Title:
SYSTEM AND METHOD FOR SIMULATING FLUCTUATIONS IN OUTPUT OF DISTRIBUTED POWER SUPPLY
Document Type and Number:
Japanese Patent JP2004282878
Kind Code:
A
Abstract:

To simulate fluctuations in the output of a distributed power supply, in a manner close to reality.

For natural energy amount generated by a natural energy amount generator 101, a basic characteristic model 102 generates a theoretical output determined by the power generation performance characteristics of generator and outputs it. For natural energy amount, an output fluctuation simulating unit 104 simulates an output fluctuation content, according to probability distribution (e.g., normal distribution) as the fluctuation content of the theoretical output, determined by the power generation performance characteristics of the generator, and outputs it. An adder 103 adds the output of the basic characteristic model 102 and the output of the output fluctuation simulating unit 104, to simulate uncertain output fluctuations, as are observed in actual equipment. In the basis of the result of this simulation, an electric power system is analyzed by the fluctuations in the output of realistic distributed power supplies.
