8. OTIMIZAÇÃO DE PORTFÓLIO DE CONTRATOS DE ENERGIA EM SISTEMAS HIDROTÉRMICOS COM DESPACHO CENTRALIZADO / PORTFOLIO OPTIMIZATION OF ENERGY CONTRACTS IN HYDROTHERMAL SYSTEMS WITH CENTRAL DISPATCH
Portfolio optimization has been widely used to select investments in the financial area. The first proposal in this topic was the Markowitz mean-variance approach, which uses, respectively, the mean and the variance as measures of portfolio return and risk. Since Markowitz many other approaches, which adopt alternative risk measures, have been proposed, e.g.

9. SPOT PRICE REGULATION, INVESTMENT ATTRACTION AND RISK MANAGEMENT IN THE BRAZILIAN ELECTRICAL ENERGY MARKET / FORMAÇÃO DO PREÇO, ATRAÇÃO DE INVESTIMENTOS E GERENCIAMENTO DE RISCO NO MERCADO BRASILEIRO DE ENERGIA ELÉTRICA
O mercado brasileiro de energia elétrica ainda não encontrou um modelo de mercado e de formação de preço que garanta a expansão auto-sustentada da oferta. Investigando em detalhe o modelo atual de despacho da geração e formação do preço, demonstramos a sua pouca eficácia na atração de investimentos, e identificamos a causa dessa falha como send
