A microgrid control system is required to efficiently monitor and optimally operate a microgrid with Distributed Energy Resources (DERs) and storage devices. This control system should provide several functions to be able to reliably and optimally manage the microgrid. A general architecture is proposed comprising of the local and supervisory controllers, communication system, enhanced Human Machine Interface (HMI) and forecasting server. The role of each element of control system is described. The potential integration of the microgrid protection and control systems is discussed. Implementation and performance to date of a control system into a remote, isolated grid is presented.
