Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to an automatic power absorption device, method, equipment and medium for distributed photovoltaic power generation. Background Technology

[0002] Distributed photovoltaic (PV) systems typically refer to small-scale power generation systems located near users, utilizing decentralized resources and generally connected to power grids with voltage levels below 35 kV. They have small installation capacities, numerous installation points, and are usually installed on residential rooftops, supplying electricity to nearby users along with the public grid. The focus is on user-side self-consumption with surplus electricity fed into the grid, adhering to the principles of localized adaptation, clean and efficient operation, decentralized layout, and proximity utilization. As an important component of renewable energy, PV power generation's technological development and application are crucial for achieving sustainable development goals. Distributed PV systems are widely used due to their flexible deployment on building rooftops. Most distributed PV systems are connected to the public grid, supplying electricity to nearby users along with the grid. They offer advantages such as relatively low output power, low pollution, significant environmental benefits, and the ability to alleviate localized power shortages to some extent.

[0003] Large-scale integration of distributed photovoltaic (PV) power, due to its inherent intermittent and fluctuating power generation characteristics, can lead to reverse power flow—where electricity flows from the distributed PV system back to the grid—during periods of abundant sunshine when the generated power may exceed local load demand. In such cases, if the grid's regulation capacity is limited or load characteristics change abruptly, it can trigger reverse overload problems in the distribution area. This manifests as reverse voltage at some nodes, excessive current flowing through certain lines or equipment in the grid, and exacerbated power imbalances. This can not only affect the power quality and stability of the grid but also damage grid equipment and even threaten the safe operation of the grid.

[0004] Therefore, there is an urgent need to propose an automatic absorption device, method, equipment, and system for distributed photovoltaic (PV) systems to address the technical problem of the impact of the intermittent and fluctuating power generation characteristics of distributed PV on the power quality and stability of the power grid.

Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this invention.

[0040] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0041] Method Implementation Examples

[0042] According to embodiments of the present invention, an automatic power consumption device for distributed photovoltaic (PV) systems is provided, such as... Figure 1 The diagram shown is a structural schematic of the automatic power absorption device for a distributed photovoltaic power station provided in this embodiment. The automatic power absorption device for a distributed photovoltaic power station according to this embodiment includes a data acquisition module 11, a smart energy module 12, and a control module 13.

[0043] The data acquisition module 11 is used to collect the operation information of the distribution area terminal equipment and transmit it to the smart energy module 12 via HPLC and / or LoRa. The data acquisition module 11 is deployed in each distribution area, including smart converged terminals and distribution area concentrators. The distribution area terminal equipment includes photovoltaic modules, inverters, energy storage modules, transformers, grid-connected boxes, protocol converters, and electrical equipment. By connecting with terminal equipment such as transformers, distribution boxes, and smart meters in the distribution area, it collects distribution area operation information such as voltage, current, power factor, active power, reactive power, and real-time operating status of each electrical device. For example, for distribution boxes in office buildings, it collects the power consumption data of each floor; for charging piles in parking lots, it collects information such as charging power and charging time; for streetlights, it collects their power consumption and lighting time. Part of this data is transmitted using HPLC (High-speed Power Line Carrier Communication) technology, utilizing the existing power line network within the park, while the other part is transmitted via LoRa (Long Range Radio) technology to ensure stable and comprehensive data collection before being sent to the smart energy module 12.

[0044] The smart energy module 12 is used to calculate the power consumption value based on the operation information of the distribution area terminal equipment and send the power consumption value to the control module 11. After receiving the distribution area operation information from the data acquisition module 11, the smart energy module 12 calculates the power consumption value. For example, it calculates the overall power consumption based on the real-time power data of each electrical device and historical power consumption patterns. If many office devices and commercial facilities are operating simultaneously during daytime office hours, the smart energy module 12 will calculate that the power consumption value is higher at this time; while at night, most devices are turned off, and the power consumption value is significantly reduced. At the same time, the smart energy module 12 also analyzes the trend of the power consumption value to determine whether there is any abnormal power consumption, such as a sudden surge in power consumption caused by the abnormal start-up of high-power equipment in a certain area.

