13. An equivalent 44 kV distribution feeder system in the city of Ottawa (see the following figure) is used. The utility source is 230 kV and the 44 kV substation is connected to the grid via a circuit breaker (CB). The capacity of the substation transformer is 100 MVA (base for per unit calculation). A 20 Mvar capacitor bank is located at the substation. A PV-DG is connected at bus 7. A controllable DG is connected at bus 7. Each load is seen as the equivalent total load in the bus. The feeder conductor parameters are R = 0.1156/km and X = 0.3708 km according to practical feeder parameters in the distribution system.
