Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by persons of ordinary skill in the art without making any inventive effort based on the embodiments of the present invention are within the scope of protection of the present invention.
In the related technology, most of large-scale renewable energy hydrogen production projects still depend on the regulating function of a large power grid, in order to improve the utilization rate of hydrogen production equipment, an electrolytic tank is always kept in a full-load operation mode, but the operation mode does not exert the advantages of a hydrogen production unit as a variable load and participating in stabilizing the fluctuation of a power supply, does not play a role in assisting a photovoltaic power supply to be integrated into an energy system on a large scale, and brings new pressure to the peak regulation capacity of the power grid, so that more traditional generating sets such as thermal power plants are required to realize power balance.
In order to promote the further development of large-scale renewable energy hydrogen production projects, a more positive control strategy must be adopted for the hydrogen production system, so that the hydrogen production load is regulated in real time along with the power generation, and the hydrogen production system load can be greatly increased or reduced in minutes or even shorter time, which presents challenges for regulating the hydrogen production system, wherein the electrolytic tank has certain load regulating capability, but the regulating speed of the electrolytic tank needs to be limited in consideration of the stable operation of the whole hydrogen production process system, and secondly, the working load range of the alkaline electrolytic tank is generally maintained between 30% and 100% for safety reasons.
In order to solve the technical problems, the inventor creatively thinks that the power of photovoltaic power generation is measured in real time by utilizing the power generation power measuring unit, then the power generation power transmitted by the power generation power measuring unit and the operation parameter information transmitted by the electrolytic cells are collected by utilizing the controller, and after analysis, a load regulation strategy of each electrolytic cell is formulated and transmitted to the electrolytic cells for execution.
Referring to fig. 1, an embodiment of the present invention provides a load adjustment method for electrolytic hydrogen production, which is applied to a controller of an electrolytic hydrogen production system, the electrolytic hydrogen production system including a renewable energy power generation device, a generated power measurement device, and a plurality of electrolytic cells, the renewable energy power generation device being connected to the generated power measurement device and all the electrolytic cells, respectively, and all the electrolytic cells and the generated power measurement device being connected to the controller, respectively, the method comprising:
step 100, acquiring the operation parameters of each electrolytic tank in the current state and the generated power of the renewable energy power generation device in the current state, which is measured by the generated power measurement device;
Step 102, determining a target regulating power of each electrolytic cell based on the generated power and the operation parameters, so as to utilize the target regulating power to carry out power regulation on each corresponding electrolytic cell.
In this embodiment, firstly, an operation parameter of each electrolytic cell in a current state and a generated power of the renewable energy power generation device in the current state measured by the generated power measurement device are obtained, then, a target adjustment power of each electrolytic cell is determined based on the generated power and the operation parameter, and finally, power adjustment is performed on each corresponding electrolytic cell by using the target adjustment power. Therefore, the load of the electrolytic tank can be adjusted in real time along with the generated power by the scheme.

In the embodiment, the target regulating power of each electrolytic tank can be better determined by utilizing at least one of the maximum load regulating amplitude, the optimal energy efficiency power and the maximum power and the generated power, and meanwhile, the advantage that the hydrogen production equipment participates in stabilizing the power supply fluctuation as a variable load can be better exerted.
In one embodiment of the present invention, the step of "determining a load adjustment mode of each electrolytic cell based on the generated power and the operating power" includes:
calculating the total power difference between the generated power and the sum of the running power of each electrolytic cell;
If the total power difference is positive, determining the load adjusting mode of each electrolytic tank as load improvement;
if the total power difference is negative, the load regulation mode of each electrolytic cell is determined as load reduction.
In the embodiment, the load regulation mode of each electrolytic cell is determined by calculating the total power difference value of the sum of the generated power and the running power of each electrolytic cell, so that each electrolytic cell realizes 'load follow-up source movement', meanwhile, the dependence on a large power grid is reduced, and the utilization rate of hydrogen production equipment is improved.
In one embodiment of the present invention, when the load adjustment mode is to increase the load, the step of "determining the target adjustment power for each electrolytic cell based on the generated power and at least one of the maximum load adjustment amplitude, the optimal energy efficiency power, and the maximum power" includes:
screening out a target electrolytic tank with the running power smaller than the optimal energy efficiency power;
sequencing the difference value of the optimal energy efficiency power and the running power of each target electrolytic cell in descending order to obtain a first distribution set;
Sequentially distributing the total power difference to each target electrolytic cell according to the sequence of a first distribution set and a preset first distribution principle so that each target electrolytic cell operates according to the distributed power, wherein the first distribution principle simultaneously satisfies the following two conditions that the distributed power of each target electrolytic cell is not more than the optimal energy efficiency power, and the difference between the distributed power of each target electrolytic cell and the power before distribution is not more than the maximum load adjustment amplitude;
if the total power difference is completely distributed in the first distribution set, determining the distributed power of each target electrolytic cell as target regulating power;
if the total power difference is not fully allocated in the first allocation set, performing:
Sequencing the current running power of all the electrolytic cells according to ascending order to obtain a second distribution set;
Distributing the residual total power difference which is not completely distributed in the first distribution set to each electrolytic tank successively according to the sequence of the second distribution set and a preset second distribution principle, wherein the second distribution principle simultaneously satisfies the following two conditions that the power distributed by each electrolytic tank is not more than the maximum power, and the difference between the power finally distributed by each electrolytic tank and the power before the first distribution is not more than the maximum load regulating amplitude;
the final allocated power of each electrolytic cell is determined as target regulated power.
In the embodiment, by the method, each electrolytic tank can adjust the work load in real time, and meanwhile, each electrolytic tank is controlled to operate towards the optimal energy efficiency power, so that the operation stability of the hydrogen production equipment is improved.
In some embodiments, the method for adjusting the load in a load reducing manner is easily obtained by referring to the above method, and will not be described herein.
Therefore, according to the method provided by the embodiment, the regulation command is ensured not to exceed the regulation capability of the electrolytic tank hardware equipment, the regulation rate is limited in the allowable range, the 'load follow-up source movement' of the hydrogen production system is realized, the electric power is consistent with the generated power, and the target regulation power of each electrolytic tank can be dynamically close to the respective optimal energy efficiency power on the premise that the target regulation power of each electrolytic tank is consistent with the generated power, so that the maximum hydrogen production amount is realized.
