Islanding operation of active distribution grids using an agent-based architecture

Abstract

This paper presents a decentralized architecture for the islanding operation of distribution grids with large volume of distributed generation. This architecture involves the definition of network blocks which share the responsibility of frequency control. The control block abstraction was particularly designed to support the transition from regular grids to smart grids. In addition, the control schemes were developed using an agentbased paradigm. Hence, an agent-based simulation platform was implemented using libraries from the Java Agent Development Framework (JADE). The control schemes were evaluated using a test system with different sorts of distributed energy resources and modeled in the EUROSTAG environment. Simulation results show the effectiveness of the control architecture when different failure events are applied to the test system.

A Review of Architectures and Concepts for Intelligence in Future Electric Energy Systems

“…The fault prevention and self-healing techniques for smart grids based on MAS are also widely discussed. One technique presented in [109] is based on calculation of optimal network configuration achieved by opening or closing the switching elements to isolate the fault. Another similar technique considers partitioning the grid into multiple islands that disconnect from the main grid in case of a failure.…”

“…Another similar technique considers partitioning the grid into multiple islands that disconnect from the main grid in case of a failure. The agents responsible for those islands cooperatively prepare plans of action to isolate the faulty parts from the power grid [109].…”

A Review of Agent and Service-Oriented Concepts Applied to Intelligent Energy Systems

“…This cluster can also provide power balancing as an additional service to the main power grid. The micro grid is coupled with the main grid through a single point and thus can be easily disconnected in order to work autonomously in islanded mode [21], [44]- [46]. This feature is useful when a critical fault is threatening the main grid-the micro grid can quickly disconnect from the main grid to avoid being impacted by the failure and to contribute to further spreading of the fault.…”

Agent-Based System Applied to Smart Distribution Grid Operation

“…The percepts node voltage, switch status, neigh-power flow,a n dFPI stand for In order to pursue all goals, each block agent is responsible for feeding and sharing information with its neighboring agents through the electric utility communication system. Hence, actions related to searching for clients and neighbors as well as the information flow rules are designed as presented in (Issicaba et al, 2010). Other actions, such as send Q setpoint and send tap setpoint are applied when inadequate node voltages are perceived.…”
