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

Journal Article


Abstract


  • Nowadays, the integration of small-scale electricity generators, known as distributed generation (DG), into distribution networks has become increasingly popular. This tendency, together with the falling price of DG units, has a great potential in giving the DG a better chance to participate in the voltage regulation process, in parallel with other regulating devices already available in the distribution systems. The voltage control issue turns out to be a very challenging problem for distribution engineers since existing control coordination schemes need to be reconsidered to take into account the DG operation. In this paper, a new tuning method for the line drop compensator has been proposed, and it is applied for the control coordination of DG with other regulating devices in the network, which is able 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 other active devices such as the on-load tap changing transformer (OLTC). The proposed coordination technique has been developed based on the concepts of protection principles (magnitude grading and time grading) for the response coordination of OLTC, DG unit, and other regulating devices. A distribution feeder with a tap changing transformer and DG unit has been extracted from a practical system to test the proposed control technique. The results show that the proposed method provides an effective solution for coordination between OLTC and DG, DG-DG, or DG and voltage regulating devices, and the integration of protection principles has considerably reduced the control interaction to achieve the desired voltage correction.
