English Abstract

Globally there is a lot of academic interest in cleaning up the process of power generation.

In the Kurdistan region to the north of Iraq there is a high potential for renewable energy power generation.

Solar insolation reaches an annual average of 5.27 kWhr/m2/day.

Wind energy is plentiful and wind speed can achieve an annual average of up to 7 m/s at a height of 100 m from the ground.

Also there are over 60 proposed locations that have been marked for dam locations in Erbil, one of the three northern provinces of the country alone.

There is a large need for additional power (from 25 to 45%) and combining all available resources in a hybrid network for power generation can substantially reduce the need for grid connection.

This paper investigates the simulation of two micro hybrid systems, for up to 3 kW of electric power generation, using hybrid optimization model for electric renewables, known as HOMER.

One located in a metropolitan area, to compensate for interrupted power supply and appointed as deferrable load in the simulation, combining the merits of solar panels with a backup diesel generator.

The other located in an off grid area, supplied by micro-hydro generation, solar PV system, a wind turbine and a standby diesel generator.

A cost of 1.4 $/Watt is the minimum estimated amount for the PV system and the optimum angle for around-the-year performance was established to be; facing south at 36o inclination angle from horizontal.

The standalone scenario at remote area achieved better sustainability results, where the load was shared up to 19% by PV system, wind energy produced up to 51%, micro hydro-turbine about 28% and the diesel generator was needed for only 2% of the demand.

The metropolitan system divided the load during the interrupted power by 52% for PV system and 48% for the diesel generator.

The resourcefulness of the remote area case led to the reduction of diesel generator emissions by (13) times.
