Description

Technical Field

[0001] This application relates to the fields of power electronics and new energy power generation control technology, and in particular to a response control method, equipment and medium for a grid-type converter. Background Technology

[0002] With the increasing penetration of renewable energy sources such as wind power and photovoltaics in the power system, the power system exhibits the "dual high" characteristics of "high proportion of renewable energy" and "high proportion of power electronic equipment." Most renewable energy units are located at the end of the grid, connected to the system via long-distance transmission lines and multiple transformers, resulting in a weak grid characteristic with a low short-circuit ratio (Low-SCR) at the grid connection point. Under weak grid conditions, the system's equivalent impedance changes drastically. Traditional grid-following (GFL) converters rely on phase-locked loops (PLLs) for synchronization, which easily leads to sub- / super-synchronous oscillations and cannot provide inertia and damping support for the system, resulting in poor anti-interference capabilities.

[0003] Grid-Forming (GFM) converters, especially their Virtual Synchronous Generator (VSG) technology, actively provide voltage and frequency support to the grid by simulating the external characteristics of a synchronous machine, exhibiting excellent stability under weak grid conditions. However, to simulate the inertia and damping of a synchronous machine, the power loop, voltage loop, and current loop of the VSG are nested, resulting in a high dynamic order, slow power response, and difficulty in quickly tracking the drastic fluctuations in renewable energy power.

[0074] In specific embodiments, such as Figure 2 As shown, for step S12, unlike the traditional voltage and current dual closed-loop control, this application introduces a power difference feedforward compensation loop control. This structure innovatively introduces a power difference feedforward channel, forming a feedforward-feedback coordinated composite control mechanism. The power difference feedforward compensation loop, as the key to improving dynamic performance, is directly embedded into the current and voltage dual closed-loop control structure. Its working mechanism is as follows:

[0079] It should be noted that the embodiments provided in this application are only one possible implementation method, but are not limited to this only implementation method. Users can set their own implementation methods according to their needs.

[0080] S13: Inject the voltage reference value and power deviation into the current-voltage dual closed loop so that the current-voltage dual closed loop outputs the corrected voltage and improves the response speed of the grid-type converter.

[0081] In specific embodiments, such as Figure 4 As shown, first, the power deviation (d-axis power deviation) is... and q-axis power deviation (Through feedforward tuner) The process is performed to generate the corresponding voltage reference correction. Its mathematical model is as follows:

[0082] ;

[0086] in, Characterizing active power The corresponding feedforward tuner; Characterizing reactive power The corresponding feedforward tuner; and Both characterize adjustable feedforward gain; Characterizing d-axis power deviation The corresponding voltage reference correction amount; Characterizing q-axis power deviation The corresponding voltage reference correction.

[0087] The current and voltage dual closed loop is responsible for precise control, generating voltage correction values. and The reference value is directly superimposed onto the input of the voltage outer loop, acting in parallel with the output of traditional PI (Proportional-Integral) control to form a composite control signal. The voltage outer loop and current inner loop are based on traditional PI control. The voltage outer loop achieves DC bus voltage tracking by adjusting the reference current, while the current inner loop utilizes a feedforward decoupling strategy to counteract the grid's dq-axis coupling effect, thereby improving dynamic response speed. The PI parameters are tuned according to filter characteristics and system bandwidth to balance steady-state accuracy and improve anti-interference capability. The specific implementation of this composite control architecture is as follows:

[0088] ;

[0089] ;

[0091] ;

[0092] ;

[0093] ;

[0097] It should be noted that, and In the next closed-loop control, it is equivalent to the d-axis component of the actual voltage. and the actual voltage q-axis component .

[0098] It's easy to understand that, to achieve independent control of the dq axes, feedforward decoupling terms are introduced in both the voltage outer loop and the current inner loop. Specifically, in the voltage loop... , To compensate for the coupling effect between the d and q axes. This is achieved by introducing [a certain element] into the inner current loop. , This achieves complete decoupling of the inner current loop. Furthermore, to ensure the system maintains good stability while improving dynamic performance, the feedforward gain needs to be adjusted. and Co-tuning with the PI parameter can improve the response speed by increasing the feedforward gain, but it will reduce the system damping ratio. Therefore, the proportional gain needs to be adjusted synchronously to maintain a suitable damping ratio and avoid system overshoot and oscillation.

[0099] Furthermore, it's easy to understand that this composite structure achieves multiple coordinated control mechanisms. Firstly, it enables rapid compensation of the feedforward path. When power commands change abruptly or grid disturbances occur, the power difference feedforward path can immediately generate a voltage correction, compensating for power disturbances in advance and significantly reducing the regulation lag caused by error accumulation in traditional PI controllers. Simultaneously, the PI controller in the voltage outer loop continues to accurately eliminate steady-state errors, ensuring the system's steady-state performance and zero steady-state error tracking. In addition, the parallel connection of the feedforward and feedback paths changes the overall forward transfer function of the system, effectively enhancing the integral term coefficient, increasing the system's undamped natural frequency, and expanding the system bandwidth, thereby improving the dynamic response speed without changing the system order. Since the dq-axis structure is similar, the simplified transfer function diagram of the d-axis is shown below. Figure 5 As shown, the system's total output is:

[0103] It should be noted that the embodiments provided in this application are only one possible implementation method, but are not limited to this only implementation method. Users can set their own implementation methods according to their needs.

[0104] The grid-type converter response control method provided in this application is applied to a grid-type control network including a current-voltage dual closed loop, a virtual impedance control loop, a power calculation loop, and a power difference feedforward compensation loop. This grid-type control network adds a power difference feedforward compensation loop compared to conventional grid-type control networks. As shown in the specific steps of the method, the power parameters calculated by the power calculation loop are used as inputs to the power difference feedforward compensation loop, while the power deviation output by the power difference feedforward compensation loop is used as an input to the current-voltage dual closed loop. This ensures that the current-voltage dual closed loop outputs a corrected voltage and improves the response speed of the grid-type converter. In other words, when there is a sudden change in power command or grid disturbance, the power difference feedforward compensation loop can immediately generate a power deviation to compensate for the power disturbance in advance. This significantly reduces the regulation lag caused by error accumulation in the PI controller of the current-voltage dual closed loop, ensuring the steady-state performance and zero steady-state error tracking of the system, thereby achieving the goal of improving the response speed.

[0105] In other words, this application provides a response control method for grid-type converters. Without changing the original power control loop structure, it achieves rapid and forward-looking compensation for power disturbances by feeding the power deviation forward to the voltage reference value calculation stage, thereby significantly improving dynamic response performance while ensuring system stability.
