As shown, the management device 110 includes a power converter 202 and an energy manager 204. The power converter 202 converts the received power and outputs the corresponding power according to the control signals S C1 to S C4 .

In other embodiments, the energy manager 204 generates control signals S C1 ~S C4 based on the detection signal S DT . In a possible embodiment, the detection signal S DT represents the state of the rechargeable battery device 104, such as the amount of charge, current, voltage, and/or temperature.
第3圖為本創作管理裝置110的一可能動作示意圖。如圖所示,當充電電池裝置104的充電容量SOC小於容量值VA1 時,管理裝置110根據再生能源裝置(此處以太陽能發電系統為例)所產生的再生電力PRN ,產生充電電力PCH 。FIG. 3 is a schematic diagram of a possible action of the authoring management device 110. As shown in the figure, when the charge capacity SOC of the rechargeable battery device 104 is less than the capacity value VA 1 , the management device 110 generates the charging power P CH according to the regenerative power P RN generated by the regenerative energy device (here, a solar power generation system is taken as an example). .
舉例而言,在晴天或是多雲時,太陽能發電系統所產生的再生電力足以對電池充電。因此,管理裝置110轉換 太陽能發電系統所產生的再生電力PRN ,用以產生充電電力PCH 。然而,在夜間時,太陽能發電系統的發電能力較為薄弱,故管理裝置110不轉換再生電力PRN 。在一可能實施例中,管理裝置110停止產生充電電力PCH 。在另一可能實施例中,管理裝置110轉換市電PAC ,用以產生充電電力PCH 。For example, on sunny or cloudy days, the regenerative power generated by the solar power system is sufficient to charge the battery. Therefore, the management device 110 converts the regenerative electric power P RN generated by the solar power generation system to generate the charging electric power P CH . However, at night, the power generation capability of the solar power generation system is weak, so the management device 110 does not convert the regenerative power P RN . In a possible embodiment, the management device 110 stops generating the charging power P CH . In another possible embodiment, the management device 110 converts the mains P AC to generate the charging power P CH .
在其它實施例中,管理裝置110具有一計時器(未顯示),用以判斷目前的時間係為電費高價或低價時段。當再生電力PRN 小於一再生臨界值時,管理裝置110根據計時器的計數值,用以在電費低價時段,轉換市電PAC ,產生該充電電力。在另一可能實施例中,若處於電費高價時段,管理裝置110不提供充電電力PCH 。In other embodiments, the management device 110 has a timer (not shown) for determining that the current time is a high or low price of electricity. When the regenerative power P RN is less than a regeneration threshold, the management device 110 is configured to convert the mains P AC to generate the charging power according to the count value of the timer. In another possible embodiment, the management device 110 does not provide the charging power P CH if it is in the high electricity price period.
當充電電池裝置104的充電容量SOC大於容量值VA1 但小於容量值VA2 時,管理裝置110根據太陽能發電系統所產生的再生電力PRN 以及負載112的使用狀態,產生充電電力PCH 及輔助電力PAX 之至少一者。When the charging capacity SOC of the rechargeable battery device 104 is greater than the capacity value VA 1 but smaller than the capacity value VA 2 , the management device 110 generates the charging power P CH and the auxiliary according to the state of use of the regenerative power P RN and the load 112 generated by the solar power generation system. At least one of the power P AX .
舉例而言,在晴天時,太陽能發電系統處於發電高峰。當再生電力PRN 足以應付負載112所需的電力時,管理裝置110轉換再生電力PRN ,用以產生輔助電力PAX 與充電電力PCH 。當再生電力PRN 約略等於負載112所需的電力,則管理裝置110僅僅產生輔助電力PAX ,而不對充電電池裝置104充電。在此例中,由於不需轉換再生電力PRN 以產生充電電力PCH ,也不需轉換充電電力PCH 以產生輔助電力,故可減少兩次的電力轉換,以避免不必要的能量損耗。For example, on a sunny day, the solar power system is at a peak in power generation. When the regenerative power P RN is sufficient to cope with the power required by the load 112, the management device 110 converts the regenerative power P RN to generate the auxiliary power P AX and the charging power P CH . When the regenerative power P RN is approximately equal to the power required by the load 112, the management device 110 generates only the auxiliary power P AX without charging the rechargeable battery device 104. In this embodiment, since the regenerative power P RN without conversion to generate a charging power P CH, also charging power P CH without conversion to generate auxiliary power, it can reduce the power converter twice, to avoid unnecessary energy loss.
在多雲時,太陽能發電系統產生的再生電力PRN 較 低,因此,管理裝置110轉換再生電力PRN ,用以產生充電電力PCH 。此時,若負載112為重載時,則管理裝置110可擷取充電電池裝置104的電力,用以得到放電電力PDCH ,並轉換放電電力PDCH ,產生輔助電力PAX 予微電網108。在其它實施例中,管理裝置110不擷取充電電池裝置104的電力,而轉換再生電力PRN ,用以產生輔助電力PAX 。When it is cloudy, the regenerative power P RN generated by the solar power generation system is low, and therefore, the management device 110 converts the regenerative electric power P RN to generate the charging electric power P CH . At this time, if the load 112 is a heavy load, the management device 110 can extract the power of the rechargeable battery device 104 to obtain the discharged power P DCH , and convert the discharged power P DCH to generate the auxiliary power P AX to the micro grid 108 . In other embodiments, the management device 110 does not draw power from the rechargeable battery device 104, but converts the regenerative power P RN to generate the auxiliary power P AX .
