Abstract
The optimal operation of a standalone microgrid is often governed by the central controller, which optimizes the set-points of the local controllers of the distributed generators based on the available and predicted data. However, due to the uncertainty of loads and renewable generations, the optimized set-points may not be valid for long periods. This paper proposes a technique to readjust the dispatch of the suitable generation units, between the optimizations, to support load changes. To this end, the potential field concept is used by the loads to select the suitable generation units to make the decision making very quick. The decision is made based on different criteria such as cost, reliability, emission, and power loss. This process requires low computational efforts and can be done instantly. Besides, a periodic optimization is performed by the MG's central controller to retune the whole system and reconfirm the optimal operation. Numerical analysis has been carried out on a sample microgrid to validate the performance of the proposed technique.
