要約(英語): A voltage rise problem in distribution network has been discussed as the foremost concern against the penetration of large amount of photovoltaics (PVs). The authors focus on latent ability of the present distribution network and PVs to find a low cost solution against the problem and consider a solution to mitigate the voltage rise using PV's constant leading power factor operation. So far, as a result of having simulated with an aggregated model of real distribution network, we proposed that a combination of PV's constant leading power factor operation and LDC makes it possible to maintain the line voltage and LTC tap position adequately. In this paper, additionally, the authors confirmed some effects of the proposed method in an aggregated model of distribution network and trunk power system. One of them is the proposed method reduces the frequency of restricting output power from PVs and changing LTC and SVR tap position, although PVs are rapidly fluctuated. Another is the proposed method can't make a great impact for trunk power system of a voltage class exceeding 6.6kV.
