Decentralized multi-agent algorithm for voltage control

In recent years, due to liberalization, power systems are being operated closer and closer to their limits. At the same time, they have increased in size and complexity. Both factors increase the risk of major power outages and blackouts. Most of the existing emergency control ideologies use two approaches: control in case of accidental disturbance and control in case of a parameter deviation. In the existing control ideology there is a lack of procedures that would provide a smooth transition from operational to the effective emergency control, as well as a lack of algorithms that would increase the fault tolerance and adaptability of the local control. This article describes the development and testing a decentralized multi-agent algorithm for voltage stability control which aims to reduce the existing shortcomings.
