In this paper, we propose a distributed computational algorithm for solving the distributed optimal power flow problem under deregulated environment. Except for the data of the self-subsystem, the proposed distributed algorithm requires only the data of the boundary buses of the connecting subsystems. Therefore, it is easily implemented in a computer network. We have tested the proposed distributed algorithm on the IEEE 118-bus system, which is arbitrarily partitioned into four subsystems. The test results demonstrate the convergence and the computational efficiency of the proposed distributed algorithm.
