<P>PROBLEM TO BE SOLVED: To provide a method for correcting inequality in an output suppression amount between users (houses) only by adding a function to an existing apparatus in a power distribution system with multiple interconnected photovoltaic power generation systems. <P>SOLUTION: A method for avoiding output suppression according to the present invention comprises: measuring end voltages of PCSs 7 of all houses 5 in a district where multiple photovoltaic power generation systems 6 are interconnected to the power distribution system at a certain time; calculating a difference between the end voltage at the PCS 7 of the house 5 which shows the highest voltage and 107.5 V which is a preset power management value; and setting an operation voltage for voltage rise suppression function to the PCS 7 of each house 5 by setting the set value of the PCS 7 of the house 5 which shows the highest voltage at 107.5 V and setting the set value of the PCS 7 of each of the other houses at a voltage obtained by adding the difference to each measured voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
