The Brazilian Interconnected Power System is hydro dominated and characterized by large reservoirs presenting multi-year regulation capability, arranged in complex cascades over several river basins. In this way, the expansion and operation planning

Power generation planning in hydrothermal systems is a complex optimization task, specially due to the high uncertainty in the inflows to hydro plants. Since it is impossible to traverse the huge scenario tree of the multistage problem, stochastic du

The objective of NEWAVE model, based on stochastic dual dynamic programming algorithm, is to solve the long term operation planning problem of large scale interconnected systems, such as the Brazilian one. The year of 1998 is the milestone for the fi

Traditionally, long-term power generation planning problems has been performed with the main objective of minimizing the expected value of generation and load curtailment costs. However, more recently there has been a need to apply some risk measure

The mid-term operation planning of hydro-thermal power systems needs a large number of synthetic sequences to represent accurately stochastic streamflows. These sequences are generated by a periodic autoregressive model. If the number of synthetic se

2010 IREP Symposium Bulk Power System Dynamics and Control - VIII (IREP).
Currently in Brazil, long-term (horizon 20 to 30 years) and short-term (15 years horizon) energy expansion planning studies are carried out under the coordination of the Ministry of Mines and Energy. More recently the Federal Government has decided t
