The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
With the diversification of energy supply requirements, hydrogen energy, photovoltaic solar energy, wind energy and the like are used as clean energy and are applied to daily life of people more and more widely. Energy storage control using wind power generation or photovoltaic power generation is popular, but the method for controlling energy storage and power generation of a power system based on wind power generation or photovoltaic power generation cannot maintain a stable power supply state for a long time.
In view of this, the hydrogen energy can support the stable operation of a high-proportion new energy power grid due to the characteristics of high energy density, low carbon, environmental protection and suitability for long-term storage.
Therefore, the embodiment of the present invention discloses a control method for hydrogen energy storage, which can be used in a hydrogen storage control system, where the hydrogen storage control system may include a hydrogen storage controller and a hydrogen-electricity conversion controller, as shown in fig. 1, and includes the following steps:
step S11: and receiving a power control instruction value sent by the server.
In fig. 1, it is first checked whether or not the power control command value issued by the server is received, and if not, the following step S15 is executed, if step S11 is executed.
Specifically, the server can be used as a server side of upper-layer scheduling control to establish remote communication with the hydrogen storage control system. The server is configured to issue a power control instruction value to the hydrogen storage control system in this embodiment, where the power control instruction value is used to perform power control of three different stages on the hydrogen storage control system. The three different phases of control include: a hydrogen storage minimum standby control phase, a normal operation control phase and a hydrogen storage limiting control phase.
For example: let the power control command value be Pt, Pt may be equal to 0, Pt may be greater than 0, and Pt may also be less than 0. When Pt is 0, the server may not issue the power control instruction value to the hydrogen storage control system, and at this time, the hydrogen storage control system is not controlled by the server, and may execute the operation control instruction according to the own control instruction.
Step S12: determining a hydrogen storage volume range value to which the current volume value of the hydrogen belongs, wherein the hydrogen storage volume range value comprises: a first hydrogen storage range value, a second hydrogen storage range value, and a third hydrogen storage range value.
As shown in FIG. 2, the values of the hydrogen storage volume range include three different intervals. Wherein, the first interval value is a first hydrogen storage range value, and the hydrogen amount V can be considered to satisfy that VLL is more than V and less than or equal to VL and is taken as a minimum standby interval; the second interval value is a second hydrogen storage range value, and the hydrogen amount V can be considered to meet the condition that VL is more than V and is less than or equal to VH, and is taken as a normal operation interval; the third interval value is a third hydrogen storage range value, and the hydrogen amount can be considered to satisfy that VH is more than V and is less than or equal to VHH, which is taken as a limited storage interval. The hydrogen energy storage and generation control method in the embodiment executes the corresponding control means through the three different intervals to actively adjust the hydrogen storage capacity and timely consume the electric energy, so that the problems of continuous power supply and timely consumption of the electric energy can be guaranteed.
The current volume value of the hydrogen is the current hydrogen amount V, and further, the first interval value, the second interval value or the third interval value is determined according to the specific value of V.
Step S13: and acquiring the current electrolysis power value for hydrogen production and the current power supply output power value for hydrogen-electricity conversion.
The current electrolysis power value for hydrogen production and the current power output power value for hydrogen-electricity conversion can be obtained by real-time monitoring through a data monitoring device, and the data monitoring device can be a power sensor.
Step S14: controlling the current electrolysis power value and the current power supply output power value to meet a target preset condition according to the hydrogen storage volume range value to which the power control instruction value and the current volume value belong, so that the current volume value belongs to a second hydrogen storage range value, wherein the target preset condition comprises the following steps: the method comprises the steps of a first preset condition, a second preset condition and a third preset condition.
The second hydrogen storage range value can guarantee normal operation of the hydrogen storage process, under the control of the power control instruction value, the current electrolysis power value and the current power output power value meet the target preset condition, and then the current volume value belonging to the first hydrogen storage range value or the third hydrogen storage range value belongs to the second hydrogen storage range value, so that the current hydrogen storage volume is guaranteed to enter a normal operation interval, and the purposes of normal electric energy consumption and normal timely normal power generation are further guaranteed.
In an embodiment, in the method for controlling hydrogen energy storage and generation according to an embodiment of the present invention, the step S14 of controlling the current electrolysis power value and the current power output power value to satisfy the target preset condition so that the current volume value belongs to the second hydrogen storage range value further includes:
if the current volume value belongs to the first hydrogen storage range value, adopting the first preset control condition as follows:
Pt＞0： Pe＝Pt， Pc＝0；
Pt＜0： Pc＝|Pt|， Pe＝0；
Pt＝0： Pe＝Pe_max， Pc＝0；
wherein Pt is a power control instruction value, Pe is a current electrolysis power value, Pc is a current power supply output power value, and Pe _ max is a maximum electrolysis power value.
For example: in FIG. 2, the current hydrogen amount is in the interval of VLL < V < VL, i.e. the first hydrogen storage range, i.e. the minimum backup interval. In the interval, the control operation is as follows, and the current hydrogen amount is returned to the normal interval by adjusting the current electrolysis power value and the current power supply output power value, so as to ensure the sufficient standby margin.
When Pt is more than 0, the condition that the output of a wind power supply is more than the load requirement and the hydrogen production and storage requirements of electrolysis exist can be implied; when Pt is less than 0, the negative demand power can be represented, and the power generation demand of the fuel cell for hydrogen-electricity conversion exists; pt-0 may mean an unscheduled power control instruction.
When Pt is more than 0: pe ═ Pt, Pc ═ 0; at the moment, the demand of hydrogen production and storage exists, the current electrolysis power value Pe is equal to the rate control instruction value Pt, and Pc is 0, which means that hydrogen production and storage can be continued, and hydrogen production control needs to be continuously executed under the remote control of the server without executing hydrogen-electricity conversion control.
