Control of reactive power and voltage in emergencies Conference Paper uri icon


  • A method is introduced which assures quite feasible computation of control actions to be taken to remedy voltage problems resulting in a section of a system because of a disturbance. The process is devised so as to conform to the natural structural features of the problem. A monitoring process is proposed. If a viability crisis is detected, first a cluster of interacting control tools are selected to match the cluster of violations. Then an effective viabilizing algorithm is carried out to restore viable voltage values in a manner least disruptive to the system. The algorithm only covers the affected cluster. Consequently it is of small dimension and converges fast. Use of this approach should substantially improve both cut and try approach by the operator on line, and straightforward computationally demanding computer implementations such as optimal load flow.
