Description
図3は、発電装置選択部242における発電装置選択処理のフローチャートを示す図である。
例えば図5の場合には、太陽光発電装置11を稼動させる条件は、符号51で示すように、天気状況が晴れの時間帯である。風力発電装置12を稼動させる条件は、符号52で示すように、風速が8m/s以上のときである。水力発電装置13を稼動させる条件は、符号53で示すように、天気状況が雨、降水確率が50%以上、降水量が0mmより大きいことを満たすときである。条件を満たせば複数の発電装置を稼動させてもよく、図の例では、風力発電装置12と水力発電装置13とを同時に稼動させている。
図8は、発電電力量と消費電力量の時間推移の一例を示す図である。発電電力量データベース252(図6)と消費電力量データベース253(図7)を参照し、過去の所定期間(例えば1ヶ月程度あれば、安定した電力状況を把握できる)の総発電量と総消費量の平均値を求めて、一日の各時間帯の推移としてプロットしたものである。(a)は一日の各時間帯の総発電量P0と総消費量Q0の推移を示し、(b)は時間帯Aを拡大し、(c)は時間帯Bを拡大したものである。(b)と(c)では、現在の総発電量Pと総消費量Qも合わせてプロットしている。
図9は、各電気機器の消費電力量の時間推移の一例を示す図である。消費電力量データベース253(図7)を参照し、過去の所定期間(例えば1ヶ月程度)の電気機器ごとの消費量の平均値を求めて、一日の各時間帯の推移としてプロットしたものである。(a)は一日の各時間帯の各機器の消費量Rの推移を示し、(b)は時間帯Bを拡大したものである。電気機器のうち外灯31(消費量R1)は夜間と早朝のみ点灯しており、補助灯32(消費量R2)は常時点灯している。
