- multiple feeders. In the proposed method, the LTC tap positions are determined by the method in [3-4] and on/off status of the SC is fixed by the reactive power flows at the substation and the LTC tap position in an on-line manner.
- (9) are identical to the number of ULTC taps(比), which does not contribute to the computational burden of the problems. In this paper, we first solve the problem using the Quasi-NR method, which finds an optimal SEV, then locates the two ULTC tap positions that are fit to the optimal SEV. Finally, one of these candidate tap positions could be selected as an optimal tap position.
- The proposed control schemes of the LTC transformer improve the voltage regulation over the multiple feeders at the distribution substation while those of the SC enhance the power factor at the substation and reduce the tap changing operation of the LTC transformer. The main features of the proposed schemes are the volt/var regulation for the multiple feeders with the unbalanced load diversity, which is common in real distribution network. The simulation results indicate that the proposed cooperation schemes are very efficient for distribution substations with the LTC and SC to regulate the distribution volt/var.
이론/모형
- In the proposed method, the LTC tap positions are determined by the method in [3, 4], called the Multiple Line Drop Compensation (MLDC) method, and on/off status of the shunt capacitors is determined by the reactive power flows at the substations and the LTC tap position in an on-line manner.
