<span lang="EN-US">Proper employment of Hybrid Wind/ PV system is often implemented near the load, and it is linked with the grid to study dynamic stability analysis. Generally, instability is because of sudden load demand variant and variant in renewable sources generation. As well as, weather variation creates several factors that affect the operation of the integrated hybrid system. So this paper introduces output result of a PV /wind via power electronic technique; DC chopper; that is linked to Iraqi power system to promote the facilitating achievement of Wind/ PV voltage. Moreover, PSS/E is used to study dynamic power stability for hybrid system which is attached to an effective region of Iraqi Network. The hybrid system is connected to Amara Old bus and fault bus is achieved to that bus and the stability results reflects that settling time after disturbance is not satisfactory. But, it is found that PV/wind generation system influences Iraqi grid stability to be better than that with only PV generation and the latter is better than stability of the grid that is enhanced with only wind generation. These results represent an important guideline for Iraqi power system planner.</span>

“…Due to the drawbacks in using position sensors in PMSG drives in WECS, there has been great interest in position sensorless operation which can reduce the instability brought by mechanical sensors and cut the cost of the system. There are basically two typical rectifying topologies for PMSG control: (1) PMSG system with an uncontrollable three-phase diode rectifier followed by a DC chopper [1]. (2) A more efficient PMSG system with a fully controllable IGBT PWM converter.…”

This paper presents a position sensorless operating method in WECS (Wind Energy Conversion System) based on PMSG (Permanent Magnet Synchronous Generator). A position sensorless operating method for direct-drive PMSG using sliding mode observer is proposed. With this method, position angles can be estimated only by measuring phase voltages and currents. By analyzing the cause of angle error, which increases when the PMSG is operating at high speed, a new dynamic angular compensation solution is developed. This method proves to be effective and necessary by experiments based on simulink.
