The paper presents an energy approach based on controllability and observability gramians for the optimal location of controllers/sensors in large-scale power systems. This approach consists of solving a stochastic optimization problem based on scenarios reflecting various operational situations (load changes, line tripping…). This approach could be regarded as part of a structural optimization procedure aiming at defining some new control systems in the context of security improvements of large-scale power systems. Application to the "Two-area power system" gives very promising results.
Keywords: balancing realization reduction; controllability gramians; observability gramians; optimal location of controllers/sensors power system
