Traditionally, bulk power was delivered by the central generation unit to the loads. However at present, Distribution Generation (DG) systems are normally connected at the distribution level and near to the load. This paper presents the modelling of Photovoltaic (PV) and the factors that affect the PV output power. The impact of PV in the distribution feeders operation in different cable capacities and penetration levels are also investigated. The results indicate that the impact of (50-150)% PV system penetration in the case of higher maximum demand is larger than the smaller maximum demand. Losses in systems showed a sharp decline in high penetration with high demand than those in lower levels.

In certain spots on the planet which have less attainable of utilizing enormous breeze power plants, the expressway wind vitality can be utilized to help little loads in the main grids. Interstates road lighting for instance of that heaps that is expending a great deal of vitality and cost every year. When the vitality that originates from vehicles development along the highway avenues can be taken in thought, this paper has examined the outcomes if moment vehicles wind speed during 24 hours per day. 24 hours, brief interim of vehicles wind speeds have been estimated by utilizing anemometer put in the road. A vertical pivot wind turbine (VAWT) has been proposed to be utilized in this task. All venture regulation has been simulated by utilizing Opendss program; it can support time series simulation. The outcomes demonstrated that the undertaking is possible to be utilized in Al-Durra Highway Street. The normal breeze speed of moving vehicles is 4.7 m/s which can deliver 67.3 watt by the proposed turbine. The got energy saw that it as contributed to be utilized by the maingrid during the day time. All the demonstrated bends of the outcomes speak to the Iraq grid support by diminishing the main demand and operational expenses too.
