A next century's perspective on growth of electric power system and application of power electronics technologies in Japan

摘要

A task force was established at the Central Research Institute of Electric Power Industry (CRIEPI), Japan, in order to observe the general image of the electric power system of Japan in the mid 21st century. The main results of its investigation can be outlined in the following three points: (i) regarding future energy consumption, it was estimated that demand growth will become gradually saturated within approximately 1.5 times of the present demand by mid 21st century; (ii) the total installed generation capacity required for the supply at the time of saturation will amount to 300 GW; and (iii) according to the demand growth, the electric power system is required to be enlarged to 1.5-2.0 times that of existing systems by the adoption of power system enhancement measures such as power electronics technologies including FACTS, power converters and advanced HVDC systems.
