This paper proposes an optimization based method of planning reactive power control for electric transmission systems to endow them with the capability of being reconfigured to a secure configuration under a list of contingencies. The overall objective function is to minimize the installation cost of new controls such as mechanically switched capacitors, while satisfying the requirements of voltage...
This paper proposes an optimization-based method of planning reactive power control for electric transmission systems to endow them with the capability of being reconfigured to a secure configuration under a list of contingencies. The overall objective function is to minimize the installation cost of new controls such as mechanically switched capacitors, while satisfying the requirements of voltage...
Voltage instability can be mitigated or avoided by coordination of appropriate control resources. In addition, to meet the power quality requirements, it is desirable to find the whole minimal-cost trajectory using available controls without violating any constraints. This is the trajectory optimization problem and intrinsically hard to solve in power systems because of the interactions between continuous...
This paper introduces a method for determining optimal location and capacity of dynamic shunt reactive power (VAR) support which is needed to enhance power quality and ensure short term stability with respect to credible contingencies. In this paper, simulated annealing (SA) and trajectory optimization (TO) technique is proposed for solving mixed integer minimax trajectory optimization (MIMTO) problem...
This paper proposes a new optimization based algorithm to plan the minimum amount of switched shunt and series capacitors to restore the voltage stability of a power system after severe contingencies. Through parameterization of severe contingencies, the continuation method is applied to find the critical point. Then, the backward/forward search algorithm with linear complexity is used to select candidate...
