要約(英語): Voltage rise problem in distribution networks has been discussed as the foremost concern against the penetration of large amount of photovoltaics (PVs). As a solution of such problem, using voltage regulation facility such as SVC (Static Var Compensator) or Loop power flow controller are proposed. However, it might require major investments in the distribution network and that means the cost would be imposed on the nation.In this paper, the authors focus on latent ability of the present distribution network and PVs to find solution against the problem and propose a low cost solution to mitigate the voltage rise by using constant leading power factor operation of PVs. The distribution voltages are calculated in case of increasing highly penetrated PVs, where it is very important to make an aggregated model of the distribution networks including loads and PVs. The authors aggregate a lot of loads and PVs by using an aggregation method called “Y-connection”. As a result of having simulated with the aggregated realistic model of distribution networks, the authors confirmed that using a combination of leading power factor operation by Q = -0.2P and LDC of distribution transformer make it possible to maintain adequate voltage without voltage regulation facility such as SVC.
