A fast response algorithm has been developed for active-power dispatch to microsources in a distributed generation microgrid. It is capable of adjusting microgrid generation to demand on-line in grid-connected-mode. The algorithm performs an optimization of fuel consumption and emissions costs functions, of microsources using a heuristic approach. It and has been tested to solve different power dispatch cost optimization problems. The tests realized show a maximum execution time of about 1 ms, which is several orders of magnitude faster than the results obtained with other state-of-the-art optimization methods currently employed in these applications. It has also shown better performance in terms of global cost and microsources stability. The fast response implies a substantial reduction of the computational resources needed, allowing the use of a low-cost programmable logic controller or microcontroller for microsources active power dispatching. Thus, the infrastructure requirements and new investments are reduced and the penetration of microgrids based on renewable energies is improved. |
