In this paper, an agent-based distributed control scheme is presented to control single-phase parallel inverters in solar photovoltaic (PV) systems connected to microgrids. A communication assisted multi-agent framework is developed within microgrids where agents perform their tasks in a distributed manner with an aim of stabilizing load voltage and current under normal and faulted conditions through...
This paper presents a distributed multi-agent scheme for enhancing the cyber security of smart grids which integrates computational resources, physical processes, and communication capabilities. Smart grid infrastructures are vulnerable to various cyber attacks and noises whose influences are significant for reliable and secure operations. A distributed agent-based framework is developed to investigate...
This paper focuses mainly on the assessment of the transient stability of a smart power grid, including the effect of its generator load changing under different fault locations, using intelligent agent-based technology. To enhance a system's transient stability, its protection devices should operate before the critical clearing time (CCT) to avoid loss of synchronism. In this research, a multi-agent...
This paper presents the use of the multi-agent technology in order to enhance the transient stability of power systems by the dynamic evaluation of the critical clearing time (CCT) including the effect of the distance of fault locations and the impact of the renewable energy source (RES) integration. A multi-agent framework is developed in this research, where the intelligent agents use an algorithm...
In this paper, the voltage profile and power quality issues of a distribution network with distributed generator (DG) and series compensation are investigated. A doubly-fed induction generator (DFIG)-based DG unit and a series capacitor (SC) and a thyristor-controlled series capacitor (TCSC) are considered for the analysis. Series compensation is implemented to reduce voltage drops in the line and...
This paper presents the use of an intelligent multi-agent system (MAS) approach to investigate the effect of a sudden change in generator load and the impact of integrating renewable energy sources (RESs) on the enhancement of the transient stability of smart power grids. In this proposed approach, an algorithm is developed through which intelligent agents properly coordinate a system's protective...
This paper describes an intelligent agent approach to power system fault diagnosis during disturbance condition for the enhancement of the transient stability with better coordination of protection devices using auto-reclosing technique. The protection device agents can dynamically adapt the change in the system and thus they have the full flexibility to act accordingly. The modern electric power...
Flywheel energy storage (FES) has attracted new interest for uninterruptable power supply (UPS) applications in a facility microgrid. Due to technological advancements, the FES has become a promising alternative to traditional battery storage technologies. This paper aims at developing a tool to demonstrate the use of FES units for securing critical loads during a utility outage in a microgrid environment...
