Recent years, many issues about voltage and power quality arise in distribution lines by the spread of distributed power supplies. To cope with this, many voltage control techniques of the voltage regulator for distribution line have been developed for each problem, but there are few examples which were compiled about their application point and future problems in the form that covered all these techniques, while comparing the characteristic and cost. In this report, for the purpose of contributing to the future technology development and the operation of the power distribution, we compile the characteristic, advantages and disadvantages of these main techniques of the voltage regulator which are really used, and propose some new techniques and products which we have developed in order to cope with the voltage control that will become more difficult in future.
