Wind power has shown marked increase both in the world and in Japan. However, since wind power generation has distinct characteristics—e.g., intermittency of output power—from conventional power source, its large-scale integration provokes concerns on its adverse effects on an electricity grid. In Japan, governmental committees have discussed the effects and recommended the researches on the following topics: output fluctuation characteristics of wind power, stabilization of output fluctuation of wind power with energy storage technologies, wind power prediction, etc.
The article summarizes the results of the researches as well as the researches in Japan on control methods of wind power and an electricity grid frequently examined in the papers of IEEJ Transactions on Power and Energy.
