    • Bid-based dispatch of hydrothermal systems in competitive markets 

      Lino, Priscila Rochinha; Nobrega Barroso, Luiz Augusto; Veiga Pereira, Mario; Kelman, Rafael; Fampa, Márcia Helena C. (01/04/2003)
      The objective of this work is to investigate possible hydro-scheduling inefficiencies under a bidding scheme. It will be shown that the market-based dispatch of hydro-plants, under a perfect competitive market, converges ...
    • Bilevel optimization applied to strategic pricing in competitive electricity markets 

      Fampa, Márcia Helena C.; Nobrega Barroso, Luiz Augusto; Candal Reis Fernandes, Denise; Simonetti, Luidi Gelabert (01/03/2008)
      In this paper, we present a bilevel programming formulation for the problem of strategic bidding under uncertainty in a wholesale energy market (WEM), where the economic remuneration of each generator depends on the ability ...
    • Market power issues in bid-based hydrothermal dispatch 

      Nobrega Barroso, Luiz Augusto; Fampa, Márcia Helena C.; Kelman, Rafael; Veiga Pereira, Mario; Lino, Priscila Rochinha (01/11/2002)
      The objective of this work is to investigate market power issues in bid-based hydrothermal scheduling. Initially, market power was simulated with a single stage Cournot-Nash equilibrium model. In this static model the ...
    • Nash equilibrium in strategic bidding: a binary expansion approach 

      Nobrega Barroso, Luiz Augusto; Carneiro, Rafael Dix; Granville, Sergio; Veiga Pereira, Mario; Fampa, Márcia Helena C. (01/05/2006)
      This paper presents a mixed integer linear programming solution approach for the equilibrium problem with equilibrium constraints (EPEC) problem of finding the Nash equilibrium (NE) in strategic bidding in short-term ...
    • Strategic bidding under uncertainty: a binary expansion approach 

      Veiga Pereira, Mario; Granville, Sergio; Fampa, Márcia Helena C.; Carneiro, Rafael Dix; Nobrega Barroso, Luiz Augusto (01/02/2005)
      This work presents a binary expansion (BE) solution approach to the problem of strategic bidding under uncertainty in short-term electricity markets. The BE scheme is used to transform the products of variables in the ...
