The paradigm of production and distribution of energy has recently been modified by the expansion of green technologies in response to economic, technical and environmental issues presented in the conventional technology. Developing and integrating decentralized, controlled and well-defined MicroGrids (MG) is the trend in order to operate either in grid-connected and islanded mode, as well as in AC or DC configuration. A MG consists of loads, converters and Distributed Energy Resources (DER) such as Distributed Generators (DG), Distributed Storage (DS) or controllable loads.
A hierarchical control scheme of three-level for intelligent MG has recently worked to increase the reliability and flexibility, but most research has been developed in the first two levels that manage a local control on the issues of stability and power quality. Tertiary control deals with optimal operation and power flow management. This project will be focus on tertiary level of control and will develop management strategy for scheduling the resources of MG by implementing Energy Management System (EMS) in order to coordinate generation, storage and use of energy.
A proper Energy Management System will be obtained in order to schedule the use of the resources, compensate the effects of load fluctuations and intermittency of renewable energy generators and trade-off with the user necessities. Therefore, it is expected to obtain a proper scheme to provide secondary control with the reference to work accurately.
