Design of synchrophasor estimation systems with convex semi-infinite programming

Abstract

In this paper, we present a design methodology for synchrophasor estimation systems based on a convex semi-infinite optimization approach. Concretely, we present a suitable objective function for the problem and show how different performance constraints can be formulated. The advantage of this over most methods is that it allows us to control precisely and completely the behavior of the system on both frequency and time domains. Thus, it gives an optimal and extremely flexible tool for a designer who wishes to obtain a particular desired performance. In particular, we show the advantages of this methodology by comparing it with standard designs on a study case on the basisof the IEEE Std. C37.118.1-2011.
