Description

Technical Field

[0001] This invention relates to the field of power system technology, specifically to a distribution network differentiation optimization device based on load forecasting and grid-based reconfiguration. Background Technology

[0002] As power systems develop towards intelligence and diversification, the distribution network, as a crucial link connecting power sources and users, directly impacts the overall efficiency of the power system through its operational stability, economy, and power supply quality. Currently, the distribution network faces numerous challenges, including uneven load distribution, diverse energy supply types, and strong randomness in load fluctuations. Especially with the large-scale integration of distributed energy resources, the power supply structure of the distribution network has become increasingly complex, with significant differences in load demand across different regions and time periods. Traditional distribution network regulation methods are no longer sufficient to meet the needs of refined and differentiated operational optimization.

[0003] Existing power distribution network optimization technologies primarily focus on the balanced distribution of overall load, lacking precise adaptation to the load characteristics of different gridded areas. Furthermore, they suffer from issues such as lag in response, insufficient adjustment precision, and cumbersome operation in energy ratio regulation. For example, when distributed energy supply is sufficient in a certain area or there is a sudden increase in load, the energy supply ratio in that area cannot be adjusted quickly and accurately, leading to energy waste or power shortages. Simultaneously, existing regulation devices mostly employ direct mechanical transmission methods, making them susceptible to environmental interference. Moreover, when multiple branches are coordinated for regulation, it is difficult to guarantee the stability of the total supply current, thus affecting the reliability of the power distribution network.

[0004] Furthermore, the need for distribution network optimization based on load forecasting is becoming increasingly urgent. However, existing devices struggle to effectively combine load forecasting results with real-time energy ratio adjustment, failing to achieve differentiated and precise control based on grid-based reconfiguration. Therefore, developing a differentiated optimization device that can adapt to the needs of load forecasting and grid-based reconfiguration, and can quickly and accurately adjust the energy supply ratio to ensure the stable operation of the distribution network, has become a pressing technical problem to be solved in the current distribution network field. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a distribution network differentiation optimization device based on load forecasting and grid-based reconfiguration.

[0006] The technical solution to achieve the purpose of this invention is: a distribution network differential optimization device based on load forecasting and grid-based reconfiguration, including a box, wiring components, regulating components, driving components and a partition, wherein the partition is disposed inside the box and divides the inside of the box into two independent areas;

[0007] The wiring assembly includes a first terminal, a second terminal, a first wire, a second wire, and four sliding rheostats. The sliding rheostats are fixed in the housing by a bracket. Each sliding rheostat is equipped with a slider. The first terminal and the second terminal are used to connect to different power supply lines. Each sliding rheostat is connected to the first terminal and the second terminal through the first wire and the second wire to form an independent branch. The independent branches are connected in series to form the total power supply circuit.

[0008] The adjustment assembly includes a connecting pipe, pistons matching the number of sliding rheostats, a first magnetic block, and a connecting rod. The connecting pipe is filled with lubricating fluid. Each piston is sealed and slidably disposed in the connecting pipe. Each piston is fixedly connected to the first magnetic block and fixedly connected to the slider of the corresponding sliding rheostat through the connecting rod.

[0009] The drive assembly includes a motor, a screw, a moving block, a vertical rod, a second magnetic block, a cylinder, and a slide. The motor is fixed inside the housing, and its output shaft is driven by the screw. The moving block is threadedly connected to the screw, and the vertical rod is vertically fixed on the moving block. The cylinder is fixed inside the housing, and its output shaft is driven by the slide. The slide has a guide hole that matches the vertical rod. The second magnetic block is simultaneously slidably sleeved on the vertical rod and slidably connected to the slide.

[0010] Furthermore, a bracket is fixedly connected to the housing, and the bracket is positioned between each set of first and second terminals. The connecting pipe, piston, and first magnetic block are located on one side of the partition, and the second magnetic block of the drive assembly is located on the other side of the partition. The first and second magnetic blocks are arranged with opposite poles facing each other. The movement of the second magnetic block attracts the corresponding first magnetic block, causing the piston to slide. In turn, the connecting rod drives the slider to move to adjust the resistance value of the sliding rheostat, thereby adjusting the current ratio of each energy supply branch.

[0011] Furthermore, there are four sliding rheostats, and four pistons, four first magnetic blocks, and four connecting rods, with the four pistons evenly distributed inside the connecting pipe.

[0012] Furthermore, the connecting pipe is a rigid sealed pipe made of a non-magnetic material.

[0013] Furthermore, both the first and second magnetic blocks are permanent magnets, and their attraction force is greater than the damping force of the lubricating fluid on the piston.

[0014] Furthermore, the vertical rod and the movable block are integrally formed, the cross-section of the vertical rod is rectangular, and the second magnetic block has a rectangular sliding hole that matches the vertical rod.

[0015] Furthermore, the guide hole on the carriage is an elongated hole, and the length direction of the guide hole is consistent with the length direction of the screw.

[0016] Furthermore, the lubricant is an insulating heat-conducting oil, the motor is a servo motor, and the cylinder is a miniature cylinder.

[0017] Furthermore, the box body is provided with a box door, which is hinged to the box body via a hinge, and the box door is provided with an observation window.

[0018] The significant advantages of this invention compared to existing technologies are:

[0019] Firstly, in this invention, the device can precisely regulate the energy supply ratio of different areas after the grid-based reconstruction of the distribution network through independent wiring branches and sliding rheostat adjustment units. Combined with load forecasting results, it can quickly respond to load change demands in different grid areas, achieving differentiated optimization with "one policy per area," and effectively improving the distribution network's adaptability to load distribution differences.

