Abstract
A method for optimal power system voltage and reactive power management which takes into account control of the interconnection reactive power flows is presented in this paper. The need for such control is evident as the voltage and reactive power scheduling in one power system can have serious impacts, including very negative, on the neighboring power systems. Moreover, according to the ENTSO-E network code, the neighboring transmission system operators (TSOs) should commonly define the reactive power flow limits on the interconnectors. The proposed solution is based on a modified single-area reactive power optimization (RPO) method. Reactive power flow constraints on the interconnectors were implemented in the reactive power control model. The presented approach does not require complex coordination or exchange of information between the neighboring TSOs, and is easy to implement. The efficiency of the presented method is evaluated using the New England 39-bus system.