[0045] The control module 13 is used to send configuration commands to the smart energy module 12 based on the relationship between the absorption value and the absorption threshold, and to control the smart energy module 12 to adjust the operating parameters of the terminal equipment in the distribution area. The control module 13 presets the absorption threshold, which is determined based on factors such as power supply contracts, energy costs, and equipment safety operation requirements. For example, during periods of tight power supply, the absorption threshold is set relatively low to avoid exceeding the quota allocated by the power company and incurring high electricity bills or power supply risks; while when power supply is sufficient and prices are low, the threshold can be appropriately increased to make full use of low-priced power resources.

[0046] When the absorption value calculated by the smart energy module 12 approaches or exceeds the absorption threshold, the control module 13 sends a configuration command to the smart energy module 12. The smart energy module 12 then adjusts the operating parameters of the terminal equipment in the distribution area according to the command. For example, for some interruptible equipment (such as air conditioners and lighting equipment in non-critical areas), the smart energy module 12 reduces its operating power or suspends operation for a period of time through control signals to reduce overall power absorption. For equipment with energy storage functions (such as energy storage battery systems within the park), the smart energy module 12 controls it to discharge to supplement power demand, thereby balancing the relationship between the absorption value and the absorption threshold, achieving optimized allocation and efficient utilization of power resources, reducing the park's electricity costs, and improving the level of intelligent energy management.

[0047] like Figure 2 The diagram shown is a schematic representation of the distributed photovoltaic system provided in this embodiment.

[0048] The device provided in this embodiment includes a data acquisition module 11, which collects the operation information of the distribution area terminal equipment and transmits it to the smart energy module via HPLC and / or LoRa. This allows for comprehensive collection of the operation information of the distribution area terminal equipment, covering various key data related to energy consumption. The use of HPLC and / or LoRa communication ensures high efficiency and stability of data transmission. Even in complex distribution area environments, data can be accurately and promptly transmitted to the smart energy module. The smart energy module 12 calculates the energy consumption value based on the operation information of the distribution area terminal equipment and sends the value to the control module, comprehensively considering factors such as the power generation of distributed photovoltaic systems within the distribution area, real-time changes in electricity load, and the status of energy storage devices. Through precise calculations, a suitable absorption value for the distribution area can be obtained, providing a scientific basis for subsequent control decisions. Control module 13 sends configuration commands to the smart energy module based on the relationship between the absorption value and the absorption threshold, controlling the smart energy module to adjust the operating parameters of the distribution area's terminal equipment. This intelligent and flexible control method effectively improves the comprehensive energy utilization efficiency within the distribution area, reducing the impact on and dependence on the power grid. The coordinated operation of the entire automatic absorption device helps improve the overall stability and reliability of the distributed photovoltaic distribution area. Real-time monitoring and dynamic adjustment enable timely responses to various emergencies and abnormal operating conditions. Reasonable absorption control also helps extend the service life of equipment within the distribution area, reduce equipment failure rates, and improve the overall operational quality and reliability of the distribution area, providing users with a more stable and continuous power supply.

[0049] In one embodiment, such as Figure 3As shown in the flowchart, the control module of the automatic grid connection device for distributed photovoltaic areas provided in this embodiment is configured as follows: The control module 13 is further configured as follows:

[0050] The visualization unit receives the distribution area operation information of the terminal equipment in the distribution area sent by the smart energy module 12. This information, along with the absorption value, is displayed through the visualization unit. This operation information includes data such as voltage, current, power factor, active power, and reactive power of each terminal equipment in the distribution area (e.g., transformers, distribution boxes, smart meters, and various electrical devices), and may also include real-time operating status. By receiving this information, the visualization unit obtains first-hand data on the operation of the distribution area equipment, providing a data foundation for subsequent display and analysis. Personnel in the control module 13 can set the absorption threshold X and the amplitude modulation unit Y through the visualization unit.

[0051] The device provided in this embodiment centrally receives and displays the operating information and consumption value of the terminal equipment in the distribution area through a visualization unit. Operators do not need to switch between multiple systems or data sources to view data and can flexibly set the consumption threshold X and amplitude modulation unit Y. This provides a comprehensive and accurate basis for decision-making to achieve precise energy regulation. By observing the visualized distribution area operating information, the device can quickly locate the equipment fault point or the source of abnormal data.

