A Mixed Integer SDP Method for Optimal Meter Placement in Power Transmission Systems

This paper proposes an optimization method to optimally place meters in transmission systems aiming at enhanced state estimation accuracy and minimized number of installed meters. Two optimization criteria are considered for the meter placement formulation, both yielding objective functions with integer decision variables subject to linear matrix inequality constraints. An efficient mixed integer semidefinite programming algorithm is used for solving the problem. The validity of the proposed method is evaluated via numerical simulations on the IEEE 14- and 30- bus benchmark systems.
