The proliferation of distributed energy resources is setting the stage for modern distribution systems to operate as microgrids, which can avoid power disruptions and serve as resources for fast recovery during macrogrid disturbances. Microgrids are, therefore, major assets to improve the grid resilience. However, the offered resilience is seriously undermined if microgrids are not properly protected...
To assess the effectiveness of integrating distributed energy resources, we investigate three types of grid systems: power grid with only bulk energy generators, power grid with distributed energy resources, and power grid with both distributed energy resources and storage devices. Based on the metrics of power cumulative cost and user service reliability, we analyze the impact of integrating distributed...
This paper presents a conceptual architecture for Micro Grid. The approach utilizes the strategy of control and coordination from Role Autonomous Decentralized System (RoADS) for autonomous operation of a Micro Grid. This architecture aims to optimize the generation production of local distributed generators. Case studies have been performed on a typical low voltage feeder with several distributed...
Ultimately, Advanced Metering Infrastructures, Distribution Automation, Substation Automation, Distribution Management Systems, Outage Management and Mobile Workforce Management Systems, GIS Facilities Modeling and Management, Asset Management Systems, Customer Systems and others must all fit this Smart Grid framework to be effective. They must act together to leverage the potential of a Smart Grid...
There has been much recent discussion on what distribution systems can and should look like in the future. Terms related to this discussion include smart grid, distribution system of the future, and others. Functionally, a smart grid should be able to provide new abilities such as self-healing, high reliability, energy management, and real-time pricing. From a design perspective, a smart grid will...
The following topics are dealt with: system wide events; energy resources; new technologies; power reliability; quality and safety; measurement and control; market structures; wind power; nuclear power; distributed generation; smart grid; vision for 2020.
In this paper, the authors deal with the issue of power quality phenomena in the distribution system that affects the reliability of the power supply to sensitive loads. Traditional solutions to power quality problems have been discussed here and the use of a microgrid as a preferred solution is presented. When the conventional and non-conventional micro sources are combined with energy storage devices,...
