自給自足住宅の多面的評価

―PV・蓄電池の大容量化や運用高度化ポテンシャルの分析―

抄録

This study evaluates the economic and environmental performance of several households with different PV power generation and power demand characteristics. The analysis was multidimensional, ranging from no PV and no battery energy storages to the installation of each device, further capacity expansion, and advanced control potential of battery energy storages. When evaluating the potential for advanced operation of battery energy storages, three different foresight periods; one day, two days, and one year are compared in the optimization calculation. The results demonstrate that 2-day planned operation yielded almost the same operational patterns and effects as those obtained with 1-year planned operation.
