- Abstract
Since photovoltaic generators (PV) have been mainly introduced in residential areas, it is necessary to consider the consequences of setting up large numbers of PVs locally. In such a situation, it will be difficult to manage the voltage in distribution lines, because the reverse power supplied from the PV raises the voltage of the power lines. In this study, a large PV system was connected to a distribution system, and for every inverter the authors used simulations to verify the appraisal of systematic voltage and the electric power generation. As a result, the authors verified that power factor control is more effective than output control. In addition, the authors verified that with each user the power generation becomes more unequal. In the future, when a large PV system is connected to a distribution system, the problem of unsatisfactory equalization of demand for home appliance usage may arise. A method for determining the set value for the inverter for each user was proposed in order to solve this problem, and the effectiveness of the proposed technique was verified through simulations. © 2009 Wiley Periodicals, Inc.
