Iraq energy storage microgrid

What is an energy microgrid?

A microgrid is a small electricity generation and distribution system containing distributed generation, energy storage systems, loads and monitoring and protection devices. It is an autonomous system that is self-controlled and self-managed. An energy microgrid provides users thermal energy for heating and cooling in addition to electricity.

How much does energy storage cost a microgrid?

In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.

Can a solar PV microgrid supply a load during a power outage?

This paper aims to analyze the techno-economic and environmental feasibility of a solar PV microgrid system which is able to supply the load during both grid availability and outage periods. A household in Baghdad was selected as a case study. HOMER software was used to carry out the overall analysis using five different control strategies.

What is a grid interconnection charge?

A grid interconnection charge of $100 was applied which is a one-time fee paid by the customers to the utility for permitting the installation of the PV system to the national grid [ 47 ]. 2.5. System control To control the flow of energy, an overall energy management system is required.

How much solar radiation does Iraq get a year?

Iraq is strategically located in the world’s solar belt so it is fortunate to receive large amounts of incident solar radiation more than 3000 h of bright sunshine per year, with average daily sunshine for 11–12 h in summer and 7–8 h in winter. The hourly solar intensity in Baghdad ranges between 416 W/m2 in January and 833 W/m 2 in June.

Do PV degradation and grid outage frequency affect system performance?

The sensitivity analysis performed on the economically optimized system indicated that the variations in PV degradation and grid outage frequency have a significant influence on the behavior of the system.
