Assessment of retail and wholesale market competition in the Illinois electric industry /

In this report, the Commission examines developments relevant to the competitiveness of the retail and wholesale markets. In the retail market, two key indicators of activity are examined: The first indicator is the rate of customer switching from bundled services to "delivery services." Customers taking delivery services are either purchasing power and energy from ARES or are purchasing power and energy from the host utility on an "unbundled" basis under the utility's delivery services tariffs. Currently, bundled power sales mainly consist of sales to customers under the Sec. 16-110 "Power Purchase Option" (PPO). The second indicator of retail activity presented in this report is the number of suppliers active in the State's nine service territories.

Privatização, desestruturação organizacional e da força de trabalho: o caso de uma empresa de energia

Este trabalho tem como objetivo caracterizar o processo de privatização, como parte do projeto da reestruturação produtiva e de reforma do Estado, no contexto da crise do setor energético brasileiro nos anos 90. Para isto, é tomado, como caso exemplar, uma empresa do setor elétrico, para investigação das implicações ocorridas para a organização e para os seus trabalhadores. Entende-se aqui que a reforma do setor elétrico é parte integrante de mudanças mais amplas, remetidas à reforma do Estado, a qual adotou como ideologia as políticas neoliberais a partir dos anos 1990 no Brasil. É neste contexto que entendemos a privatização das empresas de utilidade pública no Programa Nacional de Desestatização (PND). Tomamos para o estudo de caso uma empresa do setor elétrico, tendo em vista que a energia representa um insumo essencial para o desenvolvimento de um país. Foi a partir também do desenvolvimento das formas de energia que ocorreram as revoluções industriais e, com isso, o desenvolvimento do capitalismo industrial. Além de revisão teórica e bibliográfica, o estudo contou com pesquisa documental dos relatórios anuais, do planejamento estratégico e da pesquisa de clima organizacional realizados pela empresa investigada. Contribuiu, para a análise, ainda, o processo de observação da autora como participante do cotidiano organizacional, na medida em que é trabalhadora e assistente social da empresa. A pesquisa revela que o período de sete anos em que a empresa permaneceu incluída no PND, acarretou a sua des/reestruturação tanto para a identidade empresarial da empresa quanto para os seus recursos humanos. Diante, da reestruturação, a empresa elaborou seu Planejamento Estratégico, buscando, segundo os padrões empresariais vigentes, ser referência mundial, ter excelência empresarial e rentabilidade. Ao mesmo tempo, estabeleceu abstratamente a valorização das pessoas, a transparência, a ética e a responsabilidade sócio-ambiental. Porém, ao analisar o seu Planejamento Estratégico e a pesquisa de Clima Organizacional, constatamos as contradições existentes na empresa. Entre as contradições, verificamos ser a gestão de recursos humanos, o principal desafio a ser superado nesse processo de reestruturação.

Application of neural network to hybrid systems with binary inputs

Boolean input systems are in common used in the electric industry. Power supplies include such systems and the power converter represents these. For instance, in power electronics, the control variable are the switching ON and OFF of components as thyristors or transistors. The purpose of this paper is to use neural network (NN) to control continuous systems with Boolean inputs. This method is based on classification of system variations associated with input configurations. The classical supervised backpropagation algorithm is used to train the networks. The training of the artificial neural network and the control of Boolean input systems are presented. The design procedure of control systems is implemented on a nonlinear system. We apply those results to control an electrical system composed of an induction machine and its power converter.

Control strategy for Boolean input systems

The purpose of this paper is to design a control law for continuous systems with Boolean inputs allowing the output to track a desired trajectory. Such systems are controlled by items of commutation. This type of systems, with Boolean inputs, has found increasing use in the electric industry. Power supplies include such systems and a power converter represents one of theses systems. For instance, in power electronics the control variable is the switching OFF and ON of components such as thyristors or transistors. In this paper, a method is proposed for the designing of a control law in state space for such systems. This approach is implemented in simulation for the control of an electronic circuit.

Network reconfiguration and loss allocation for distribution systems with distributed generation

Distribution systems with distributed generation require new analysis methods since networks are not longer passive. Two of the main problems in this new scenario are the network reconfiguration and the loss allocation. This work presents a distribution systems graphic simulator, developed with reconfiguration functions and a special focus on loss allocation, both considering the presence of distributed generation. This simulator uses a fast and robust power flow algorithm based on the current summation backward-forward technique. Reconfiguration problem is solved through a heuristic methodology and the losses allocation function, based on the Zbus method, is presented as an attached result for each obtained configuration. Results are presented and discussed, remarking the easiness of analysis through the graphic simulator as an excellent tool for planning and operation engineers, and very useful for training. © 2004 IEEE.

Reliability evaluation of distribution systems considering automatic reclosers

This paper presents a new methodology to evaluate in a predictive way the reliability of distribution systems, considering the impact of automatic recloser switches. The developed algorithm is based on state enumeration techniques with Markovian models and on the minimal cut set theory. Some computational aspects related with the implementation of the proposed algorithm in typical distribution networks are also discussed. The description of the proposed approach is carried out using a sample test system. The results obtained with a typical configuration of a Brazilian system (EDP Bandeirante Energia S.A.) are presented and discussed.
