abstract

  • The effect of flexible hydropower management on prices is a topic widely studied in research and economic analysis. However, the influence of transmission constraints and zonal prices on optimal hydro dispatching has not been highly considered in the literature. In the present study, an iterative algorithm for calculating the optimal bids of hydro plants in a basin is proposed, considering the fundamental influence of these plants in regions when transmission lines are congested and can affect zonal prices. The results show the efficiency of the algorithm and modifications in positioning of hydro plants in the market. (C) 2015 Elsevier B.V. All rights reserved.
