However, these new energies have the characteristics of intermittency and volatility, which brings challenges to the stability and reliability of the power grid. In order to solve this problem, it is necessary to configure an energy storage system on the side of new energy, and a load dynamic control method and system of a generator set in an energy storage mode are developed to balance the output fluctuation of new energy and improve the stability and reliability of the power grid. SUMMARY

[0003] The purpose of the application is to provide a load dynamic control method and system of a generator set in an energy storage mode. In the power system, the energy storage device is used as an auxiliary frequency modulation means to cope with the problem of frequency deviation caused by source-load uncertainty and communication delay. By designing a fractional order PID controller to adjust its output power, the energy storage device can smooth the source-load fluctuation and improve the auxiliary frequency modulation performance of the energy storage system.

[0004] In order to achieve the above purpose, the application adopts the following technical solutions:

[0005] The load dynamic control system of the generator set in the energy storage mode comprises a first SR module, a first OR module, a first NOT module, a first AND module, a second OR module, a second NOT module, a second AND module, a third OR module, a third NOT module, a fourth OR module, a second SR module, a fourth NOT module, a fifth OR module, a fifth OR module, a fifth NOT module, a sixth OR module and a third SR module.

[0006] The output end of the first SR module is connected to the energy storage generator set load limit input, the first NOR module, the third NOR module and the fifth NOR module respectively; the output end of the first OR module is connected to the "R" end of the first SR module and the second OR module respectively; the output end of the first NOR module is connected to the first AND module, the second AND module and the "S" end of the second SR module respectively; the output end of the first AND module is connected to the second OR module; the output end of the second OR module is connected to the energy storage generator set load limit input through the second NOR module; the output end of the second AND module is connected to the second OR module; the output end of the third OR module and the output end of the third NOR module are both connected to the fourth OR module; the output end of the fourth OR module is connected to the "R" end of the second SR module, and the output end of the second SR module is connected to the energy storage generator set load high limit action and the fifth OR module respectively, and the output end of the fifth OR module is connected to the energy storage generator set load limit action; the output end of the fourth NOR module is connected to the third OR module; the output end of the fifth OR module and the output end of the fifth NOR module are both connected to the sixth OR module; the output end of the sixth OR module is connected to the "R" end of the third SR module; and the output end of the third SR module is connected to the fifth OR module and the energy storage generator set load low limit action respectively.

[0007] Further improvement of the application is that the energy storage generator set has been connected to the "S" end of the first SR module in parallel.

[0008] Further improvement of the application is that the power channel total failure, the steam turbine has been tripped and the energy storage generator set has been disconnected are all connected to the first OR module, and the energy storage generator set has been disconnected is also connected to the third OR module and the fifth OR module.

[0009] Further improvement of the application is that the energy storage generator set load greater than the high limit value is connected to the first AND module and the "S" end of the second SR module; and the energy storage generator set load less than the high limit value and the high regulation instruction less than 10% are all connected to the third OR module.

[0010] Further improvement of the application is that the energy storage generator set load initial load is connected to the fourth NOR module.

[0011] The energy storage generator set load less than the low limit value is connected to the second AND module and the "S" end of the third SR module respectively.

[0012] The energy storage generator set load greater than the low limit value and the high regulation instruction greater than 90% are all connected to the fifth OR module.

[0013] The method for dynamic control of the load of a generator set in an energy storage mode is based on the dynamic control system of the load of the generator set in the energy storage mode, and comprises the following steps:

[0014] To determine the actual working status of the energy storage generator set load limiting, when the energy storage generator set is connected to the grid (1), the load limiting of the energy storage generator set after the first SR module is set to 1; when the power channel is completely faulty (1), or the turbine has tripped (1), or the energy storage generator set has been disconnected (1), the output of the first OR module triggers the "R" terminal of the first SR module, ultimately resulting in the load limiting of the energy storage generator set being set to 0.

[0015] A further improvement of the present invention is that it further includes:

[0016] To determine the actual operating status of the energy storage generator set under load limitation, if none of the following conditions are met, then the energy storage generator set is considered to be connected to the grid (condition 1); Condition 1: The energy storage generator set is connected to the grid (condition 1) and the load of the energy storage generator set is greater than the upper limit (condition 0); Condition 2: All power channels are faulty (condition 0), the turbine has tripped (condition 0), and the energy storage generator set has been disconnected (condition 0); Condition 3: The energy storage generator set is connected to the grid (condition 1) and the load of the energy storage generator set is less than the lower limit (condition 0).

[0017] A further improvement of the present invention is that it further includes:

When the load of the energy storage generator set is greater than the limit value of 1, the load limit action of the energy storage generator set after passing through the second SR module is 1. When the energy storage generator set is connected to the grid (0), or disconnected (1), or the load of the energy storage generator set is less than the limit value of 1, or the high-adjustment command is less than 10% (1), or the initial load of the energy storage generator set is 0, the output of the fourth OR module triggers the "R" terminal of the second SR module, ultimately causing the load limit action of the energy storage generator set to be 0.

[0019] A further improvement of the present invention is that it further includes:

[0020] To determine the actual working status of the energy storage generator set load limiting action, when the output of the second SR module is 1 or the load of the energy storage generator set is less than the lower limit value, the energy storage generator set load limiting action is 1.

