As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
The terms "comprises" and "comprising" indicate the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The term "and/or" refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
Referring to fig. 1, a power control method of a power generation system of a methanol reforming fuel cell according to an embodiment of the invention is provided. As shown in fig. 1, the power control method of the methanol reforming fuel cell power generation system includes steps S10 to S20. The method comprises the following steps:
s10, monitoring the working state of the storage battery, and acquiring the SOC of the storage battery;
s20, judging whether the SOC meets a first preset condition or not; and when the SOC does not meet the first preset condition, performing nonlinear regulation on the preset power of the fuel cell and performing smooth regulation on the fuel.
In this embodiment, the first preset condition is:
SOCmin<SOC<SOCmax；
wherein, SOC is the charge state of the fuel cell and represents the percentage of the remaining available electric quantity of the cell to the total capacity; SOCmin, SOCmax represent the minimum and maximum values of the remaining usable power of the fuel cell as a percentage of the total capacity, respectively.
After the SOC of the storage battery is obtained, judging whether the storage battery meets SOCmin < SOC < SOCmax, and when the storage battery does not meet SOCmin < SOC < SOCmax, linear adjustment of preset power of the fuel cell is needed, and smooth adjustment of fuel is needed to keep stability of the system.
Referring to fig. 2, fig. 2 provides an overall flow of a method for controlling power in a methanol reforming fuel cell power generation system. In one embodiment, the linear adjustment of the preset power of the fuel cell and the smooth adjustment of the fuel involve 2 cases, as shown in fig. 2:
1) When SOC is<SOCmin, and I<I float When the fuel cell is started, the preset power of the fuel cell is gradually increased, and the fuel is smoothly increased and regulated; wherein I represents the charge/discharge current of the storage battery, I float Representing the current ground floating set value;
2) When SOC > SOCmax, and I > -I float And gradually reducing the preset power of the fuel cell, and performing smooth reduction adjustment on the fuel.
When the charge/discharge current exceeds the set threshold and reaches the set duration, the power control in the normal SOC stage adjusts the preset power of the fuel cell according to the power linear adjustment table. Specifically, preset power = current power + battery charge/discharge current × battery voltage:
P set ＝P now +I*V out ；
further, the power control in the SOCmin < SOC < SOCmax period is performed by gradually increasing/decreasing the power of the fuel cell to a preset power until the battery approaches the float state. Specifically, preset power = current power + power preset step value:
P set ＝P now +P step ；
it should be emphasized that here approaching the float state is to avoid the battery being in the float state, i.e. the current I during charging>Float charging set value I float The method comprises the steps of carrying out a first treatment on the surface of the Current I during discharge<Negative float setting-I float . According to the embodiment, the storage battery can be prevented from being in a floating charge state through accurate control of charge/discharge current, so that the stability of the power of the fuel cell is enhanced, and the stability of a system is improved.
As shown in fig. 2, in one embodiment, the power control method of the power generation system of the methanol reforming fuel cell further includes:
when the SOC meets a first preset condition, acquiring the working current of the storage battery;
judging whether the working current meets a second preset condition or not; and when the working current does not meet the second preset condition, utilizing a linear regulation meter to carry out linear regulation on the preset power of the fuel cell and smooth regulation on the fuel.
In this embodiment, when the SOC of the storage battery satisfies the first preset condition, the working current of the storage battery is obtained to determine the relationship between the working current and the second preset condition, where the working current of the storage battery mainly refers to the charging current or the discharging current, and when the working current satisfies the second preset condition, the stable operation of the system can be ensured by keeping the preset power of the fuel cell unchanged. When the working current does not meet the second preset condition, the preset power of the fuel cell is linearly regulated and the fuel is smoothly regulated by utilizing a linear regulation meter so as to ensure the stability of the system.
Specifically, the second preset condition in the present embodiment is:
I f_set <I<I c_set ；
wherein I represents the charge/discharge current of the storage battery, I f_set Indicating the set value of discharge current, I c_set Indicating the charging current set point.
In an exemplary embodiment, when the operating current does not meet the second preset condition, the preset power of the fuel cell is linearly adjusted and the fuel is smoothly adjusted by using the linear adjustment table, including 2 cases, as shown in fig. 2:
3) When I > I c_set And T is c ＞T c_set Gradually increasing the preset power of the fuel cell according to the linear regulation table and smoothly increasing and regulating the fuel, wherein T is c Indicating the charging time T c_set Indicating the charging time set point.
4) When I<I f_set And T is f ＞T f_set Gradually increasing the preset power of the fuel cell according to the linear regulation table and smoothly increasing and regulating the fuel, wherein T is f Indicating discharge time, T f_set Indicating the discharge time set point.
5) When I > I c_set And T is c ≤T c_set When or when I<I f_set And T is f ≤T f_set And when the preset power of the fuel cell is kept unchanged.
Unlike the cases 1) and 2) of the above embodiment, in this embodiment, whether the charging current of the storage battery is greater than the charging current set value and the charging time reaches the corresponding set value, or whether the charging current of the storage battery is smaller than the discharging current set value and the discharging time reaches the corresponding set value, the preset power of the fuel cell is gradually increased according to the linear adjustment table, and then the fuel is smoothly increased and adjusted, and in operation, the charging/discharging current of the storage battery is monitored in real time until the second preset condition is satisfied, the adjustment is ended, and the preset power of the fuel cell is kept unchanged.
In summary, the embodiment of the invention introduces a preset concept by tracking the load power and the state of the storage battery and considering the instability caused by the reaction lag of the reforming part when the power adjustment is performed. Since the change in load power and battery state affects the change in preset value, but the preset value does not directly affect the fuel cell power, the preset power can be gradually reached by smoothly adjusting the reactor fuel. In the embodiment, the SOC and the charge/discharge current of the storage battery are monitored, the relation between the SOC and the charge/discharge current of the storage battery and the preset condition is judged, and when the preset condition is not met, the fuel is smoothly regulated, so that the preset power is finally achieved. Therefore, the embodiment can respond to the change of the load power and ensure the stability of the system.
The power control method of the methanol reforming fuel cell power generation system provided by the embodiment can be used for both a direct current power generation system and an alternating current power generation system. Fig. 3-4 are schematic diagrams of the method applied to a direct current power generation system and an alternating current power generation system respectively. As can be seen from fig. 3, when the control method is applied, the monitoring unit is controlled to control the hydrogen output by controlling the fuel supply module and the methanol reforming hydrogen production system, the hydrogen output enters the fuel cell power generation module 4 to generate electric energy through electrochemical reaction, the DC/DC converter 5 converts the voltage of the fuel cell to meet the direct-current voltage requirement of the user, and the DC/DC converter 5 controls the voltage and the current to control the power of the fuel cell. The output contactor controls the DC/DC output, i.e., whether the fuel cell power generation system is providing power to the consumer load. As can be seen from fig. 4, when the control method is applied, the monitoring unit is controlled to control the hydrogen output by controlling the fuel supply module and the methanol reforming hydrogen production system, the hydrogen output enters the fuel cell power generation module 4 to generate electric energy through electrochemical reaction, the DC/DC converter 5 converts the voltage of the fuel cell to meet the direct-current voltage requirement of the user, and the DC/DC converter 5 controls the voltage and the current to control the power of the fuel cell. The output contactor 1 controls the connection between the DC/DC converter and the DC/AC, and the output contactor 2 controls the connection between the DC/AC converter and the load of the user, i.e. controls whether the AC power is supplied to the user.
Therefore, the method provided by the embodiment can be used for a direct current power generation system and is also suitable for an alternating current power generation system, and the application range is wide.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
