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 proposes a web-based architecture to enable information retrieval and appliance management for a Home Energy Management (HEM) system. With the proposed architecture, homeowners can monitor their basic energy usage information, and can perform necessary appliance management based on their pre-defined load priority, preferences, and comfort settings. The proposed architecture is designed...
Design of an effective home energy management (HEM) system requires selection of an appropriate communication technology. The objective of this paper is to compare commonly used communication technologies for HEM implementation in a premises area network, in terms of their latency, throughput, reliability, power consumption and implementation costs. Communication technologies of interest include ZigBee,...
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...
Upgrade of electric distribution networks is vital for unified modernization of the grid. To fulfill this prerequisite and contribute to the overall development of the smart grid, the U.S. government awarded up to 50% federal grants to 57 Electric Distribution Systems (EDS) projects in the Smart Grid Investment Grant (SGIG) program under the 2009 American Recovery and Reinvestment Act (ARRA). This...
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...
A Home Energy Management (HEM) system plays a crucial role in realizing residential Demand Response (DR) programs in the smart grid environment. It provides a homeowner the ability to automatically perform smart load controls based on utility signals, customer's preference and load priority. This paper presents the hardware demonstration of the proposed HEM system for managing end-use appliances....
Demand response (DR) is an important demand-side resource that allows for lower electricity consumption when the system is under stress. This paper presents a DR framework that can be implemented within a home area network, as well as a conceptual hardware architecture for a Home Management System (HMS) and appliance interface units that enable in-home DR implementation. The proposed DR strategy allows...
The critical fault clearing time is an indicator of transient stability margin and it changes with the generator load condition. If the protection devices are capable of operating before the critical clearing time (CCT) and also providing faster auto-reclosing as soon as the fault is cleared, then the system will not loose its synchronism and remain in stable operation. The goal of this paper is to...
