Desirable urban spatial structure for realizing Giga-solar city

本研究评估太阳能光伏发电系统安装在郊区独立住宅的实质节能效果。考虑了不同居住区的居住能耗和交通能耗的差异。因此，城市郊区的建设将有效地减少经常使用汽车的家庭的能源消耗，本研究评估了298个配电变电站由于PVS的高穿透率而引起的电压升高的年度最大和年度剩余电力供应总量在爱知县的供应区。因此，在电力需求大的住宅和商业建筑物的复杂区域中增加PVS容量对于减轻对电力系统的影响是有效的。

This study evaluated the substantial energy conservation effect of photovoltaic power generation system (PVS) installed in suburban detached-houses. The difference in both the residential and transport energy consumption by inhabitation area was taken into account. As a result, construction of clustered sub-urban area would be effective for reducing the energy consumption in the household of frequent vehicle utilization, resulting in the practical energy conservation of PVS installation for the household with large family member.This study evaluated the annual maximum and annual total of surplus electricity supply as a measure of voltage rise due to the high penetration of PVS in 298 distribution substation supply areas in Aichi Prefecture. As a result, the increase of PVS capacity in an complex area of residences and commercial buildings with large electricity demand is effective for mitigating the impact on the electric power system.
