Abstract
In this paper, a new algorithm for decentralized OPF is proposed, which is based on decomposition of KKT conditions of the global OPF. As implicit functions adopted, a boundary optimal problem is coined to formulate the global OPF in the decomposition and coordination manner. An improved inner-point method is applied to solve this boundary optimal problem, which makes use of a Jacobian-Free Newton GMRES(m) method to enhance its convergence rates as well as to reduce the communication costs. The IEEE 39 and 118 bus systems are used for case studies. Test results prove that the proposed decentralized OPF algorithm has strong convergence and requires small communication costs, which makes it feasible in wide area network environments.
