電力供給リスク低減効果を考慮した分散型電源導入量の最適化

抄録

Renewable energy, which has been increasingly introduced in recent years, not only emits less carbon dioxide, but can also be expected to have the effect of reducing the risk of power supply in the event of a natural disaster as a distributed power source. In this study, after estimating the damage probability of power facilities in the event of a natural disaster, a simulation of the power supply risk in the event of a disaster was performed for the power system in the Tohoku region. As a result of the simulation, the risk for Miyako City in Iwate Prefecture was high, so we assumed that Miyako City would introduce solar power generation and wind power generation as renewable energy, and calculated the risk reduction effect according to the amount of introduction. In addition to the risk reduction effect, we also considered the cost of introducing power sources, conducted an economic evaluation, and calculated the optimal amount of renewable energy to be introduced. As a result of the calculation, the economic evaluation was the highest when 70 MW of solar power generation and 20 MW of wind power generation were introduced.
