Autonomic control algorithm selection in decentralised power systems: A voltage control case study

As power systems evolve into “Smart Grids” and beyond, they will increasingly rely on numerous sophisticated control algorithms to meet the demands of users and optimise operation. However, it is unlikely that a single algorithm can deliver the best performance for all possible network configurations, conditions and performance objectives. By judiciously selecting different algorithms better overall performance can be achieved. This paper describes an approach to selecting control algorithms for power systems; including a case study demonstrating both the need for and the effectiveness of algorithm selection for a voltage control problem on an 11 kV network.
