Description

Technical Field

[0002] With the rapid integration of photovoltaic (PV) power generation into distribution networks, problems such as voltage fluctuations, current overloads, and power imbalances caused by PV integration at the distribution substation level are becoming increasingly prominent. To address these challenges, existing technologies largely rely on centralized dispatching or fixed power limits, lacking consideration for communication network conditions. This makes them prone to control failures in the event of packet loss or delays, leading to untimely PV power regulation and reduced grid security in the distribution substation area.

[0003] To address these challenges, existing technologies typically employ centralized control schemes. These schemes involve a master station or controller deployed at the transformer side of the distribution area, which calculates power levels based on collected grid status information and issues power regulation commands to each photovoltaic inverter within the area. The effectiveness of this approach heavily relies on the bidirectional communication link between the control center and each photovoltaic inverter. However, in real-world operating environments, communication networks are frequently affected by electromagnetic interference, channel congestion, or equipment failures, leading to increased communication delays and data packet loss.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 As shown, Figure 1 This is a flowchart illustrating an embodiment of a transformer-side photovoltaic adaptive adjustment method based on communication reliability provided by the present invention. The method includes: S101: Real-time acquisition of operating parameters of the transformer substation and communication status information between the transformer substation and the photovoltaic inverter within the transformer substation.

[0033] For example, operating parameters such as voltage, current, load, and maximum allowable output of the transformer in the distribution area are collected in real time, and communication status information between the transformer side and the photovoltaic inverter in the distribution area is obtained in real time through the transformer side communication equipment, including communication delay, communication link packet loss rate and link quality.

[0034] S102: Determine communication reliability indicators based on communication status information.

[0035] For example, the communication reliability index between the transformer side and the photovoltaic inverter within the distribution area is determined according to the following formula: ; in, As a communication reliability indicator, and These are the weighting coefficients. , <1, For maximum communication latency, Let be the packet loss rate of the communication link at time t. Let t be the communication delay at time t.

[0036] S103: Determine the available output power of the photovoltaic inverter based on the operating parameters of the transformer substation.

[0037] For example, the available output power of a photovoltaic inverter depends on the load in the distribution area. With the transformer's maximum allowable output The available output power of the photovoltaic inverter is determined according to the following formula: ; in, Let be the available output power at time t. This is the maximum allowable output of the transformer. Let t be the load of the transformer area at time t.

[0038] S104: If the communication reliability index is less than the preset communication reliability threshold, the available output power is adjusted based on the transformer area operating parameters and the ratio of the communication reliability index to the communication reliability threshold to determine the final output power of the photovoltaic inverter.

[0039] For example, if the communication reliability index is less than a preset communication reliability threshold, the communication reliability is low, and the photovoltaic output needs to be reduced by adjusting the communication reliability to ensure the safety of the transformer area. The communication reliability adjustment amount is determined based on the ratio of the communication reliability to the communication reliability threshold, as shown in the following formula: ; Furthermore, the initial output power is determined according to the following formula: ; in, For communication reliability adjustment, This is the maximum allowable output of the transformer.

Let be the voltage of the transformer area at time t. This is the minimum voltage value in the transformer substation area. This represents the maximum voltage value of the transformer substation.

[0041] Finally, the final output power is determined according to the following formula: ; in, This is the initial output power. As a voltage safety factor, This represents the final output power.

[0042] S105: If the communication reliability index is greater than or equal to the communication reliability threshold, the available output power is adjusted based on the operating parameters of the transformer area to determine the final output power of the photovoltaic inverter.

[0043] For example, if the communication reliability index is greater than or equal to the communication reliability threshold, and maximizing the voltage output is required, the available output power is directly adjusted based on the substation operating parameters to determine the final output power of the photovoltaic inverter. Specifically, the voltage safety factor is determined according to the following formula: ; in, Let be the voltage safety factor at time t. Let be the voltage of the transformer area at time t. This is the minimum voltage value in the transformer substation area. Maximum voltage of the transformer area Ultimately, according to Determine the final output power, where, Let be the available output power at time t. Let be the voltage safety factor at time t. Let be the final output power at time t.

[0044] After obtaining the final output power, the photovoltaic power is dynamically adjusted based on real-time measured load and voltage: ; in, Let be the final output power at time t+1. Let be the final output power at time t. To adjust the step size coefficient, This is the maximum allowable output of the transformer. Let t be the load of the transformer area at time t.

[0045] The final output power and the predicted power for the next moment are simultaneously sent to the photovoltaic inverter. The power change amplitude is controlled by adjusting the step size coefficient to avoid voltage oscillation caused by inverter output fluctuations.

[0046] As described above, the present invention obtains the operating parameters of the transformer substation and the communication status information between the transformer substation and the photovoltaic inverter in real time, and determines the communication reliability index between the transformer substation and the photovoltaic inverter based on the communication status information, thereby evaluating the reliability of the communication link in real time through the reliability index.

[0047] Furthermore, based on the operating parameters of the transformer substation, the available output power of the photovoltaic inverter is determined. By comparing the communication reliability index with the preset communication reliability threshold, the available output power is adaptively adjusted. This can proactively avoid safety risks such as grid overvoltage and overload that may be caused by the loss or severe delay of control commands, and significantly enhance the stability of the entire photovoltaic control system in unreliable communication environments.

Let t be the communication delay at time t.

[0054] In the available output power determination module 13 of the photovoltaic inverter, the operating parameters of the transformer substation include the substation load and the maximum allowable output of the transformer. The available output power of the photovoltaic inverter is determined according to the following formula: ; in, Let be the available output power at time t. This is the maximum allowable output of the transformer. Let t be the load of the transformer area at time t.

[0055] In the first power adjustment module 14, the operating parameters of the transformer area also include the transformer area voltage, and the communication reliability adjustment amount is determined according to the ratio of communication reliability to the communication reliability threshold. The initial output power is determined using the formula shown below: ; in, For communication reliability adjustment, This is the maximum allowable output of the transformer.
