A Decomposition Method for Multi-Area OPF Problem

This paper presents a decomposition method for multi-area optimal power flow (OPF) problem. Applying this method to the multi-area OPF problem will yield an optimal coordinated but decentralized solution. The proposed method is efficient in solving the OPF problem with limited data exchange between areas. The developed method is successfully implemented and tested using the 3 area IEEE 30 bus test system. Numerical results comparing the solutions obtained by the traditional and the proposed decentralized methods are presented for validation
