A power system power flow simulator includes a power system power flow calculator using load power in local voltage transformers to calculate power flow in power system extending from a transformer substation to local power transformers, customer load imitators which calculate time change of load power used by customers, dispersed power source imitators which calculate time change of power generated by dispersed power sources and a system status manager which manages operation procedure. The system status manager advances processing while supplying a load power request message with time information attached thereto to the customer load imitators and the dispersed power source imitators, and decides time intervals of supply of the load power request message in accordance with the power load temporal change rate calculated by the customer load imitators and the dispersed power source imitators.
