DISTRIBUTION SYSTEM POWER FLOW SIMULATION DEVICE, DISTRIBUTION SYSTEM POWER FLOW SIMULATION METHOD, AND PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To perform distribution system power flow simulation which considers a consumed electric power by a customer and a reversal power flow respectively.;SOLUTION: A distribution system power flow simulation device 100 includes: a distribution system power flow calculation part 10 which calculates a power flow in a distribution system from a substation 1 to a pole transformer 5 using a load power at the pole transformer 5; a customer load simulation part 80 which simulates a time fluctuation of the load power which the customer uses; a distributed power source simulation part 90 which simulates time fluctuation of generated power that is generated by the distributed power sources; and a system state managing part 30 which acquires a load power or a generated power at a specified time point from a plurality of customer load simulation parts 80 and distributed power source simulation parts 90, calculates a load power at respective pole transformers 5 arranged in the distribution system by using the acquired load power and generated power, and inputs the calculated load power at the pole transformer 5 to the distribution system power flow calculation part 10, to make the distribution system power flow calculation part 10 execute power flow calculation.;COPYRIGHT: (C)2012,JPO&INPIT