在夜間時,太陽能發電系統的發電能力薄弱,故管理裝置110擷取充電電池裝置104的電力,用以得到放電電力PDCH ,並轉換放電電力PDCH ,用以產生輔助電力PAX 予微電網108。在其它實施例中,管理裝置110可在電費低價時段,擷取並轉換市電PAC ,用以產生充電電力PCH 。At night, the power generation capability of the solar power generation system is weak, so the management device 110 draws the power of the rechargeable battery device 104 to obtain the discharge power P DCH and converts the discharge power P DCH for generating the auxiliary power P AX to the micro grid. 108. In other embodiments, the management device 110 may retrieve and convert the commercial power P AC for generating the charging power P CH during the low-cost electricity period.
當充電電池裝置104的充電容量SOC大於容量值VA2 時,管理裝置110根據太陽能發電系統所產生的再生電力PRN ,產生輔助電力PAX 。舉例而言,在晴天及多雲時,管理裝置110轉換再生電力PRN ,用以產生輔助電力PAX 。在夜間時,太陽能發電系統的發電能力薄弱並且充電電池裝置104的電量足夠,故管理裝置110不產生充電電力PCH 。在一可能實施例中,管理裝置110擷取充電電池裝置104的放電電力PDCH ,並轉換放電電力PDCH ,用以產生輔助電力PAX ,以降低市電的需求。When the charge capacity SOC of the rechargeable battery device 104 is greater than the capacity value V A2 , the management device 110 generates the auxiliary power P AX based on the regenerative power P RN generated by the solar power generation system. For example, on sunny days and cloudy days, the management device 110 converts the regenerative power P RN to generate the auxiliary power P AX . At night, the power generation capability of the solar power generation system is weak and the amount of charge of the rechargeable battery device 104 is sufficient, so the management device 110 does not generate the charging power P CH . In a possible embodiment, the management device 110 captures the discharged power P DCH of the rechargeable battery device 104 and converts the discharged power P DCH to generate the auxiliary power P AX to reduce the demand of the commercial power.
第4圖為本創作管理裝置110的另一可能動作原理。在本實施例中,當再生能源裝置102非發電高峰時,管理裝置110根據負載的使用狀況,進行電力流向調整。舉例而言,當負載112為輕載(即驅動電力PDR 小於一預設值)時,則管理裝置110停止提供充電電力PCH 。即使充電電池裝置104具有足夠電 力,管理裝置110也不擷取充電電池裝置104的電力。在一可能實施例中,管理裝置110僅僅轉換再生電力PRN ,用以產生輔助電力PAX 。此時,再生電力並聯市電,與市電同步供電予負載112。在其它實施例中,管理裝置110不轉換再生電力PRN 。FIG. 4 is another possible operational principle of the authoring management apparatus 110. In the present embodiment, when the regenerative energy device 102 is not generating a peak, the management device 110 performs the power flow direction adjustment according to the usage state of the load. For example, when the load 112 is lightly loaded (ie, the driving power P DR is less than a predetermined value), the management device 110 stops providing the charging power P CH . Even if the rechargeable battery device 104 has sufficient power, the management device 110 does not draw power from the rechargeable battery device 104. In a possible embodiment, the management device 110 only converts the regenerative power P RN for generating the auxiliary power P AX . At this time, the regenerative power is connected in parallel with the mains, and is supplied to the load 112 in synchronization with the commercial power. In other embodiments, the management device 110 does not convert the regenerative power P RN .
當負載112為重載(即驅動電力PDR 大於預設值)時,則管理裝置110擷取充電電池裝置104的電力,並轉換放電電力PDCH ,用以產生輔助電力PAX 。在此例中,將電池的電力透過市電併網型逆變器輸出至微電網,並聯市電後與市電同步供電予負載112使用。When the load 112 is heavy (ie, the driving power P DR is greater than a preset value), the management device 110 captures the power of the rechargeable battery device 104 and converts the discharged power P DCH to generate the auxiliary power P AX . In this example, the power of the battery is output to the microgrid through the mains grid-connected inverter, and the parallel power is supplied to the load 112 in synchronization with the commercial power.
在其它實施例中,管理裝置110係根據市電PAC 的狀況,決定電力的分配。舉例而言,當市電斷電時,管理裝置110啟動獨立供電模式。在獨立供電模式下,由再生能源裝置102及/或充電電池裝置104提供電力作為備援電力。在一可能實施例中,管理裝置110轉換再生電力PRN 及/或放電電力PDCH ,用以產生驅動電力PUD 予負載114。在另一可能實施例中,當充電電池裝置104的充電電量SOC低於20%時,管理裝置110僅轉換再生電力PRN 。In other embodiments, the management device 110 determines the allocation of power based on the status of the mains P AC . For example, when the utility power is lost, the management device 110 initiates an independent power supply mode. In the independent power supply mode, power is supplied by the regenerative energy device 102 and/or the rechargeable battery device 104 as backup power. In a possible embodiment, the management device 110 converts the regenerative power P RN and/or the discharged power P DCH to generate the driving power P UD to the load 114. In another possible embodiment, when the charging power SOC of the rechargeable battery device 104 is lower than 20%, the management device 110 converts only the regenerative electric power P RN .
由於管理裝置係根據外部再生能源充足與否作為儲能管理的依據,故可達到主動式管理儲能的功能。當再生能源充足時,儲存多餘的再生能源,以增加再生能源的使用效率。另外,管理裝置根據再生能源的發電量,充電電池的狀態、負載的用電量以及市電狀態,進行能量調度,因而降低用電成本並可適當地提供緊急電力。Since the management device is based on the availability of external renewable energy as the basis for energy storage management, the function of actively managing energy storage can be achieved. When the renewable energy is sufficient, the surplus renewable energy is stored to increase the efficiency of the use of renewable energy. Further, the management device performs energy scheduling based on the amount of power generation of the regenerative energy, the state of the rechargeable battery, the amount of power used by the load, and the state of the commercial power, thereby reducing the cost of power consumption and providing emergency power appropriately.
