Priority List Method Aided Artificial Bee Colony Algorithm for Optimal Operation Off-grid Microgrid

Micro Grid (MG) is defined as an assembly of renewable energy sources (RES) such as wind energy and non-RESs (micro sources) such as micro turbine and fuel cells. MG can provide electrical power for rural and remote areas where supplying the from the grid is not economical and feasible. MG can be operated either as connected to a grid or independent from it. The work proposes a two-stage methodology for the cost-effective operation of off-grid MG systems. The incremental cost-based unit selection and artificial bee colony algorithm are utilized for the determining the real power outputs of online power sources. The developed methodology is implemented on two off-grid MG systems and the attained best feasible dispatch schedules are various scenarios are presented.
