Bulk electric system reliability analysis is an important activity in both vertically integrated and unbundled electric power utilities. Competition and uncertainty in the new deregulated electric utility industry are serious concerns. New planning criteria with broader engineering consideration of transmission access and consistent risk assessment must be explicitly addressed. Modern developme...

In the smart grid, large consumers can procure electricity energy from various power sources to meet their load demands. To maximize its profit, each large consumer needs to decide their energy procurement strategy under risks such as price fluctuations from the spot market and power quality issues. In this paper, an electric energy procurement decision-making model is studied for large consume...

The U.S. acid rain program, Title IV of the 1990 Clean Air Act Amendments, is a pioneering experience in environmental regulation by setting a market for electric utility emissions of sulfur dioxide (SO2) and by including a voluntary compliance provision. Under the Substitution provision, non-affected electric utility units can voluntarily become subject to all compliance requirements of affect...

In this paper we present the application of techniques for Correlation Dimension Estimation to estimate the model order of electrical load data. Based on a correct model order, appropriately structured neural nets for load forecasting were designed. Satisfactory results were obtained in one-hour-ahead electrical load prediction on a six months benchmark from an electric utility in the USA.

The electric power generation business is facing uncertain and competitive environments with much financial risk. In this paper, we design and analyze a real options model for a utility with multiple inter-related generation planning projects. Also, comparisons relative to other models are made and a numerical example is provided so as to illustrate the optimal sequential decision making.

We discuss middleware requirements for remote monitoring and control applications. These requirements reflect our experiences with the RBMO Project (remote building monitoring and operations) of commercial buildings HVAC systems (heating, ventilating, and air conditioning) and our participation in standards efforts related to control of large electric utility grids. Similar requirements exist f...

1 The fundamental goal of an electric utility is to serve its customers with a reliable and low cost power supply. This goal has led to a number of standard protection engineering practices that ensure adequate service; however, with deregulation of the utility industry and increased competitive pressures, there is a desire to further improve service reliability and reduce costs. In this vein, ...

Managing electrical energy supply is a complex task. The most important part of electric utility resource planning is forecasting of the future load demand in the regional or national service area. This is usually achieved by constructing models on relative information, such as climate and previous load demand data. In this paper, a genetic programming approach is proposed to forecast long term...

Keep things simple when controlling bidirectional pulsewidth modulation rectifiers by considering the utility grid as a virtual electric machine. The advantage is that the air-gap flux of this big machine can be directly measured in a straightforward way. Therefore, as shown in this paper, principles of field orientation can be applied to control the power flow, yielding high-dynamic performance.
