要約(日本語): As an alternative, the appropriate size of DG can be achieved via the Optimal Power Flow (OPF) that treats DG as another electric source in addition to the utility substation. The size of DG can be obtained from the dispatched result that is subject to the appropriate constraints. However, installing DG into distribution system can cause protection conflicts. The existing settings of protection devices may be inapplicable. The protection coordination will be lost if fault current flowing through any protective device is changed. As a result, the calculation should take into account the protection coordination criteria. Interesting cases of such problem are discussed together with the solution.
