|Title:||Predispatch of hydroelectric power systems with modifications in network topologies|

|Abstract:||Electric grids are operated to ensure the provision and supply of electric power under suitable conditions at a minimum cost. However, the need for maintenance and repairs to equipment and transmission lines employed in the electric grid is constant and increasingly frequent; therefore, studies are necessary in the operational area in order to analyze and to enable the required services. Manipulations in an electric grid are necessary in order to allow preventive or corrective maintenance on the grid, thereby ensuring system operability. In this study, the primal-dual interior-point methods are used to minimize costs and losses in a predispatch model for the generation and transmission of direct current (DC) power flow in a hydroelectric system with pre-programmed manipulations; i.e., in cases of preventive maintenance, within a period of 24 h. From the computational standpoint, the effort required to solve a problem with and without manipulations is similar, and the reasons why will be also discussed in this study. Computational results corroborates these findings|
