Description

Technical Field

[0002] Under the background of energy constraints, environmental pollution, etc., new energy is an important measure to improve the environment and save costs. In the future, hydrogen energy will mainly come from new energy power generation for hydrogen production (i.e., green hydrogen), and power-to-hydrogen will become an important form of new energy consumption and utilization. Especially considering the highly flexible adjustable characteristics of the power input to the power-to-hydrogen device, it is expected to become a new type of peak shaving resource for the power system.

[0003] Currently, there are few methods for evaluating the peak shaving potential of an electrolyzer participating in a power system. The current evaluation method only starts from the operating characteristics of the electrolyzer equipment itself, and uses the allowable output fluctuation range (i.e., the maximum output minus the minimum output) as the peak shaving potential, but does not fully consider the impact of its interactive operation mode with the power system on its participation in power system peak shaving, nor does it distinguish the potential of the two peak shaving conditions of upward peak shaving and downward peak shaving, resulting in inaccurate evaluation of the peak shaving potential of the electrolyzer participating in the power system in the project.

Obviously, the drawings described below are only some embodiments recorded in this specification.

[0028] In order to enable those skilled in the art of this technology to better understand the technical solutions in one or more embodiments of this specification, the following will describe the technical solutions in one or more embodiments of this specification clearly and completely in conjunction with the accompanying drawings in one or more embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this invention.

[0029] The general idea of this invention is to consider the flexible operation ability of the electrolyzer in the green hydrogen project and evaluate the capacity potential of the electrolyzer as a flexible resource to participate in the peak shaving of the power system, taking into account factors such as the operation mode of the electrolyzer, the interactive power with the power system, and the surplus new energy in the large power grid that affect the peak shaving potential.

[0030] In addition, different from general power consumption loads, the electrolyzer can operate with a highly flexible variable load according to peak shaving needs, and can even operate beyond the standard load power. Therefore, the electrolyzer as an adjustable load participating in the peak shaving of the power system can be divided into two working conditions: upward peak shaving and downward peak shaving. Among them, downward peak shaving refers to reducing the load of the electrolyzer and decreasing the load demand for the power system, so as to relieve the power supply guarantee pressure of the power system during the period of tight power supply and demand in the power system. Its peak shaving potential is the maximum range that the electrolyzer can allow to reduce the power received from the power system at each moment. Upward peak shaving refers to increasing the load of the electrolyzer and increasing the load demand for the power system, so as to assist the power system in absorbing surplus new energy during the period of loose power supply and demand in the power system and large-scale generation of new energy that is difficult to absorb. Its peak shaving potential is the maximum range that the electrolyzer can allow to increase the power received from the power system and can effectively absorb the surplus new energy in the power system at each moment. Based on the above peak shaving principle, the following will make a detailed description of this invention in conjunction with the specific implementation manners and the accompanying drawings of the specification.

[0031] Method embodiments

[0032] According to an embodiment of the present invention, there is provided a method for evaluating the peak shaving potential of an electrolyzer in a green hydrogen project, as follows Figure 1 shown is a flowchart of the method for evaluating the peak shaving potential of an electrolyzer in a green hydrogen project provided in this embodiment. According to the method for evaluating the peak shaving potential of an electrolyzer in a green hydrogen project of an embodiment of the present invention, the method includes the steps:

[0033] Step S1: According to the self-built new energy output power and the electrolyzer operating power in a green hydrogen project in multiple historical cycles, respectively determine the typical self-built new energy output power E t and the typical electrolyzer operating power H t .

[0034] In this embodiment, the calculation formula for the typical self-built new energy output power in a green hydrogen project at each moment is as follows:

[0035]

[0036] In the formula, E n,t is the self-built new energy output power in a green hydrogen project at the t-th moment in the n-th scheduling cycle of history, and N is the number of statistical scheduling cycles; the scheduling cycle can be set according to the actual operation, and may be one day or one week in actual operation.

[0037] The calculation formula for the typical electrolyzer operating power in a green hydrogen project at each moment is as follows:

[0038]

[0039] In the formula, H n,t is the electrolyzer operating power at the t-th moment in the n-th scheduling cycle of history, and N is the number of statistical scheduling cycles.

