An analysis carried out using HOMER Pro simulator shows that the solar photovoltaic is an affordable and reliable option for this community. The solar irradiance profile in the area showed the viability of solar energy in comparison to other renewable energy sources considered within these specific environmental conditions. In this research study, various renewable energy resources have been examined in order to identify the most locally practical renewable energy technology for household lighting needs. The villagers in Chibayish require artificial light for their indoor living areas after dark and also for night fishing, which is a common practice. The Chibayish unique house building technique of man-made islands (floating baskets), results that these floating houses are not connected to the Iraqi national grid. However, it is challenging to implement a clean and renewable energy lighting system for a small community like Chibayish in the Iraqi marshes. Like other countries around the world, the Iraqi government has realized the importance of climate change and the necessity for clean energy which has led them to officially ratifying the Kyoto Protocol in January 2008. Lighting is a major aspect of human energy consumption and access to quality lighting is one of the most important indicators of human development.

Outage!!! Grid-connected system? Don’t worry, be happy! Applies to system with large battery banks.Furat Dawood *, Tania Urmee and G.M. Provides safety margin ensures reliable electricity supply despite variability in electric load & renewable power supply.
Cycle charging Whenever generator operates, extra electricity is produced to charge the battery while serving the load.ġ1 Operating Reserve = Operating capacity – Electrical load Battery is only charged by surplus electricity. Load-following Renewable energy charges the battery, generator does not. Minimum state of charge Round trip efficiencyġ0 Dispatch Strategies How the battery is charged. If it is not scheduled, HOMER decides whether it should operate based on the needs of the system & the relative costs of the other power sources.ĩ Battery Bank Nominal voltage Capacity curve Lifetime curve The modeler may decide that one of those suboptimal configurations is preferable in some way to the configuration that HOMER represents as optimal.ħ Physical Modeling How HOMER models the physical operations of the system? Loads Resources ComponentsĨ Generators Can be scheduled to force it ON or OFF at certain times.
The overall optimization results tends to show many system configurations whose NPC is slightly higher than that of the optimal configurations. The optimal configuration is the one that satisfies the user-specified constraints at the lowest NPC. Includes initial capital cost of components, cost of replacement, maintenance & fuel, & cost of purchasing power from the grid. Includes all costs and revenues within the project lifetime, with future cash flow discounted to the present. Sensitivity analysis: Performs multiple optimizations with different input assumptions to gauge the effect of uncertainties.ĥ NPC Total Net Present Cost Represent life-cycle cost. Optimization: Determines the best possible system configuration. Availability of renewable resourcesĤ 3 Principle tasks Simulation: Models the system & determine technical feasibility & life cycle cost. Key parameters: Load size & fuel price Power output: Intermittent, seasonal. Compare different design options based on their technical & economic merits, including input uncertainties.ģ Why use HOMER? To overcome uncertainties: Design options
