard MPC (also referred to as moving horizon or [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].receding horizon control) is essentially a class of computer Practical interest in using MPC is driven by the fact that control algorithms to control the future behaviour of a system industrial processes need to be operated under tighter through the use of an explicit model of the latter [4,5]. At each performance specifications and at the same time more and control step the MPC algorithm computes an open-loop more constraints (dictated by economical, environmental, and sequence of controls in order to optimize the future system safety considerations) need to be satisfied [2,3].…”