[0052] In one embodiment, such as Figure 4 The diagram shown is a management flowchart of the automatic grid connection device for a distributed photovoltaic system provided in this embodiment. The control module 13 is specifically configured as follows:

[0053] The smart energy module 12 obtains the specific power flow direction and current transformer capacity of the transformer area by acquiring the transformer area operation information from the master table in the data acquisition module, and obtains the absorption value.

[0054] When the absorption value is less than the absorption threshold, an inverter power reduction command is sent to the smart energy module 12 to control the smart energy module 12 to reduce the inverter power of the distribution area terminal equipment by one unit.

[0055] When the absorption value is greater than the absorption threshold, an inverter power increase command is sent to the smart energy module 12 to control the smart energy module 12 to increase the inverter power of the distribution area terminal equipment by one unit.

[0056] The inverter can be configured to increase or decrease units, and the control module can adjust the unit, which can be a percentage reduction or a fixed value reduction.

[0057] The device provided in this embodiment, based on the total meter readings of the distribution area from the data acquisition module, can accurately obtain the power flow direction and the current transformer capacity, thereby accurately calculating the absorption value and controlling the inverter power to adjust up or down. This effectively balances the power generation and consumption within the distribution area. When the absorption value is less than a threshold, the inverter power is reduced to prevent excessive power injection into the grid, which could cause instability such as reverse power flow. When the absorption value is greater than the threshold, the power is increased to promptly fill the power shortage, ensure a stable power supply, achieve precise energy scheduling and supply-demand balance, and improve energy utilization efficiency.

[0058] In one embodiment, the control module 13 further includes an adjustment feedback unit, which is used to reacquire the operating information of the transformer area to determine the absorption value. If the absorption value is still less than the absorption threshold, it returns to the power reduction step. If the absorption value is greater than the absorption threshold, it returns to the power increase step.

[0059] The device provided in this embodiment uses a feedback adjustment unit to re-acquire the operating information of the distribution area to re-determine the absorption value, enabling real-time tracking of changes in energy supply and demand. When the absorption value still does not meet the requirements (less than or greater than the absorption threshold), it promptly returns to the corresponding power adjustment loop for further adjustment, ensuring that the inverter power can continuously adapt to the actual electricity demand and power generation situation of the distribution area. This achieves more precise dynamic matching of energy supply and demand, avoids the continuous existence of energy oversupply or undersupply, and effectively improves energy utilization efficiency.

[0060] In one embodiment, the inverter converts the direct current (DC) power from the photovoltaic (PV) modules into alternating current (AC) power, connects it to the grid, and then transmits it to the internet via a transformer. The inverter also allows for local log queries of the PV output, enabling local power regulation.

[0061] The protocol converter draws power from the inverter's power input port and the grid connection box.

[0062] The communication gateway extends the communication interface of the inverter to establish a data link between the protocol converter and the inverter.

[0063] The protocol converter communicates with the smart energy module via an HPLC communication link, using LoRa as a backup communication link.

[0064] The converged terminal connects to the smart energy module via an RS485 interface to complete data interaction between the converged terminal and the smart energy unit.

[0065] The device provided in this embodiment converts the direct current (DC) generated by photovoltaic (PV) modules into alternating current (AC), achieving an effective conversion of electrical energy form and enabling its smooth connection to the power grid for transmission and use. A transformer further facilitates grid connection, ensuring that the electrical energy is integrated into the grid at a suitable voltage level, meeting grid access requirements. This achieves efficient transmission of PV energy from the generation end to the grid, promoting the effective utilization of PV power generation, increasing the proportion of renewable energy in the energy supply system, and enabling local log queries of PV output. This provides detailed data records for operation and maintenance personnel. The protocol converter draws power from the inverter's transmission port and grid-connected box. This power draw method utilizes the existing power supply lines of the inverter and grid-connected box, eliminating the need for separate power supply lines, simplifying wiring complexity, and reducing construction costs. The communication interface of the inverter is expanded to establish a data link between the protocol converter and the inverter. This allows the protocol converter to accurately obtain relevant data from the inverter, further expanding the communication interface of the entire system. The protocol converter communicates with the smart energy module through an HPLC communication link, with LoRa as a backup communication link, ensuring continuous data transmission, improving the reliability of the entire communication system, and reducing the risk of the energy management system malfunctioning due to communication failures.
