Description

Technical Field

[0001] The present invention relates to the field of power systems, and in particular to a storage medium, a control method, a system and a device for a novel power system. Background Art

[0002] Frequency stability refers to the ability of a system to maintain its frequency within a certain range after being subjected to a disturbance that causes an imbalance in power between the source and the load.

[0003] In traditional power systems, synchronous generators generally have automatic droop characteristics, and the load power of motor-driven machinery such as compressors, fans, and pumps is positively correlated with the speed / frequency. Therefore, system frequency regulation for short-term or small disturbances can be achieved through automatic feedback, while longer-term power differences are achieved through AGC secondary frequency regulation or scheduling.

[0004] In AC power systems dominated by new energy, with the massive integration of renewable energy generation and non-rotating motor loads, as well as the construction of high-voltage DC interconnected systems, the constant power control mode of power electronic converters has led to a serious reduction in the correlation between the power of power supplies, loads, and other equipment and the system frequency, manifesting as an increasingly weak frequency regulation capability. As a result, the frequency stability problem of AC island systems using new energy electrolysis for hydrogen production has become increasingly serious. In existing technologies, when new power systems are disturbed, frequency stability control is generally performed by controlling the charge and discharge of energy storage units within the new power system.

[0005] After research, the inventors found that the existing technical solutions for frequency stability control of new power systems still have at least the following defects:

[0006] The energy storage unit charge and discharge control method to deal with the system frequency disturbance has poor timeliness and effectiveness, and cannot achieve good control effect.

[0007] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0008] The purpose of the present invention is to be able to timely and effectively control the system frequency and improve the control effect.

[0009] The present invention provides a control system for a new type of power system, comprising a full-control power controller for loads, a control unit, a process parameter monitoring unit and a system frequency monitoring unit;

[0010] The control unit includes a main control module, an auxiliary control module and a synthesis module; the main control module is used to generate a main control instruction based on the monitoring data of the process parameter monitoring unit; the auxiliary control module uses the real-time system frequency of the system frequency monitoring unit as a parameter and generates an auxiliary control instruction according to a preset analog control strategy; the synthesis module synthesizes the main control instruction and the auxiliary control instruction into a control instruction for the fully controlled power controller;

[0011] The analog control strategy is generated based on the power and frequency response characteristics of the load; the analog control strategy is used to: when the fluctuation amplitude is less than a preset threshold, calculate the adapted output power corresponding to the load and the real-time system frequency, and generate the auxiliary control instruction based on the adapted output power;

[0012] The fully controlled power controller controls the power of the load according to the control instruction.

[0013] In another aspect of the present invention, a control method for a new power system is provided, wherein the load of the new power system is provided with a full-control power controller, characterized in that the method comprises the steps of:

[0014] S11, generating a main control instruction according to the monitoring data of the process parameter monitoring unit;

[0015] S12. Using the real-time system frequency of the system frequency monitoring unit as a parameter, generating an auxiliary control instruction according to a preset analog control strategy; the analog control strategy is generated based on the power and frequency response characteristics of the load; the analog control strategy is configured to: when the fluctuation amplitude is less than a preset threshold, calculate the adapted output power corresponding to the load and the real-time system frequency, and generate the auxiliary control instruction based on the adapted output power;

[0016] S13. Combining the main control instruction and the auxiliary control instruction into a control instruction for a full-control power controller.

[0017] On the other hand, an embodiment of the present invention provides a control device for a new power system, wherein the control device for the new power system includes a computer program stored on a medium, and the computer program includes program instructions. When the program instructions are executed by a computer, the computer executes the methods described in the above aspects and achieves the same technical effects.

[0018] In another aspect of the embodiment of the present invention, a storage medium is further provided, on which a computer program is stored. When the computer program is executed by a processor, each step of the control method for a new power system as described in any one of the above items is implemented.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The control method of the new power system in the present invention is based on the conventional load control method of the fully-controlled power controller in the existing technology, and adds an auxiliary control quantity to control the stability of the system frequency for small-amplitude disturbances of the system frequency (that is, the fluctuation amplitude is less than the preset threshold); specifically, the present invention reuses the power regulation function of the fully-controlled power controller, and generates an analog control strategy according to the power and frequency response characteristics of the load. In this way, when the fluctuation amplitude is less than the preset threshold, the adaptive output power corresponding to the load and the real-time system frequency can be calculated, and an auxiliary control instruction can be generated according to the adaptive output power; since the auxiliary control instruction in the present invention can simulate the power-frequency characteristics of the source-load power balance of the non-electronic power load according to the power and frequency response characteristics of the load, it can realize automatic feedback power regulation to achieve frequency stability.

