Economic Dispatch of Microgrid based on Multi-Agent System

The evolution of renewable energies and their adoption by the traditional energy system (ES) under the role of distributed generation has driven the interest to management strategies based on distributed algorithms. In this sense, simulation and optimization models able to integrate the intermittent behaviour of wind and solar generation into ES model have become a necessity, in order to incorporate the interactions between power sources and the communication infrastructure in an effective manner. In this paper, a simulation model based on consensus algorithm for the optimal management of autonomous system is described. Important features related to the generation cost and the availability of renewable resources are discussed by means of a case study of a microgrid located in Zaragoza, Spain.
