Abstract
As power systems generally are large interconnected systems controlled by
several parties, centralized optimal power flow (OPF) control taking the entire
grid into account is often not feasible. To use optimal control in power
systems nevertheless, the overall system is decomposed into areas with
associated subproblems, which are solved in an iterative way. Currently
available decomposition techniques assume that the models and control
objectives of areas are formulated to be non-overlapping, i.e., the border of
one area is at the same time also the border of a neighboring area. However,
when the areas are determined independently from each other, e.g., by
sensitivity analysis, the areas can be overlapping, making currently existing
techniques not directly applicable. In this paper, we extend one of these
techniques, viz. a modified Lagrange decomposition method, to the case of
overlapping areas. Simulations are carried out on an adjusted IEEE 57-bus
system in which the controlled entities are FACTS devices and the objective is
to improve system security.