[0021] As can be seen from the above, the present invention automatically performs real-time and stable regulation of small-amplitude disturbances through an additional analog control strategy; therefore, the present invention can achieve flexible regulation of the system frequency through moderate power regulation; compared with the simple energy storage device charging and discharging control method for stabilizing the frequency in the prior art, the present invention can avoid the secondary disturbance of the system frequency caused by the charging and discharging action of the energy storage device during small-amplitude disturbances, and thus can obtain better regulation effect during small-amplitude system disturbances.

[0022] On the other hand, the traditional method of regulating system frequency through charging and discharging control of energy storage devices still has the defect of too long response time; the present invention can achieve millisecond-level response to system disturbances, and thus can also effectively reduce the negative impact of disturbances on new power systems.

[0023] On the other hand, in the present invention, the system frequency is no longer adjusted by the charging and discharging actions of the energy storage device when there is a small system disturbance. This can greatly reduce the charging and discharging frequency of the energy storage device, thereby effectively increasing the service life of the energy storage device.

[0029] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0030] Unless expressly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0031] In this document, the terms "first", "second", etc. are used to distinguish two different elements or parts, and are not used to limit specific positions or relative relationships. In other words, in some embodiments, the terms "first", "second", etc. can also be interchangeable with each other.

[0032] Example 1

[0033] In order to be able to control the system frequency in a timely and effective manner and improve the control effect, refer to Figure 1 , an embodiment of the present invention provides a control system for a new power system, including a full-control power controller for loads, a control unit, a process parameter monitoring unit and a system frequency monitoring unit;

[0034] The control unit includes a main control module, an auxiliary control module, and a synthesis module; the main control module is used to generate a main control instruction based on the monitoring data of the process parameter monitoring unit; the auxiliary control module uses the real-time system frequency of the system frequency monitoring unit as a parameter and generates an auxiliary control instruction according to a preset simulation control strategy; the synthesis module synthesizes the main control instruction and the auxiliary control instruction into a control instruction for the fully controlled power controller;

[0035] The analog control strategy is generated based on the power and frequency response characteristics of the load. When the fluctuation amplitude is less than a preset threshold, the analog control strategy calculates the adapted output power corresponding to the load and the real-time system frequency, and generates auxiliary control instructions based on the adapted output power.

[0036] The fully controlled power controller controls the power of the load according to the control instructions.

[0037] In the application scenario of the embodiment of the present invention, the new power system includes a new energy power supply and a load, wherein the new energy power supply can be a wind power device and / or a photovoltaic power generation device; the load can be one or more of electric heating, variable frequency motor, electrolytic rectifier and charging and swapping station.

[0038] Compared with the prior art which simply controls the power of the load based on the operating conditions of the equipment (i.e., the monitoring data of the process parameter monitoring unit), the control unit in the embodiment of the present invention, when generating control instructions, also adds a control strategy (i.e., an analog control strategy) for power control based on the real-time system frequency.

[0039] The control unit in the embodiment of the present invention is a processing device with processing computing capabilities, such as a PLC, a microprocessor, and a processor; in actual applications, the main control module, the auxiliary control module, and the synthesis module in the control unit can be multiple sub-components with a split-type design, each sub-component is provided with a corresponding software module; or they can be multiple software modules provided in one processing device.

[0040] The main control module in the embodiment of the present invention is similar to the control logic of the control unit of the fully controlled power controller in the prior art, and generates a composite power control instruction (i.e., the main control instruction) according to the operating condition of the equipment; on the other hand, the auxiliary control module in the embodiment of the present invention includes an analog control strategy; the analog control strategy is generated according to the power and frequency response characteristics of the load, and can simulate the power-frequency characteristics of the source-load power balance of the non-electronic power load; in this way, when the system frequency fluctuates slightly (less than a preset threshold), the auxiliary control module can calculate the adaptive output power corresponding to the load and the real-time system frequency, and generate an auxiliary control instruction based on the adaptive output power; the auxiliary control instruction can adjust the load power in a timely manner to offset the small fluctuations of the system frequency, thereby achieving real-time frequency stabilization.

[0041] The fully-controlled power controller in the embodiment of the present invention is a power electronic device using fully-controlled power electronic devices, such as IGBTs or IGCTs.

