Abstract :
The actual lines have many operation problems like power flow distribution, oscillations, etc. A bad power flow distribution on the network lines appears for example during a fault, in this case is possible that some lines of the network would be overloaded and other lines under their thermal value. A possible solution of the problem is using series compensators to redistribute the power flow, the converters are bypassed until the fault appears and after this, it start to compensate. Evolutive algorithms can solve the problem of the ubication in the network of these converters and to chose the power of it too, minimizing the total installed power to make that power flow redistribution. This paper presents an evolutive algorithm that solves the problem of placing SSSC converters in a network to optimize the power flow across all the lines of those network, minimizing the total installed power when a line of the network falls. The number of converters to be placed and their power will be chosen by the algorithm too.
