Deregulated electricity markets in the U.S. currently minimize total bid costs to select bids and their generation levels but determine payments based on market clearing prices. The inconsistency between auction and settlement mechanisms can lead to a significantly higher consumer payment. This gives rise to the “payment cost minimization,” an alternative auction mechanism that minimizes consumer...
The application of simple fuzzy power systems stabilizers (SFPSSs) to enhance the damping of inter-area oscillations of the Mexican Interconnected System (MIS) is presented. In particular, the work is focused on improving the damping of one of the most critical oscillation modes of the MIS: the north-south inter-area mode. The SFPSSs used in this work are characterized by a significantly reduced fuzzy...
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 paper proposes a multi-feature extraction algorithm aiming to recognize disturbances by analyzing synchrophasor data from wide-area monitoring systems. The novel algorithm utilizes wavelet transform (WT) to extract preliminary features from synchrophasors. Two types of features are created by organizing scaling coefficients and wavelet coefficients from WT. The multi-features are compressed by...
The integration of renewable energy sources such as wind power into power systems is quite difficult due to their stochastic nature. As wind power penetration begins to reach significant levels these difficulties can mean great financial expenses and increased carbon emissions. In this paper we demonstrate that through smart utilization of multiple generation sources, a technique we call integrated...
The quest for energy independence and the push towards sustainability coupled with the legislative initiatives and the recent advances in wind generation technology have made wind one of the fastest growing sources for electricity production. The effective integration of wind generation resources into the power grids requires the evaluation of the impacts of wind resources on the system performance...
This paper aims at identifying the options for designing an offshore electricity grid and the legal instruments to create such a grid. It will make a first attempt at presenting the technical and legal considerations which coastal states, EU and national legislators and policy makers should take into account in the coming years when planning and weighing their grid design options. By contrast to the...
As interest in renewable energy continues to gain momentum, use of power electronics in both generation and transmission systems has become increasingly important. One device that has enjoyed much interest as of late is the Battery Energy Storage System. Advancements in battery technology coupled with modern power electronics has resulted in a plethora of possibilities for such systems. This paper...
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...
Many technical areas in power systems require the simultaneous optimization of multiple and often conflicting objective functions with complicated non-linear constraints. The recent studies on multi-objective evolutionary computation methods have shown that the population-based stochastic algorithms are the most attractive approaches for this class of problems. Moreover, these methods can be efficiently...
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...
A methodology based on the security-constrained unit commitment (SCUC) is applied to analyze the transmission congestion in the Eastern Interconnection of the United States for 2008 and 2018. The proposed SCUC tool for this study is referred to as the POwer Market Simulator (POMS). The identified congestions are visualized along with the Geographical Information System (GIS) data and compared with...
This paper presents a useful and practical approach for assessing the impact of electric vehicles on the electric power distribution system while keeping to a manageable volume of detailed circuit and equipment studies. This paper addresses electric vehicles as an electric load only and does not consider the potential of the vehicle being a generation source. It also only addresses the substation,...
This paper presents how the two types of dynamic limits (dynamic interface limit and dynamic unit group limit) are implemented and enforced in a market clearing engine (MCE) based generation scheduling system, developed by AREVA T&D for North China Grid Company (NCG).
This paper describes the top-down value based transmission planning process for Eastern Wind Integration and Transmission Study (EWITS) with the consideration of large scale wind generation over the Eastern Interconnect footprint. Achieving 20% to 30% wind energy penetration across the Eastern Interconnect will require significant transmission infrastructure expansion. The transmission overlays developed...
Summary form only given. The paper will discuss the details and the mission of a DOE-funded wind energy consortium for the promotion of research, education, and workforce development.
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,...
Phasor measurement units (PMUs) were installed in an industrial distribution network and synchronized measurements taken from the PMU at medium and low voltage during different system states were analyzed. Two cases of system operation were investigated, normal and abnormal operation. Results from up to six PMUs were compared and analyzed for each case.
This paper describes a novel technique to eliminate the effect of decaying direct current (DC) component on DFT based phasor estimation. This technique is based on estimating the phasor of a sinusoidal wave corrupted by a DC component at an instant of time. Another phasor is estimated after half cycle from the instant of estimating the first one. The two phasors are added and a mathematical expression...