[0040] Step S2: Determine the power G t received by the electrolyzer from the power system at each moment according to the difference between the typical electrolyzer operating power E t and the typical new energy output power H t .

[0041] In this embodiment, in step S2, since a part of the power used by the electrolyzer comes from the self-built new energy output and a part comes from the power received from the external power system, the power received by the electrolyzer from the power system can be calculated by taking the difference between the calculation results of formula (1) and formula (2), and the following calculation formula is as follows:

[0042] G t = H t - E t (3).

[0043] Step S3: Based on the minimum operating power of the electrolyzer system, calculate and determine the minimum operating power H of the electrolyzer system under the condition of the minimum number of start-up devices of the electrolyzer at each moment min , and subtract it from the typical output power E of the self-built new energy at each moment t to calculate and determine the minimum power G received by the electrolyzer from the power system at each moment min,t .

[0044] In step S3 of this embodiment, the minimum operating power of the electrolyzer system is specifically calculated by the following formula:

[0045] H min = h min ·L min (4);

[0046] In the formula, h min is the minimum operating power of a single electrolyzer device, and Lmin is the minimum number of start-up devices of the electrolyzer

[0047] Considering the minimum operating power of the electrolyzer and the consumption and utilization of the self-built new energy at each moment, the difference between the two is the minimum power G received by the electrolyzer from the power system at each moment

[0048] G min,t = H min - E t (5).

[0049] Step S4: Determine the potential P of the electrolyzer to participate in the downward load regulation of the power system at each moment according to the power G received by the electrolyzer from the power system at each moment in step S2 t and the minimum power G received by the electrolyzer from the power system at each moment in step S3 min,t , and the calculation is as follows: down,t P

[0050] = G down,t - G t (6). min,t (6).

[0051] Step S5: Determine the maximum potential U for the power received by the electrolyzer from the power system to increase at each moment by subtracting the power G received by the electrolyzer from the power system at each moment in step S2 from the maximum power R received by the electrolyzer from the power system t , and the calculation formula is as follows: t U

[0052] = R - G t (7). t (7).

[0053] In this embodiment, the maximum power R received by the electrolyzer from the power system is determined by the capacity of the connection transformer between the electrolyzer and the external power grid. In reality, since green hydrogen projects will build their own new energy power generation facilities to supply power to their hydrogen production facilities, the connection to the external power grid only solves part of the power supply problem, and its connection power is usually less than the capacity of the electrolyzer. Therefore, the maximum power R received can be understood as a known quantity.

[0054] Step S6: According to the overall load demand D of the power system set at each moment t and the overall minimum output O of other power sources in the power system except new energy power generation t make a difference to determine the surplus new energy power generation power S of the power system at each moment t , and the calculation formula is as follows:

[0055] S t = D t - O t (8);

[0056] The overall load demand D of the power system at the t-th moment in the scheduling cycle in the formula t and the overall minimum output O of other power sources in the power system except new energy power generation t are determined according to the actual operation of the power system scheduling and are used as external input parameters.

[0057] Step S7: According to the maximum lifting potential U of the power received by the electrolyzer from the power system at each moment in step S5 t and the surplus new energy power generation power S of the power system at each moment in step S6 t determine the potential P of the electrolyzer to participate in the upward peak shaving of the power system at each moment up,t , specifically:

[0058] P up,t = min(U t , S t ) (9).

[0059] Step S8: Obtain the potential of the electrolyzer to participate in the power system peak shaving at each moment.

[0060] In the method provided in this embodiment, during the peak shaving process, considering the flexible operation ability of the electrolyzer in the green hydrogen project, it can operate with highly flexible variable loads according to peak shaving requirements, and can even operate beyond the standard load power, realizing the capacity potential of the electrolyzer to participate in power system peak shaving as a flexible resource. During the analysis of the capacity potential, factors such as the operation mode of the electrolyzer, the interactive power with the power system, and the surplus new energy in the large power grid are considered to affect the peak shaving potential, so as to accurately evaluate the potential of the electrolyzer to participate in the upward and downward peak shaving of the power system, explore the value of the electrolyzer as a new type of peak shaving resource in the power system, relieve the power supply pressure of the power system, and contribute to the consumption of surplus new energy in the power system.
