State estimation of IEEE 14 bus with interphase power controller using WLS method

Traditional state estimation methods are not well suited for power systems with FACTS devices. A novel approach to state estimation of systems with interphase power controllers (IPC) is proposed. The extension of the conventional model of the system necessitates the use of constraints accounting for limits associated with the IPC operation and ratings. Results of tests on the IEEE 14 bus system using the weighted least-square method, have confirmed validity of the proposed approach.