[0021] A further improvement of the present invention is that it further includes:

[0022] The actual working status of the energy storage generator set's load low limit action is determined. When the load of the energy storage generator set is less than the low limit value of 1, the load low limit action of the energy storage generator set after passing through the third SR module is 1. When the energy storage generator set is connected to the grid (0), or disconnected (1), or the load of the energy storage generator set is greater than the low limit value of 1, or the high-adjustment command is greater than 90% (1), the output of the sixth OR module triggers the "R" terminal of the third SR module, ultimately causing the load low limit action of the energy storage generator set to be 0.

[0023] Compared with the prior art, the application has at least the following beneficial technical effects:

[0050] Example 2

[0051] like Figure 1 As shown, the generator set load dynamic control method in energy storage mode provided by the present invention includes:

[0052] The first step is to determine the actual working state of the energy storage generator set load limit input 029. When the energy storage generator set has been connected to the grid 001 is 1, the energy storage generator set load limit input 029 after the first SR module 012 is 1; when the power channel is completely failed 002 is 1, or the turbine has been tripped 003 is 1, or the energy storage generator set has been disconnected 004 is 1, the output end of the first OR module 013 triggers the "R" end of the first SR module 012, and finally causes the energy storage generator set load limit input 029 to be 0;

[0053] The second step is to determine the actual working state of the energy storage generator set load limit input 030. When all the following conditions are not met, the energy storage generator set has been connected to the grid 001 is 1; the second step determination condition one: the energy storage generator set has been connected to the grid 001 is 1 and the energy storage generator set load is greater than the high limit value 005 is 0; the second step determination condition two: the power channel is completely failed 002 is 0 and the turbine has been tripped 003 is 0 and the energy storage generator set has been disconnected 004 is 0; the second step determination condition three: the energy storage generator set has been connected to the grid 001 is 1 and the energy storage generator set load is less than the low limit value 009 is 0;

[0054] The third step is to determine the actual working state of the energy storage generator set load high limit action 031. When the energy storage generator set load is greater than the high limit value 005 is 1, the energy storage generator set load high limit action 031 after the second SR module 022 is 1; when the energy storage generator set has been connected to the grid 001 is 0, or the energy storage generator set has been disconnected 004 is 1, or the energy storage generator set load is less than the high limit value 006 is 1, or the high adjustment instruction is less than 10% 007 is 1, or the energy storage generator set load is the initial load 008 is 0, the output end of the fourth OR module 021 triggers the "R" end of the second SR module 022, and finally causes the energy storage generator set load high limit action 031 to be 0;

[0055] The fourth step is to determine the actual working state of the energy storage generator set load limit action 032. When the output end of the second SR module 022 is 1 or the energy storage generator set load is less than the low limit value 009 is 1, the energy storage generator set load limit action 032 is 1 at this time;

[0056] The fifth step is to determine the actual working status of the low load limit action 033 of the energy storage generator set. When the load of the energy storage generator set is less than the low limit value (009), the low load limit action 033 of the energy storage generator set after passing through the third SR module 028 will be 1. When the energy storage generator set is connected to the grid (001), or the energy storage generator set is disconnected (004), or the load of the energy storage generator set is greater than the low limit value (010), or the high-adjustment command is greater than 90% (011), the output terminal of the sixth OR module 027 will trigger the "R" terminal of the third SR module 028, ultimately causing the low load limit action 033 of the energy storage generator set to be 0.

[0057] Example 3

[0058] like Figure 2 As shown, through the implementation and application of the technology of this invention within the simulation range, specifically from 00:00 to 24:00, the charging and discharging curves are stable throughout the entire charging and discharging process. Furthermore, the two curves can complement and adjust each other, demonstrating good control within the 60% to 100% charging and discharging range. This meets the application requirements of the energy storage generator set under different operating conditions throughout the day, enabling on-demand adjustment and control of the unit load. Simultaneously, it satisfies the goal of responding to grid peak shaving, providing a guarantee for the stable and safe operation of the energy storage generator set.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.

When the load of the energy storage generator set is greater than the high limit value (005) is 1, the energy storage generator set load high limit action (031) after passing through the second SR module (022) is 1. When the energy storage generator set is connected to the grid (001) is 0, or the energy storage generator set is disconnected (004) is 1, or the load of the energy storage generator set is less than the high limit value (006) is 1, or the high adjustment command is less than 10% (007) is 1, or the initial load of the energy storage generator set (008) is 0, the output terminal of the fourth OR module (021) triggers the "R" terminal of the second SR module (022), which ultimately causes the energy storage generator set load high limit action (031) to be 0.

9. The method for dynamic load control of a generator set in energy storage mode according to claim 8, characterized in that, Also includes: Determine the actual working status of the load limiting action (032) of the energy storage generator set. When the output terminal of the second SR module (022) is 1 or the load of the energy storage generator set is less than the lower limit value (009), then the load limiting action (032) of the energy storage generator set is 1.

10. The method for dynamic load control of a generator set in energy storage mode according to claim 9, characterized in that, Also includes: The actual working status of the low load limit action (033) of the energy storage generator set is determined. When the load of the energy storage generator set is less than the low limit value (009) is 1, the low load limit action (033) of the energy storage generator set after passing through the third SR module (028) is 1. When the energy storage generator set is connected to the grid (001) is 0, or the energy storage generator set is disconnected (004) is 1, or the load of the energy storage generator set is greater than the low limit value (010) is 1, or the high adjustment command is greater than 90% (011) is 1, the output terminal of the sixth OR module (027) triggers the "R" terminal of the third SR module (028), which ultimately causes the low load limit action (033) of the energy storage generator set to be 0.
