Distributed Optimal Dispatch of Multiple Networked Generators

This paper considers the distributed optimal dispatch problem for a group of power generators. The goal is to allocate the total power generations among the distributed generators, while minimizing the total cost and ensuring operation within individual generator capacity limit. By utilizing the consensus-based techniques, we propose a new distributed solution to the traditional economical dispatch problem. In contrast to the existing economic dispatch solutions, the proposed algorithm achieves the finite-time convergence property. To realize the fast and distributed economic dispatch is essential for the future power systems with the high penetration of renewable energy. The simulation results based on a standard IEEE test system demonstrate the effectiveness of the proposed algorithm.
