[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that the method shown in the present application is applied to an AGC coordination control system, which has a communication connection with the power system, and the power system includes a new energy AGC and a conventional AGC.

[0048] The control system can be either a terminal or a server. The terminal can be a desktop terminal or a mobile terminal. The mobile terminal can be at least one of a mobile phone, a tablet computer, a laptop computer, etc. The server can be implemented as an independent server or a server cluster composed of multiple servers. This embodiment is described by taking a server as an example.

[0049] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of an AGC coordinated control method according to an embodiment of the present invention. Figure 1 The method comprises the following steps:

[0050] 101. Determine a current system frequency deviation of a power system, wherein the power system includes a new energy AGC and a conventional AGC;

[0051] 102. Determine a regional control deviation value of the power system by using the current system frequency deviation and a preset regional control deviation algorithm;

[0052] When adjusting the output of the AGC, it is necessary to first determine the system frequency deviation of the power system where the AGC is located, so as to determine the regional control deviation value based on the system frequency deviation, wherein the power system includes new energy AGC and conventional AGC. Specifically, the current system frequency deviation of the power system is determined, and the regional control deviation value of the power system is determined using the current system frequency deviation and the preset regional control deviation algorithm. It can be understood that it is necessary to collect the frequency deviation of the power system in real time and execute this method in real time to achieve the output adjustment of the AGC. Therefore, the current system frequency deviation is the real-time system frequency deviation. Among them, the regional control deviation value can reflect the power adjustment amount.

[0053] 103. Determine the control mode of the new energy AGC;

[0054] 104. Perform coordinated control planning processing according to the regional control deviation value and the control mode to determine a target output adjustment instruction and a target AGC, wherein the target output adjustment instruction is used to adjust the output of the target AGC, and the target AGC is at least one of a new energy AGC and a conventional AGC.

[0055] It should be noted that in order to improve the efficiency of green power generation, the control mode of the new energy AGC is first determined. The control mode includes but is not limited to the full consumption mode and the local mode. The full consumption mode means that all the electricity generated by the clean energy is used up without any surplus; the local mode means that the new energy AGC is controlled locally and cannot be remotely controlled. The local mode can be judged by whether the remote control switch of the new energy AGC is turned on. Further, the coordinated control planning is processed according to the regional control deviation value and the control mode to determine the target output adjustment instruction and the target AGC.

[0056] The present invention provides an AGC coordinated control method, the method comprising: determining the current system frequency deviation of an electric power system, the electric power system comprising a new energy AGC and a conventional AGC; using the current system frequency deviation and a preset regional control deviation algorithm to determine the regional control deviation value of the electric power system; determining the control mode of the new energy AGC; performing coordinated control planning processing according to the regional control deviation value and the control mode, and determining a target output adjustment instruction and a target AGC, the target output adjustment instruction being used to adjust the output of the target AGC, the target AGC being at least one of the new energy AGC and the conventional AGC. By adopting the above-mentioned method, when performing output adjustment, the coordinated control planning of the regional control deviation value and the control mode of the new energy AGC is considered, and the target output adjustment instruction and the target AGC obtained thereby, taking into account the control mode of the green new energy AGC, improve the green power generation efficiency in the electric power system.

[0057] See also Figure 2 , Figure 2 FIG. 4 is another flow chart of an AGC coordinated control method according to an embodiment of the present invention. Figure 2 The method shown includes the following steps:

[0058] 201. Determine a current system frequency deviation of a power system, wherein the power system includes a new energy AGC and a conventional AGC;

[0059] It should be noted that step 201 and Figure 1 The contents of step 101 are similar, and are not described here to avoid repetition. For details, please refer to Figure 1 The content of step 101 is shown.

[0060] In a feasible implementation, step 201 includes: obtaining a first current frequency of the power system; and determining a current system frequency deviation of the power system using the first current frequency and a preset rated frequency.

[0061] Exemplarily, the system frequency deviation Δf=f-f0, where f0=50 Hz is the system rated frequency, f is the first current frequency, and Δf is the current system frequency deviation.

[0062] 202. Determine a regional control deviation value of the power system by using the current system frequency deviation and a preset regional control deviation algorithm;

[0063] It should be noted that step 202 and Figure 1 The contents of step 102 are similar and will not be described here to avoid repetition. Figure 1 The content of step 102 is shown.

[0064] In a feasible implementation, the regional control deviation algorithm includes:

[0065] ACE = B*Δf;

[0066] Where ACE is the regional control deviation value, B is the frequency deviation coefficient of the power grid system (MW / HZ), which is generally 1% to 1.5% of the annual expected maximum load of the power grid system, and Δf is the current system frequency deviation.

[0067] 203. Determine the control mode of the new energy AGC;

[0068] It should be noted that step 203 and Figure 1 The contents of step 103 are similar, and are not described here to avoid repetition. For details, please refer to Figure 1 The content of step 103 is shown.

[0069] 204. If the control mode of the new energy AGC is in the full absorption mode and / or the local mode, determining the target AGC to be a conventional AGC;

[0070] It should be noted that the coordinated control plan gives priority to the control mode of the new energy AGC. If the control mode of the new energy AGC is in either the full absorption mode or the local mode, the output adjustment of the new energy AGC cannot be achieved. Therefore, at this time, only the output adjustment of the conventional AGC can be done, and the target AGC is determined to be the conventional AGC.

