Distributed underfrequency load shedding using a multi-agent system

Underfrequency load shedding (UFLS) is critical for mitigation of large disturbances on a power grid. There are centralized and distributed UFLS methods. In this paper, the proposed distributed methodology uses a multi-agent system (MAS). The framework and classification of agents are presented. Steps for monitoring, estimation, and distributed computation are developed, implemented, and tested in a testbed environment. A comparison has been performed to show that the performance and capability of load shedding can be enhanced by the multi-agent scheme.
