In this letter, we propose a third order sliding mode observer-based approach for optimal load frequency control in power networks which are partitioned into control areas. We model each area by an equivalent generator including second-order turbine-governor dynamics. Assuming to measure only few state variables, we design two third order sliding mode observers for each control area to locally estimate...
In this paper an estimation scheme for a power grid based on distributed observers is presented. Assuming that the only measurements available are the generator phase angles, our approach allows us to consider an observer for each bus of the power grid, exploiting on only knowledge of local information about the power system. In particular, we design a super-twisting-like sliding mode observer for...