[0042] In the embodiment of the present invention, the synthesis module may synthesize the main control instruction and the auxiliary control instruction in various ways, specifically:

[0043] Taking a fully controlled power controller including a drive circuit and a PWM controlled IGBT as an example, at this time, the main control instruction, the auxiliary control instruction and the control instruction all include the PWM duty cycle.

[0044] In an embodiment of the present invention, the final control instruction can be determined by setting a priority. For example, the priority of the main control instruction is set to be higher than the auxiliary control instruction. In this way, when power control needs to be performed according to the working conditions of the equipment, the synthesis module prioritizes the main control instruction of the main control module as the control instruction for power control; when there is no main control instruction, the synthesis module uses the auxiliary control instruction of the auxiliary control module as the control instruction for power control.

[0045] In addition, the synthesis module can also add the main control instruction and the auxiliary control instruction to obtain the final control instruction; in this way, when there is no main control instruction, the auxiliary control instruction is used as the control instruction for power control; when there is a main control instruction, the result of adding the main control instruction and the auxiliary control instruction (that is, adding the two duty cycles) is used as the control instruction for power control.

[0046] Taking the load as a charging and swapping station as an example, at this time, the power and frequency response characteristics set in the simulation control strategy in the embodiment of the present invention are P∞f i , where i is greater than 1.

[0047] In the embodiment of the present invention, regarding the power and frequency response characteristic P∞f i In the equation, the specific reasonable value of i can be determined by the following formula:

[0048]

[0049] Among them, P max P is the maximum value of the power variation that the load can accept; min is the minimum value of the power variation that the load can accept; f max is the maximum frequency value in the preset threshold; f min is the minimum frequency value among the preset thresholds.

[0050] Power and frequency response characteristics P∞f of the embodiment of the present invention i In the example, the frequency minimum f min Corresponding to the charging power being 0 and the maximum frequency f max Corresponding to 100% charging power, set the power frequency control curve.

[0051] In the embodiment of the present invention, the capacity of the new power system is positively correlated with the acceptable fluctuation amplitude of the system frequency. In practical applications, the fluctuation amplitude of the system frequency can be determined based on a reference frequency of 50 Hz, which is a power frequency. Generally:

[0052] When the new power system exceeds 3GW, the maximum frequency f max Including 50.5Hz; the minimum frequency f minIncluding 49.5Hz;

[0053] When the new power system is less than 3GW, the maximum frequency f max Including 50.2Hz; the minimum frequency f min Including 49.8Hz.

[0054] To sum up, the control method of the new power system in the embodiment of the present invention is based on the conventional load control method of the fully-controlled power controller in the existing technology, and adds an auxiliary control amount to control the stability of the system frequency for small-amplitude disturbances of the system frequency (that is, the fluctuation amplitude is less than the preset threshold); specifically, the embodiment of the present invention reuses the power regulation function of the fully-controlled power controller, and generates an analog control strategy according to the power and frequency response characteristics of the load. In this way, when the fluctuation amplitude is less than the preset threshold, the adaptive output power corresponding to the load and the real-time system frequency can be calculated, and an auxiliary control instruction can be generated according to the adaptive output power; since the auxiliary control instruction in the embodiment of the present invention can simulate the power-frequency characteristics of the source-load power balance of the non-electronic power load according to the power and frequency response characteristics of the load, it can realize automatic feedback power regulation to achieve frequency stability.

[0055] As can be seen from the above, the embodiment of the present invention automatically performs real-time and stable regulation of small-amplitude disturbances through an additional analog control strategy; therefore, the embodiment of the present invention can achieve flexible regulation of the system frequency through moderate power regulation; compared with the method of simply controlling the stable frequency by charging and discharging the energy storage device in the prior art, the embodiment of the present invention can avoid the secondary disturbance of the system frequency caused by the charging and discharging action of the energy storage device during small-amplitude disturbances, and thus can obtain a better regulation effect during small-amplitude system disturbances.

[0056] On the other hand, the traditional method of regulating system frequency through charging and discharging control of energy storage devices still has the defect of too long response time; the embodiments of the present invention can achieve millisecond-level response to system disturbances, and thus can also effectively reduce the negative impact of disturbances on new power systems.

[0057] On the other hand, in the embodiment of the present invention, the system frequency is no longer adjusted by charging and discharging the energy storage device when a small system disturbance occurs. This can significantly reduce the charging and discharging frequency of the energy storage device, thereby effectively increasing the service life of the energy storage device.
