Optimal phase shifter calculation based on adaptive genetic algorithm

In order to solve the problems of unbalanced power transmission on grids, one of flexible AC transmission system： phase shifter was investigated. On the basis of analyzing its principles and applications, the site selection of phase shifter optimization was researched. The method for site selection based on resolving over-load or heavy-load of power grid was put forward, this method was divided by two steps ： pre- liminary screening based on power flow margin and site selection based on utilizing rate of transmission lines. The analysis result of site selec- tion optimization for IEEE57 bus system under typical operating mode shows that the proposed index and method are highly efficient and val- id, and shows the system reliability can be greatly improved.
