The invention relates to a power distribution system, in particular to a multi-power supply distribution system and a distribution method thereof.

As the degree of industrialization in the world is getting higher and higher, the demand for petrochemical energy is higher. However, the result of the massive use of petrochemical energy is that petrochemical energy is becoming less and less, so all sectors have begun to develop alternative energy sources, hoping to ease this. The problem of insufficient stocks caused by the massive use of petrochemical energy, including alternative energy sources include nuclear energy, solar energy, wind energy, geothermal energy, tidal energy or hydrogen energy.

With the convenience and efficiency brought about by the development of different alternative energy sources, governments have begun to encourage enterprises and homes to use different alternative energy sources, which not only reduces electricity costs but also reduces plant load. Therefore, in use, an array solar module is installed, which may include a main solar module and an auxiliary solar module.

The other source of power is the engine-driven generator or fuel cell power supply; According to the use condition, one of the power sources is used as the main output power source. For example, when the vehicle is driving at a low speed (such as a speed of less than 40km/hr), the power storage group is used as the main output power source, and when the vehicle is driving at a high speed (such as If the speed exceeds 40km/hr, the engine is used to drive the generator or the fuel cell is used as the main output power source. The power supply arrangement is very inflexible, and the power supply can be differentiated only by the use condition such as the vehicle speed. Excessive consumption due to power supply from a single power source makes power supply inefficient.

For a fuel cell, the power output of the third power storage 231 is adjusted by the third power regulator 232.

The switchboard unit 31 is used as a power source sink and is supplied to the power converter 32. The power converter 32 converts the received DC power into AC power and supplies the power load 40.

When the system is in use, mainly according to the control device 10 receiving a power value of the power load 40, querying a power distribution information corresponding to the power value from the pre-built output power reference table to allocate The first power storage source 211, the second power storage source 221, and the third power storage source 231 simultaneously supply power to the power load 40. The manner in which the output power reference table is established will be explained below.

The control device 10 sets the complex power setting value from small to large (Pdm_1 Pdm_2 Pdm_3 ... Pdm_n), wherein the power setting value can be set by a person to input by itself, or according to the minimum to maximum power consumption of the power load 40, for example, The minimum to maximum power consumption range of the electric load 40 includes 0 to 100 kW, and 20 power setting values are set every 5 kW, that is, Pdm_1=5 kW, Pdm_2=10 kW, Pdm_3=15 kW, and so on, Pdm_20=100 kW.

The control device 10 sets the power distribution of the first power storage source 211, the second power storage source 221, and the third power storage source 231 according to the power setting values, wherein the control device 10 passes through a power management line of the vehicle ( The first to third power storages 211-231 are connected to obtain state information of each power storage. First, the control device 10 sets the output power range of the first power storage 211 to be small. The plurality of complex first output power values are [Pbatt_1 Pbatt_2 Pbatt_3 ... Pbatt_n], and the second output power value is set from small to large according to an output power range of the second power storage 221 [Psc_1 Psc_2 Psc_3 ... Psc_n].

The control device 10 sequentially selects the power setting value from small to large, and sets the power distribution of the first to third power storage sources 211 to 231. First, the control device 10 selects a first power setting value Pdm_1, the control device 10, after each of the first output power values [Pbatt_1 Pbatt_2 Pbatt_3 ... Pbatt_n] is paired with all the second output power values [Psc_1 Psc_2 Psc_3 ...

The power value and the third output power value are set as the power allocation information. After the first power setting value is completed, the control device 10 sequentially calculates and sets the minimum power sum total value of the other power setting values and the corresponding power allocation information according to the above method, and correspondingly minimizes all the power setting values. The power total value and power allocation information are established as the output power reference table, that is, the power setting values [Pdm_1 Pdm_2 Pdm_3 ... Pdm_n] respectively correspond to a minimum power sum total value [J1 J2 J3 ... Jn].
