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...
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...
A confluence of industry drivers including increased deployment of renewable generation, cost for managing grid peak demands, and capital investments in grid infrastructure for reliability and smart grid initiatives are creating a new interest in electric energy storage systems. This paper will review the role and value of energy storage systems to the electric grid. It will present findings from...
Smart Grid is aimed to incorporate monitoring, analysis, control and communication capabilities to improve reliability and energy efficiency. However, currently there is no enough sensor to provide information interface for the implementation of smart grid. Therefore, new types of sensors should be deployed to assist the implementation of smart grid. This paper proposes a novel scheme, in which new...
Various voltage and current sensing solutions including optical sensors, air-core coil based sensors, resistive-capacitive dividers, and hybrid solutions have gained increasing interest for use in the digital power grid. These sensors offer many attractive features including safe design, high accuracy and linearity, wide bandwidth, smaller size, and potentially low cost. Here, we will explore several...
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...
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...
Calculating the reliability of the power grid is difficult because it is made up of thousands of components and even though the failure mode of each component may be known, they are not independent of each other. Thus the models required to conduct reliability analysis are difficult to develop and are often complex enough to make the techniques for analysis very cumbersome. Usually controllers like...
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...
This paper presents the result of quantitatively evaluating the energy saving effect by the combination of pHV and SOFC as parameters of the usage pattern of pHV and the demand characteristic of a house. First, we modeled energy system models of the house, and derived the optimal operation of pHV and SOFC by the analysis. Then, we compared the analysis result of various driving patterns, driving distances,...
This paper describes research in progress for a panel session presentation on how phasor measurement unit (PMU) values can be used to improve power system operations beyond their use in state estimation.
This paper discusses a study funded the California Energy Commission (CEC), performed by New Power Technologies with Southern California Edison to validate a system-wide, distribution element-level (high definition) power system simulation using field measurements. Comparisons of system simulation results and field measurements showed that the simulation is a statistically significant predictor of...
Demand response (DR), coupled with smart-grid technologies, will be a big initiative for energy companies in the US for the next 3-5 years. This paper summarizes the key technical and IT challenges that will need to be solved to properly deploy DR at the wholesale and retail levels.
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...
Smart grid technologies for the high voltage power grid usually refer to (1) the new sensors that can sample voltages and currents at very fast rates and calculate their phase relationships by coordinating with aGPS time signal, (2) the high bandwidth communications that can move this voluminous measurement data to monitoring and control stations, and (3) fast controllers like breakers and power electronic...
This paper will discuss the purpose and value of energy storage as a transitional technology towards SmartGrids, as well as its utilization within the future network operational arrangements.
