Risk assessment of catastrophic failures in electric power systems
The declining reliability of the US electric power system is raising major concerns among both politicians and power engineers in the USA. One of the reasons put forward by the North Electric Reliability Council (NERC) is the detrimental role played by the protection systems during large disturbances, which tend to help the perturbations to propagate through over-tripping of fault free system ...

Repair strategies for minimising the risk of cascading failures in electricity networks
In this work, we develop repair strategies for simplified models of electric power grids. The goal is to gain insight into the combinatorial properties of repair problems in order to improve maintenance and restoration planning. Firstly, we consider a seriously damaged grid and try to find the set of lines that should be repaired first in order to resupply the customers as fast as possible. We ...

Controlling cascading failures with cooperative autonomous agents
Cascading failures in electricity networks often result in large blackouts with severe social consequences. A cascading failure typically begins with one or more equipment outages that cause operating constraint violations. When violations persist in a network, they can trigger additional outages which in turn may cause further violations. This paper proposes a method for limiting the social ...

Reciprocally altruistic agents for the mitigation of cascading failures in power grids
Cascading failures in electrical power networks often come with disastrous consequences. A variety of schemes for mitigating cascading failures exist, but the vast majority depend upon centralised control architectures. Centralised designs are frequently more susceptible to communications latency and bandwidth limitations and can be vulnerable to random failures and directed attacks. This paper ...