[0071] 205. Determine a first output adjustment amount of the conventional AGC by using the regional control deviation value;

[0072] 206. Generate a first output adjustment instruction based on the first output adjustment amount;

[0073] 207. Issue the first output adjustment instruction to the conventional AGC, where the target output adjustment instruction includes the first output adjustment instruction;

[0074] Further, the first output adjustment amount of the conventional AGC is determined by using the regional control deviation value, and a first output adjustment instruction is generated, the first output adjustment instruction is used to adjust the output of the conventional AGC according to the first output adjustment amount, so that the adjustment amount AGC of the conventional unit AGC CG =ACE.

[0075] 208. If the control mode of the new energy AGC is not in the full absorption mode, and the control mode of the new energy is not in the local mode, determining that the target AGC is the new energy AGC and the conventional AGC;

[0076] On the contrary, if the control mode of the new energy AGC is not in the full absorption mode and the local mode, then not only can the output of the new energy AGC be adjusted, but the new energy AGC also has spare power to participate in the output adjustment. Therefore, the new energy AGC can be added to the output adjustment at this time to make the output adjustment faster and greener. At this time, it is determined as new energy AGC and conventional AGC.

[0077] 209. Determine a second output adjustment amount of the conventional AGC;

[0078] Furthermore, it is necessary to determine the second output adjustment amount of the conventional AGC, and the output of the conventional AGC is calculated by the following expression: AGC conventional = B conventional * Δf;

[0079] Wherein, AGC conventional is the second output regulation amount, B conventional is the frequency deviation coefficient (MW / HZ) of the power grid system composed only of AGC conventional, which is generally 1% to 1.5% of the annual expected maximum load of the power grid system.

[0080] 2010. Determine a third output adjustment amount of the new energy AGC according to the second output adjustment amount and the regional control deviation value;

[0081] It should be noted that the second output adjustment amount of the conventional AGC can be obtained, and the third output adjustment amount of the new energy AGC can be determined according to the second output adjustment amount and the regional control deviation value. Specifically, AGC new energy = ACE - AGC conventional, that is, the third output adjustment amount = regional control deviation value - the second output adjustment amount.

[0082] 2011. Generate a second output adjustment instruction based on the second output adjustment amount, and generate a third output adjustment instruction based on the third output adjustment amount;

[0083] 2012. Issue the second output adjustment instruction to the conventional AGC, and issue the third output adjustment instruction to the new energy AGC, wherein the target output adjustment instruction includes the second output adjustment instruction and the third output adjustment instruction.

[0084] Further, a second output adjustment instruction is generated based on the second output adjustment amount, and a third output adjustment instruction is generated based on the third output adjustment amount. The second output adjustment instruction is used to adjust the output of the conventional AGC according to the second output adjustment amount, so that the adjustment amount AGC of the conventional unit AGC CG = second output adjustment amount; the third output adjustment instruction is used to adjust the output of the new energy AGC according to the third output adjustment amount, so that the adjustment amount of the new energy AGC AGC 新能源 =The third output adjustment amount.

[0085] In a feasible implementation, after the coordinated control planning process is performed according to the regional control deviation value and the control mode and the target output adjustment instruction and the target AGC are determined, the process further includes: obtaining a second current frequency f of the power system; if the second current frequency f is greater than or equal to the frequency modulation dead zone f d , then the step of determining the current system frequency deviation Δf of the power system is returned to execution until the second current frequency f is less than the frequency modulation dead zone f d .

[0086] The present invention provides an AGC coordinated control method, the method comprising: determining a current system frequency deviation of an electric power system, the electric power system comprising a new energy AGC and a conventional AGC; determining a regional control deviation value of the electric power system by using the current system frequency deviation and a preset regional control deviation algorithm; determining a control mode of the new energy AGC; if the control mode of the new energy AGC is in a full absorption mode and / or a local mode, determining a target AGC as a conventional AGC; determining a first output adjustment amount of the conventional AGC by using the regional control deviation value; generating a first output adjustment instruction based on the first output adjustment amount; issuing the first output adjustment instruction to the conventional AGC, the target output adjustment instruction comprising The first output regulation instruction; if the control mode of the new energy AGC is not in the full absorption mode, and the control mode of the new energy is not in the local mode, the target AGC is determined to be the new energy AGC and the conventional AGC; the second output regulation amount of the conventional AGC is determined; according to the second output regulation amount and the regional control deviation value, the third output regulation amount of the new energy AGC is determined; based on the second output regulation amount, a second output regulation instruction is generated, and based on the third output regulation amount, a third output regulation instruction is generated; the second output regulation instruction is issued to the conventional AGC, and the third output regulation instruction is issued to the new energy AGC, and the target output regulation instruction includes the second output regulation instruction and the third output regulation instruction. With the above method, when performing output regulation, the coordinated control planning of the regional control deviation value and the control mode of the new energy AGC is considered, so that the target output regulation instruction and the target AGC obtained by taking into account the control mode of the green new energy AGC improve the green power generation efficiency in the power system.

[0091] ACE = B*Δf = B*(f-f0);

[0092] Wherein, B is the frequency deviation coefficient (MW / HZ), which is generally 1% to 1.5% of the annual expected maximum load of the power grid system.

If yes, the control ends; if not, return to step 302 until the system frequency f<fd.
