A Distributed Stabilizing Economic Dispatch Control for Energy Storage Unit based Autonomous Microgrid

Contrôle de répartition économique stabilisant distribué pour un micro-réseau autonome basé sur des unités de stockage d'énergie.

Abstract

In this paper, a fully distributed control-based consensus method is used to ensure a stabilizing Economic Dispatch (ED) for different Distributed Energy Storage System (DESS) technologies while achieving frequency and voltage regulation of Distributed Generators (DGs). All DESSs, as agents, work together to minimize the total generation cost (TGC) of the islanded Microgrid (MG) by applying the principle of equal incremental cost in the consensus algorithm. The consensus algorithm provides the optimal active powers to all DGs which are sent to the droop control. These optimal active power references are chosen to regulate the DG frequency to the nominal frequency of the MG. Therefore, the proposed method ensures optimal economic dispatch with automatic frequency restoration. A MATLAB/Simulink simulation is performed in order to verify the effectiveness of the proposed method in case of load variation. A comparison between the proposed ED method and the ED control used in a decentralized architecture controller is also provided to show the contributions of the proposed method.
