Autor: Ivo Chaves da Silva Junior, André L. M. Marcato, Tales Pulinho Ramos, Bruno Henriques Dias, Rafael B. S. Brandi

Publikováno v: IEEE Transactions on Power Systems. 33:3678-3690

The long-term operation planning problem is generally solved by a chain of computational models based on Stochastic Dual Dynamic Programming (SDDP) considering a period of 5–10 years ahead. A recent issue that has arisen concerning this problem is

Comparison between piecewise linear and non-linear approximations applied to the disaggregation of hydraulic generation in long-term operation planning

Autor: Bruno Henriques Dias, Ivo Chaves da Silva Junior, Rafael B. S. Brandi, André L. M. Marcato, Tales Pulinho Ramos

Publikováno v: International Journal of Electrical Power & Energy Systems. 71:364-372

This paper presents a comparison of two proposed approaches to model the hydropower production functions (HPF) applied to long-term operation planning problems. The first approach consists of a non-linear approximation that uses a sigmoid function, a

Improving stochastic dynamic programming on hydrothermal systems through an iterative process

Autor: André L. M. Marcato, Rafael B. S. Brandi, Ivo Chaves da Silva Junior, Bruno Henriques Dias, Tales Pulinho Ramos

Publikováno v: Electric Power Systems Research. 123:147-153

This paper proposes an iterative process to select the cuts that model the cost-to-go functions of stochastic dynamic programming (SDP) and stochastic dual dynamic programming (SDDP) algorithms. This approach is applied to the medium/long-term operat
