Real Power Dispatch on Large Scale Power Systems by Augmented Lagrange Hopfield Network

This paper proposes an augmented Lagrange Hopfield network (ALHN) for real power dispatch on large-scale power systems. The proposed ALHN is a continuous Hopfield network with its energy function based on augmented Lagrange function. For this combination, the ALHN method can easily deal with large-scale problems with nonlinear constraints. The proposed ALHN has been tested on systems from 40 units to 240 units, IEEE 118-bus and IEEE 300-bus systems, and the obtained results have been compared to those from other methods. The test results have shown that the ALHN method can obtain better solutions than the compared methods in a very fast manner. Therefore, the proposed ALHN could be favorable for implementation on the real power dispatch problems for large-scale systems.
