Japan has been experiencing a rapid deployment of photovoltaics (PVs) since the Feed-In Tariff (FIT) Scheme for Renewable Energy was launched in July 2012 . The increasing penetration levels of variable renewable generation, especially PVs and wind, have been affecting power system operations in each of Japan's 10 balancing areas. To accommodate this rapid growth in variable generation, the government established the Working Group on Grid Connection of Renewable Energy in 2014 to continually discuss and make timely decisions about these operational issues, including capacity connections, operation enhancement and asset improvement in each balancing area, and inevitable curtailment procedures for renewable generation.

使可再生能源运转：日本可再生能源作为主要动力源的操作实践和未来挑战

自2012年7月启动可再生能源上网电价（FIT）计划以来，日本一直在快速部署光伏（PV）。可变可再生能源（尤其是光伏发电和风能）的渗透率不断提高，已经影响了日本10个平衡地区中每个电力系统的运行。为了适应发电量的快速增长，政府于2014年成立了可再生能源并网工作组，以就这些运营问题持续讨论并及时做出决策，包括各个平衡领域的容量连接，运营增强和资产改善，以及可再生能源的必然削减程序。
