Abstract

The system observability enabled by distribution-level PMUs becomes increasingly crucial for cyber-physical security enhancement. We formulate this system observability as a disjunctive relaxed connected dominating set problem for reconfigurable distribution networks with the least defense cost in theory. For the benefits of system observability, an observability defense-constrained distribution network reconfiguration (DNR) model has been proposed. This DNR model is then converted to a mixed integer second-order conic programming problem, which thus can be solved with commercial solvers in case studies.
