PROJECT TITLE :

A Novel Tuning Method for Advanced Line Drop Compensator and Its Application to Response Coordination of Distributed Generation With Voltage Regulating Devices

ABSTRACT:

Today, the combination of little-scale electricity generators, referred to as distributed generation (DG), into distribution networks has become increasingly standard. This tendency, along with the falling value of DG units, has a nice potential in giving the DG a better chance to participate within the voltage regulation process, in parallel with alternative regulating devices already accessible in the distribution systems. The voltage management issue seems to be a very challenging downside for distribution engineers since existing management coordination schemes need to be reconsidered to take into consideration the DG operation. During this paper, a brand new tuning technique for the road drop compensator has been proposed, and it's applied for the control coordination of DG with different regulating devices in the network, that is in a position to utilize the ability of the DG as a voltage regulator and, at the same time, minimize the interaction of DG with another DG or alternative active devices like the on-load tap changing transformer (OLTC). The proposed coordination technique has been developed based mostly on the ideas of protection principles (magnitude grading and time grading) for the response coordination of OLTC, DG unit, and different regulating devices. A distribution feeder with a tap changing transformer and DG unit has been extracted from a practical system to test the proposed management technique. The results show that the proposed technique provides an efficient solution for coordination between OLTC and DG, DG-DG, or DG and voltage regulating devices, and the combination of protection principles has considerably reduced the management interaction to attain the specified voltage correction.
