Summary form only given. The paper presents that smart microgrid could offer a perfect power system with higher reliabilities which could guide customers to lower their costs and utilize electricity more efficiently. The task of improving the efficiency and upgrading the resiliency of the electric grid, in order to support clean and renewable energy, is one we cannot let be exported or delegated overseas...
The smart grid concept was introduced to the US utility industry by the Department of Energy (DOE). It was based on the visions of DOE's Grid 2030 and National Electric Delivery Technologies Roadmap. The debate over what constitutes a smart grid is still emerging. Nevertheless, we all agree that smart grid concept is complex and contains many interdisciplinary technologies and strategies. It is difficult...
Advances in technology and major programs to enhance the electric power system throughout the world have led to the concept of the “Smart Grid”. This concept has been formally defined in various places and is driving many of the current changes in educational curricula at all levels. This paper provides a brief summary of the known definitions and the resulting educational needs for the technical...
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...
In this paper we describe an effort which is under way at Carnegie Mellon University (CMU) in the Electric Energy Systems Group (EESG). We refer to this effort as the Dynamic Monitoring and Decision Systems (DYMONDS) initiative. Its objective is to develop an Information Technology (IT)-enabled framework in support of sustainable evolution of today's electric power systems into future energy systems...
Although a desirable attribute, not all operations models currently make use of real-time data for various reasons. To say the least, the regional scope and comprehensiveness that current data encompasses may be considered limited and incomplete. However, as computational, communication, security, and instrumentation technologies advance, smart grid technology demonstrates the potential to radically...
Security and economy are long standing underpinnings for power system operation. The evolution from regulated utility operation to competitive markets operation led to more formalized treatment of economy and security concerns through the deployment of market clearing applications that are based mathematical programming methods. Among the most common market clearing applications are security-constrained...
The electrical power grid is evolving into the “smart grid.” The goal of the smart grid is to improve efficiency and availability of power by adding more monitoring and control capabilities. These new technologies and mechanisms are certain to introduce vulnerabilities into the power grid. In this paper we provide an overview of the cyber security state of the electrical power grid. We highlight some...