Pt is less than 0: pc ═ Pt |, Pe ═ 0; at this time, there is a power generation demand for hydrogen-electricity conversion by the fuel cell, and the absolute value of the current power supply output power value Pc is equal to the absolute value of the power control command value Pt, and a value of Pe equal to 0 also means that the amount of hydrogen gas is still sufficient, and hydrogen production control does not need to be executed.
Pt is 0: pe — max, Pc — 0; at the moment, the server does not carry out remote control, the power generation requirement of hydrogen-electricity conversion by the fuel cell does not exist, self-running control can be executed, the current electrolysis power value Pe and the maximum electrolysis power value Pe _ max can also continuously store hydrogen, and therefore hydrogen production control is continuously executed, and sufficient standby margin is ensured.
In another embodiment, the step S14 of controlling the current electrolysis power value and the current power output power value to satisfy the target preset condition so that the current volume value belongs to the second hydrogen storage range value further includes:
if the current volume value belongs to the second hydrogen storage range value, adopting the second preset control condition as follows:
Pt＞0： Pe_＝Pt；
Pt＜0： Pc＝|Pt|；
wherein Pt is a power control instruction value, Pe is a current electrolysis power value, and Pc is a current power supply output power value.
For example: in FIG. 2, the current hydrogen amount is in the range of VL < V.ltoreq.VH, i.e. belongs to the second hydrogen storage range, i.e. the normal operation range. In this interval, the control operation is as follows.
Pt is more than 0: pe _ ═ Pt; at the moment, Pt is not equal to 0, the hydrogen production and storage requirements of electrolysis exist, the current electrolysis power value Pe is equal to the power control instruction value Pt, and the hydrogen production can be continuously performed, and the hydrogen production control needs to be continuously executed under the remote control of a server. At this time, during the production of hydrogen, hydrogen-electricity conversion power generation can be normally performed by the fuel cell stack.
Pt is less than 0: pc ═ Pt |; at this time, there is a power generation demand for hydrogen-electricity conversion by the fuel cell, and the absolute value of the current power supply output power value Pc is equal to the absolute value of the power control instruction value Pt, which means that hydrogen-electricity conversion can be continued, and hydrogen-electricity conversion control needs to be continued under remote control of the server. In this case, hydrogen can be normally produced during the hydrogen-electricity conversion power generation process by the fuel cell.
In another embodiment, the step S14 of controlling the current electrolysis power value and the current power output power value to satisfy the target preset condition so that the current volume value belongs to the second hydrogen storage range value further includes:
if the current volume value belongs to a third hydrogen storage range value, adopting a third preset control condition as follows:
Pt＞0： Pe＝Pt， Pc＝Pc_max；
Pt≤0： Pe＝0， Pc＝Pc_max；
wherein, Pt is a power control instruction value, Pe is a current electrolysis power value, Pc is a current power supply output power value, and Pc _ max is a maximum power supply output power value.
For example: in FIG. 2, when the current hydrogen amount is in the interval of VH < V < VHH, i.e. belongs to the third hydrogen storage range, i.e. the limited storage interval. In this interval, the control runs as follows:
pt is more than 0: pe ═ Pt, Pc ═ Pc _ max; at this time, the hydrogen storage requirement of electrolytic hydrogen production exists, and the hydrogen storage is sufficient, so that the fuel cell stack can continuously execute hydrogen-electricity conversion, the current electrolytic power value Pe is equal to the power control instruction value Pt, and the current power supply output power value Pc is equal to the maximum power supply output power value. The hydrogen amount returns to the normal interval by adjusting the pre-electrolysis power value and the current power supply output power value, so that the sufficient absorption space is ensured:
pt is less than or equal to 0: pe ═ 0, Pc ═ Pc _ max; in this case, it means that there is a power generation demand for the fuel cell stack to perform hydrogen-electricity conversion, the current hydrogen amount is sufficient, the current power supply output power value Pc may be made equal to the maximum power supply output power value Pc _ max, a power generation operation control command may be executed to the maximum extent, and when Pt is 0, there is no remote scheduling control, and power generation control may be performed in accordance with self-operation.
In one implementation manner, in fig. 1, the method for controlling hydrogen energy storage and generation in the embodiment of the present invention further includes the following steps:
step S15: and if the server does not issue the power control instruction value and the current volume value belongs to the second hydrogen storage range value, controlling the current electrolysis power value and the current power supply output power value to be respectively equal to the preset rated power value or the user input power value matched with the current electrolysis power value and the current power supply output power value.
For example: in FIG. 2, when the current hydrogen amount V is within the second hydrogen storage range, i.e., V < VH, i.e., the normal operation interval. At this time, the power control command value Pt issued by the server is not received, that is, Pt is 0, and in this interval, the control operation is as follows: without remote control condition, the current electrolysis power value can be controlled to be equal to the matched preset rated power value or the power value input by a user through self-running control. Similarly, the matched preset power value of the current power output power value can be controlled to be equal or the power value input by the user is controlled to be equal, so that the problems of continuous power supply and timely and normal consumption of electric energy can be further solved.
According to the hydrogen energy storage and production control method in the embodiment of the invention, different control strategies are correspondingly executed respectively under the condition of the power control instruction value issued by the server according to three different hydrogen storage range values of the storage space to which the current hydrogen amount belongs, so that the current electrolysis power value and the current power supply output power value meet the target preset condition, the current electrolysis power value and the current power supply output power value can be adjusted to enable the current hydrogen amount to belong to the second hydrogen storage range value, the purpose of fully controlling hydrogen production or hydrogen-electricity conversion power generation is realized, and the effects of continuously supplying power and timely consuming electric energy can be further ensured.
