Power network management system and power network management method

摘要

PPROBLEM TO BE SOLVED: To implement an electric power network management system wherein an electric power network which is supplied with generated output from a plurality of natural energy generating sets (e.g. photovoltaic power generator, wind turbine generator) is stabilized. PSOLUTION: The controller 15 for each natural energy generator system 1 predicts the electricity generated for an expected date of power generation based on weather information for the expected date of power generation according to weather forecasting or the present season and predetermined electricity generated information. In addition, the controller 15 predicts the power consumption of a load 14 for the expected date of power generation based on the weather information, present season, or the expected data of power generation or its day of the week and predetermined power consumption information. An electric power network management apparatus 3 determines the amount of power supply of each natural energy generator system 1 based on the predicted electricity generated and power consumption, so that the sum of the amounts of power supply to the electric power network 2 becomes constant in the expected date of power generation.
