    This paper sets out the economic foundations that underlie competitive markets in electricity generation. It moves from a general formulation of a competitive market to discuss traditional models of optimal electricity pricing. It shows how an auction market can produce the same results and discusses the option of bilateral trading. Models of market power, which can lead to higher process and redu... View full abstract»

    Reliability is an important issue in power systems and historically has been assessed using deterministic criteria and indexes. However, these approaches can be, and in many cases have been, replaced by probabilistic methods that are able to respond to the actual stochastic factors that influence the reliability of the system. In the days of global, completely integrated and/or nationalized electr... View full abstract»

    Three very different methods of accomplishing the same task-managing the operation of the transmission system in the deregulated power system operating environment-have been implemented as deregulated market structures have been created around the world. They are first, the optimal power flow (OPF) model found in various implementations in the United Kingdom, parts of the United States, and in Aus... View full abstract»

    The electric utility industry is undergoing unprecedented changes in its structure worldwide. With the advent of an open market environment and competition in the industry, and restructuring of the industry into separate generation, transmission, and distribution entities, new issues in power system operation and planning are inevitable. One of the major consequences of this new electric utility e... View full abstract»

    A power system may be subject to (rotor) angle, frequency or voltage instability. Voltage instability takes on the form of a dramatic drop of transmission system voltages, which may lead to system disruption. During the past two decades it has become a major threat for the operation of many systems and, in the prevailing open access environment, it is a factor leading to limit power transfer. The ...

    The business protocols and rules of the competitive electricity market are resulting in fragmentation of the historical vertically integrated structures. Electric services are offered at either cost or market-based prices depending on their type and the level of competition in a particular product. System stabilizing measures are essential for maintaining system security, yet their value is either... View full abstract»

    Cited by:  Papers (40)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (285 KB)

    The fast development of power electronics based on new and powerful semiconductor devices has led to innovative technologies, such as high voltage DC transmission (HVDC) and flexible AC transmission system (FACTS), which can be applied in transmission and distribution systems. The technical and economical benefits of these technologies represent an alternative to the application in AC systems. Der... View full abstract»

    Utility deregulation will have tangible and intangible effects on power quality requiring industry-wide action to maintain adequate standards. These effects are discussed in the first part of the paper. The increasing trend towards more extensive use of power electronic control at the generation, transmission and utilization systems following deregulation has power quality implications that will a...

    This paper discusses the state of the art in electric power system state estimation. Within energy management systems, state estimation is a key function for building a network real-time model. A real-time model is a quasi-static mathematical representation of the current conditions in an interconnected power network. This model is extracted at intervals from snapshots of real-time measurements (b... View full abstract»

    The author reviews and comments upon George Morton's predictive paper "Machines with Imagination". He argues that Morton's paper demonstrates a significant insight into the progress of machine intelligence, particularly because that progress was hardly accomplished in a linear progression of systematic advances. Indeed, the forecasts laid down in Morton's paper have become pertinent only after a s... View full abstract»

    Despite the early identification of Edison with space flight in science fiction, journalists and the public tend to view events such as the moon landing as the triumphs of mechanical and aeronautical engineers and "rocket scientists". IEEE members know that the picture is more complex, and that the developments in flight and, more particularly, space travel in this century would not have been poss... View full abstract»
