Multi-Agent System for Islanded Operation of Distribution Systems

The increasing penetration of local generators called distributed generators (DGs) has created a need for changing restoration schemes. Under islanded scenarios, a DG or a group of DGs can continue to supply a portion of the system that has been separated from the main utility system. However, the island may have a power imbalance and need load shedding in order to maintain it. This paper presents a decentralized restoration solution under such an islanded condition. This decentralized solution is a multi-agent system (MAS) with four types of agents. This MAS in development is responsible for load shedding after occurrence of an island and thereafter restoration of the shed loads if possible. The system is implemented in virtual test bed (VTB) and Java agent development framework (JADE) is used as an agent development toolkit
