Performance Based Ratemaking In Electric Distribution Services

Uguz, Mustafa 01 December 2006 (has links) (PDF)
Regulation is one of the main elements in electric distribution services. The objective of the regulation is to maintain the balance between the rates and the service quality of electric distribution on behalf of both utilities and customers. In rapidly changing world the regulation regimes are also changing .In this thesis, an increasingly implemented regulation model in electric distribution, performance based ratemaking is studied. Its advantages and disadvantages, implementing methods and its quality effects are analyzed.

[en] APPLYING RISK CLASSIFICATION METHOD IN CAR INSURANCE MARKET / [pt] MÉTODO DE CLASSIFICAÇÃO DE RISCO APLICADO AO MERCADO DE SEGUROS DE AUTOMÓVEIS

WILSON LINS MORGADO 14 February 2005 (has links)
[pt] A estimação do risco em seguros de automóveis representa um difícil problema de regressão. As dificuldades vão desde a utilização de um grande número de variáveis discretas como explicativas, até a distribuição particular dos ruídos e uma quantidade expressiva de categorias com valores nulos e valores discrepantes. Supondo que os problemas de estimação estejam relacionados com a classificação do risco adotada pelo mercado, este trabalho propõe um método de classificação alternativo. O método desenvolvido foi baseado na técnica de análise fatorial, e no algoritmo de agrupamento de dados denominado fuzzy clustering system. Para avaliar a eficiência do método em solucionar os problemas de estimação, optou-se por utilizar o erro resultante da aplicação de modelos lineares generalizados. Ao final, o erro de estimação obtido diante da classificação proposta, foi comparado ao obtido diante da classificação usual de mercado. / [en] The estimation of car insurance risk rate represents a difficult regression problem. One of the difficulties of this problem is the use of a number of discrete independent variables and a specific error distribution that presents an expressive number of null and outlier values. Assuming that these estimation problems are related to the risk classification adopted by the insurance companies, this work proposes an alternative classification method. This method is based on factorial analysis techniques and on the algorithm known as Fuzzy Clustering System. To evaluate the efficiency of this method in solving the problems identified, the risk was estimated using generalized linear models. The errors from each model were obtained and compared between classifications.
