President Obama called for doubling the share of renewable energy in the nation's supply in three years. California has a renewable energy target of 33% percent by 2030. These bold commitments need transformational strategies to achieve them. Government policies to achieve the ultimate goal of carbon reduction in electric energy systems are to (i) increase renewable penetration, and to (ii) introduce...
Cyber security of Supervisory Control And Data Acquisition (SCADA) systems has become very important. SCADA systems are vital for operation and control of critical infrastructures, such as the electrical power system. Therefore, a number of standards and guidelines have been developed to support electric power utilities in their Cyber security efforts. This paper compares different SCADA Cyber security...
Synchrophasor technology was first introduced in 1980s. Since then, many electric utilities such as American Electric Power (AEP), Bonneville Power Administration (BPA), Southern California Edison (SCE), New York Power Authority (NYPA), as well as universities such as Virginia Polytechnic Institute (VPI), have been conducting R&D to explore and advance the application of synchrophasor technology...
Pioneering efforts in showing how electricity energy storage can be a valuable asset in a Smart Grid Distribution System have been in process for the last few years. Several demonstration projects were completed to show how substation loading could be controlled and managed to delay upgrades. The next step was to show how the load deferral benefit could be combined with distribution circuit automation...
In April 2007 the GridWise® Architecture Council published the “Introduction to Interoperability and Decision-Maker's Interoperability Checklist Version 1.0” as a tool to be used by policy makers and executives making smart grid policy or investment decisions. Subsequently there has been a significant amount of additional work on smart grid interoperability by the council and others. This paper summarizes...
Jeju Island, which is the largest island in Korea, has an electric system which has special characteristics where a portion of the required electricity is being provided from the mainland through HVDC lines controlled by the frequency mode. Also, owing to its abundant wind resources, it is favorable for the installation of large scale wind farms with some already being operating and many under construction...
Asymmetric information in the electricity market creates incentive for customer aggregators (ESCOs, EMCOs, LSEs, etc.) to bid strategically as new information arrives. Such companies are pooling demand to provide enhanced services to customers. Since such demand pooling companies are not defined generically, all types of demand pooling companies will be termed demand serving company (DSC) to not confuse...
Distribution Systems traditionally have a tree-like structure with several branches. They supply loads that vary through the day and as a result, some branches are loaded more than others are. By reconfiguring the system, loads from the overloaded branches may be moved to under-loaded branches. Consequently, loads in the branches can be balanced so that the real power losses are reduced and the voltage...
Within the context of recent interest in `Smart Grids', this paper considers the possibility that domestic consumers could participate in demand side management. Price is one of the main concerns for domestic consumers, and hence Real Time Pricing (RTP) can have an influence on consumers with dispatchable generation such as micro combine heat and power (micro-CHP). These systems can reduce the annual...
This panel paper presents some outlines on the energy management of electric power microgrids with hybrid components. The hybrid nature of the microgrid is attributed to renewable energy sourced generation, energy storage, schedulable loads and information enabling technology such as smart meters. The panel paper and the accompanying presentation aim to describe the electric energy management visà-vis...
This paper will present experiences from the introduction of five new, three hour, interdisciplinary courses at the Missouri University of Science and Technology, USA at the undergraduate and graduate levels. The new courses introduced include: Adaptive Devices, Circuits and Systems; Adaptive Critic Designs; Computational Intelligence (CI); CI Methods in Electric Power; and Power System Simulation...
From the early days of Edison and Westinghouse, the educational institutions have played catch up with the developments in the electric energy industry. In those early years, the terms Electrical Engineering and Power Systems Engineering were used synonymously. Over the past two decades, the number of colleges and universities offering graduate degree programs in Electric Power Systems has dwindled,...
Illinois Institute of Technology (IIT) will lead an extensive and collaborative effort for establishing a World-Class Smart Grid Education and Workforce Training Center. The Center will develop and deploy smart grid technology courses and certificate programs via instructor-led and distance-learning methodologies. The Center will use the IIT's strong and already established smart grid and power engineering...
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...
Synchronized measurements became recently an affordable tool ready to be implemented not only at transmission system level but also at distribution level, mostly in conjunction with the applicability of the smart grid approach. As a preliminary step of introducing PMUs on a larger scale, extensive measurements campaigns, primarily dedicated to power quality purposes, were conducted within medium and...
This paper concerns the challenge of teaching future energy systems using concepts familiar to engineering students. It is stressed that unless operating and design problems are formulated in a way understandable to those who do not specialize in electric power systems it becomes very difficult to identify what may be the roadblocks to innovation and better performance of the evolving energy systems...
This paper presents the implementation of distributed energy resource management in smart grid operation. The approach utilizes the advantages of using multi agent systems for profitable operation of a smart grid in the energy market. The trading strategy adopted for the continuous double auction is a profit-maximizing adaptive bidding strategy based on risk and competitive equilibrium price prediction...
Conventional power systems have been experiencing transition from centralized supply side management to decentralized supply&demand side management due to power system restructuring and addition of distributed generations (DGs) and Smart Grids (SGs) or Smart Distribution Systems (SDSs) with renewable power sources in the past two decades. Therefore load management under the new operating environment...
A smart grid is capable of integrating a broad array of generation resources and enables the participation of demand side resources in reliable system operation. To cost effectively realize this flexibility, the associated devices and systems need to connect and interact simply and reliably. Interoperability is the important ingredient to make this happen. Because the electric system transcends organizational...
