Centralized transmission expansion planning of old regimes needs be revised for its suitability in competitive electricity markets. This paper reviews centralized transmission expansion methodologies and its regulatory fundamentals. Using a classic centralized, cost minimization methodology, the paper shows the inconsistencies between centralized and competitive planning of electricity transmission. A proposal for transmission expansion planning is outlined; the proposal applies for electricity markets where a single entity is in charge of determining the transmission expansion plan and takes into account the competitive reactions of participants in the market.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

Glenbrook is located within the Norwalk-Stanford area of southwestern Connecticut. In the summer of 2000, a low voltage event occurred in the area. Voltage recovery took approximately 8 to 10 seconds. Transmission planning studies have confirmed that the Norwalk-Stamford area is susceptible to a possible voltage collapse during certain contingencies. To mitigate similar low voltage conditions, three possible solutions were investigated by NU; install fixed shunt capacitors, upgrade existing overhead lines to a higher voltage level, and install a FACTS device. Of the three alternatives investigated, NU concluded that a FACTS device was the only near term viable option. The function of the STATCOM and its location on the system are discussed. Reasons for the finally chosen configuration are give, the choice being made to maximize availability, even following a circuit breaker failure or bus fault. The overall design of the STATCOM and its layout are described, together with a description of the chain-link voltages sourced converter.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

They are obtained from the field measurements of individual consumers' load curves, and can be divided into two approaches. The first is based on the predefined consumers classes, the second uses pattern recognition methods to derive typical load profiles (TLP) from the obtained measurements. Since, it is clear that no single approach for classification is \"optimal\", multiple methods have to be used to verify the obtained results. For that purpose the hierarchic clustering algorithms and fuzzy c-means algorithm are applied. Results obtained demonstrate the ability of the used algorithms to classify different daily load curves and to generate comparable results. The most similar results of applied clustering algorithms were obtained by fuzzy c-means algorithm and hierarchical clustering algorithm with Ward distance between clusters.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

This area of engineering has been less attractive to the bright students, as it had the reputation of being an old, mature and unexciting area with limited opportunities for innovation. Employment opportunities in the electric power industry have also been limited. This situation appears to be rapidly changing. The restructuring of the electric power industry - a shift from the monopolistic to a competitive structure has introduced new financial and social pressures. The challenge for the industry is discussed. Both the industry and university participants stand to gain from a healthy and meaningful collaborative research partnership. In addition to leading to very good power engineering education programs, such partnerships could produce new technologies of immense value to the industrial partner. Many of the problems the power industry needs to solve today will require the application of several supporting technologies. Universities are in a better position to form a pool of experts in different disciplines and apply them for the solution of power system problems.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.

In many cases a large part of dispersed generation is not included in communication based control systems making it difficult to coordinate the operation of these generators. This paper introduces an automatic and autonomous control strategy for intelligent control of the excitation system of the dispersed generator. It uses an expert system technique to provide voltage support and voltage following modes of excitation control as necessary. The implication of the control strategy is that the dispersed generator can be used to support the network during power system perturbations but is operated as a voltage follower under normal conditions when the network is grid connected. The expert system also makes it possible for the dispersed generator to operate isolated from the grid following the sudden loss of the connection. Simulation studies are used to demonstrate the effectiveness of the expert system under a variety of abnormal operating conditions.","PeriodicalId":131986,"journal":{"name":"2003 IEEE Power Engineering Society General Meeting (IEEE Cat.
