Due to the energy challenges in the world, new types of generation technologies, such as renewable energy based generators, attract great attention and are being quickly developed, which results in the dramatic developments and changes in modern power systems, the communication technologies play a increasingly important role in guaranteeing the power system's stability, reliability, and security....
The complex system architecture required to support smart grid technology introduces an undetermined level of risk in power systems. Many current techniques to evaluate cyber specific risk fail to scale to such a large environment. While attack graphs and trees are frequently used to model system security, both approaches require the ability to predict potential attack vectors. Access graphs have...
The Multi-Area Thévenin Equivalent algorithm (MATE) partitions a network into a number of subnetworks connected by links. The solution proceeds in two stages: first the subnetworks are solved independently, with the links open, and then the system formed by the links is solved with the subnetworks represented by their Thévenin equivalents as seen from the link nodes. In this paper, an overview of...
This paper represents a modified dynamic programming solution to the unit commitment (UC) problem. The UC is a complex decision-making process because of multiple constraints which may not be violated while finding the optimal or suboptimal commitment schedule. There are many methods to solve the UC problem gradually. So, before we present our method, we will show the drawbacks of the standard dynamic...
This paper proposes an information fusion method for diagnosis. Multilayer structure of information fusion included data proposing, feature extraction and decision making, is constructed for dealing with the objects such as current, voltage and wave, etc. A Petri-network and a fault matching method of WAMS data are used in characteristic fusion. The application of this fame in the simulation resolves...
This paper describes the Intelligent Energy Management (IEM) System of the Future Renewable Electric Energy Delivery and Management (FREEDM) System. The IEM system is comprised of three main subsystems: the solid state transformer (SST), the reliable and secure communication (RSC) network, and distributed grid intelligence (DGI). Each of the subsystems is briefly described and the primary challenges...
For building self-healing, interactive and collaborative intelligent distribution network and meeting the needs on energy management of intelligent distribution network with high penetration of Distribution Generations (DGs), smart integration has become very important. Multi-agent System and Service-oriented architecture (MAS-SOA) will provide new ways and means for the establishment of the distributed,...
