Analysis of Electricity Market Prices Using Multidimensional Scaling

This paper studies the impact of the energy upon electricity markets using Multidimensional Scaling (MDS). Data from major energy and electricity markets is considered. Several maps produced by MDS are presented and discussed revealing that this method is useful for understanding the correlation between them. Furthermore, the results help electricity markets agents hedging against Market Clearing Price (MCP) volatility.

Multidimensional Scaling Analysis of Stock Market Indexes

This paper applies multidimensional scaling techniques and Fourier transform for visualizing possible time-varying correlations between 25 stock market values. The method is useful for observing clusters of stock markets with similar behavior.

Cournot model with investments to change the market size

We present a new deterministic dynamical model on the market size of Cournot competitions, based on Nash equilibria of R&D investment strategies to increase the size of the market of the firms at every period of the game. We compute the unique Nash equilibrium for the second subgame and the profit functions for both firms. Adding uncertainty to the R&D investment strategies, we get a new stochastic dynamical model and we analyse the importance of the uncertainty to reverse the initial advantage of one firm with respect to the other.

Multi-agent simulation of competitive electricity markets: Autonomous systems cooperation for European market modeling

The electricity market restructuring, and its worldwide evolution into regional and even continental scales, along with the increasing necessity for an adequate integration of renewable energy sources, is resulting in a rising complexity in power systems operation. Several power system simulators have been developed in recent years with the purpose of helping operators, regulators, and involved players to understand and deal with this complex and constantly changing environment. The main contribution of this paper is given by the integration of several electricity market and power system models, respecting to the reality of different countries. This integration is done through the development of an upper ontology which integrates the essential concepts necessary to interpret all the available information. The continuous development of Multi-Agent System for Competitive Electricity Markets platform provides the means for the exemplification of the usefulness of this ontology. A case study using the proposed multi-agent platform is presented, considering a scenario based on real data that simulates the European Electricity Market environment, and comparing its performance using different market mechanisms. The main goal is to demonstrate the advantages that the integration of various market models and simulation platforms have for the study of the electricity markets’ evolution.

Aplicação do modelo de Elton-Gruber para a construção de carteira no índice PSI-20

Os mercados financeiros têm um papel fundamental na dinamização das economias modernas. Às empresas cotadas oferece o capital necessário para impulsionar o seu crescimento e aos investidores individuais proporciona a diversificação das suas carteiras, usufruindo desta forma do crescimento e da vitalidade da economia mundial. A gestão de carteiras de ativos financeiros constitui uma área que procura apresentar mecanismos para a obtenção de uma relação ótima entre retorno e risco. Neste sentido, inúmeros estudos têm contribuído de forma significativa para a eficiência e para a prática desta técnica. Esta dissertação pretende analisar a metodologia desenvolvida por Elton-Gruber para a construção de carteiras otimizadas e aplicar as técnicas subjacentes ao mercado acionista português. Para o efeito, serão realizadas pesquisas em fontes bibliográficas da especialidade e serão consultadas bases de dados de cotações históricas das ações e do índice de mercado nacional. A aplicação incidiu sobre ações cotadas no índice PSI-20 durante o período compreendido entre 2010 e 2014. No intuito de melhorar a compreensão das séries de retornos das amostras, o estudo de caráter quantitativo também recorreu à análise estatística. As evidências mostram que a carteira otimizada, no período em análise, contém apenas as ações da empresa Portucel. Este resultado estará condicionado pelos efeitos da crise financeira que iniciou em 2008.
