Development of an intelligent energy management system with economic dispatch of a standalone microgrid

Abstract EN

Microgrid concept has been widely used for grid connected distributed energy resources.

That can operate either connected or disconnected from the main grid during grid failures.

Such integration presents new challenges to microgird operations.

Therefore, an energy management system is an essential factor for optimal energy scheduling of these distributed energy resources.

This paper presents a new control approach for optimal energy management and economic dispatch of a standalone microgrid.

Typical results are presented with initial state of charge, load profile and meteorological conditions as variables parameters, and the performance of the proposed system is evaluated in three case studies considering power balancing, maximizing the utilization of renewable energy, monitoring the battery state of charge, fuel cost optimization, real time information exchanges and satisfying the system objective constraints.
