Micro-grids have spread in many distribution systems worldwide. Microgrids are operated by a customer or
a group of customers for having a reliable, clean and economic mode of power supply to meet their demand.
Furthermore, micro-grids can help in integrating and promoting for Renewable Energy Sources (RES) and reducing the
environmental impacts of traditional centralized generation. This paper presents an economic and emission dispatch
problem solution using Ant Colony optimization of micro-grids. An isolated micro-grid with solar is considered in this
paper. A combined cost optimization scheme is investigated to minimize both operational cost and emission levels while
satisfying the micro-grid’s load demand. The effects on total generation cost, with the inclusion of solar energy into a
micro-grid is studied and found the most profitable solution by considering different practical scenarios. The Ant Colony
was implemented using MatLab and tested on two case studies with and without RES-Solar energy (PV). The obtained
results from the Ant Colony technique are compared with those calculated using other Techniques; Gradient method. The
outcomes are evaluated and discussed