[0020] Secondly, this invention employs a magnetic adsorption transmission method. A driving component moves the second magnetic block, quickly attracting the first magnetic block in the corresponding area and driving the piston to slide, thereby adjusting the resistance value of the sliding rheostat. Compared to traditional mechanical transmission, magnetic transmission eliminates direct contact, reducing transmission losses and mechanical wear, and significantly improving the adjustment response speed. Simultaneously, the coordinated drive of the motor and cylinder enables precise positioning of the second magnetic block, ensuring the accuracy of the sliding rheostat resistance adjustment and guaranteeing the accuracy of energy supply ratio adjustment.

[0021] Thirdly, in this invention, the lubricating fluid filling the connecting pipe works in concert with multiple pistons. When the energy supply ratio of a certain branch is adjusted, other branches can achieve reverse coordinated adjustment through pressure. Furthermore, the movement distance of a single piston is equal to the sum of the movement distances of the other pistons, ensuring that the resistance changes of each branch compensate for each other and guaranteeing a stable total power supply current. This feature effectively avoids voltage fluctuations in the distribution network caused by adjustments in a single branch, improving the stability and reliability of the distribution network operation.

[0022] Fourthly, in this invention, the entire device is integrated into the housing, and the transmission components and adjustment components are isolated by a partition to avoid mutual interference. The observation window on the housing door allows staff to monitor the operating status of the internal components in real time, reducing the difficulty of operation and maintenance. At the same time, the connection structure of each component is simple, using non-magnetic connecting pipes and insulating heat-conducting oil lubricant, which improves the insulation performance and service life of the device and reduces operation and maintenance costs.

[0023] Fifthly, in this invention, the device, through its multi-branch design, can connect to various types of energy supply lines, and can quickly adjust the power supply ratio according to the sufficiency of each energy source. In scenarios with large-scale distributed energy integration, it can prioritize increasing the power supply ratio of sufficient energy sources, reduce the consumption of traditional energy, effectively improve energy utilization efficiency, and contribute to energy conservation, emission reduction, and green development of the power distribution network.

[0034] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0035] This invention provides an improved distribution network differentiation optimization device based on load forecasting and grid-based reconfiguration. The technical solution of this invention is as follows:

[0036] like Figures 1-7 As shown, the distribution network differentiation optimization device based on load forecasting and grid reconfiguration includes a box 1, a wiring assembly 3, a regulating assembly 4, a drive assembly 5, and a partition 6. The partition 6 is set inside the box 1, dividing the inside of the box 1 into two independent areas. The box 1 is made of aluminum alloy to ensure protection and installation compatibility. The partition 6 is non-magnetic and insulated and is centrally located to achieve independent anti-interference for the two cavities.

[0037] The wiring assembly 3 includes a first terminal 31, a second terminal 32, a first wire 33, a second wire 34, and four sliding rheostats 36. The sliding rheostats 36 are fixed inside the housing 1. Each sliding rheostat 36 is equipped with a slider 37. The first terminal 31 and the second terminal 32 are used to connect to different energy power supply lines. Each sliding rheostat 36 is connected to the first terminal 31 and the second terminal 32 through the first wire 33 and the second wire 34 to form an independent branch. The independent branches are connected in series to form the total power supply circuit. The bracket 35 is set between each group of first terminals 31 and second terminals 32. The terminals are made of copper plated with gold to prevent oxidation. The sliders 37 are made of copper alloy to improve conductivity and realize the stable access of multiple energy sources.

[0038] The adjustment assembly 4 includes a connecting pipe 41, pistons 42 matching the number of sliding rheostats 36, a first magnetic block 43, and a connecting rod 44. The connecting pipe 41 is filled with lubricating fluid 45. Each piston 42 is sealed and slidably disposed in the connecting pipe 41. Each piston 42 is fixedly connected to the first magnetic block 43 and fixedly connected to the slider 37 of the corresponding sliding rheostat 36 through the connecting rod 44. The connecting pipe 41 is made of stainless steel for sealing and fixing, and the pistons 42 are made of fluororubber to achieve sealing separation and smooth sliding.

[0039] The drive assembly 5 includes a motor 51, a screw 52, ​​a moving block 53, a vertical rod 54, a second magnetic block 55, a cylinder 56, and a slide 57. The motor 51 is fixed inside the housing 1, and its output shaft is connected to the screw 52. The moving block 53 is threadedly connected to the screw 52, ​​and the vertical rod 54 is vertically fixed on the moving block 53. The cylinder 56 is fixed inside the housing 1, and its output shaft is connected to the slide 57. The slide 57 has a guide hole that matches the vertical rod 54. The second magnetic block 55 is simultaneously slidably sleeved on the vertical rod 54 and slidably connected to the slide 57.

[0040] In this embodiment, a bracket 35 is fixedly connected to the housing 1. The bracket 35 is disposed between each group of first terminals 31 and second terminals 32. The connecting pipe 41, piston 42, and first magnetic block 43 are located on one side of the partition 6. The second magnetic block 55 of the drive assembly 5 is located on the other side of the partition 6. The first magnetic block 43 and the second magnetic block 55 are arranged with opposite poles facing each other. The movement of the second magnetic block 55 attracts the corresponding first magnetic block 43, driving the piston 42 to slide. Then, the connecting rod 44 drives the slider 37 to move to adjust the resistance value of the sliding rheostat 36, thereby realizing the adjustment of the current ratio of each energy power supply branch.

[0041] In this embodiment, there are four sliding rheostats 36, and four pistons 42, four first magnetic blocks 43 and four connecting rods 44. The four pistons 42 are evenly distributed in the connecting pipe 41.

[0042] In this embodiment, the connecting pipe 41 is a rigid sealed pipe, and its material is a non-magnetic material.

[0043] In this embodiment, both the first magnetic block 43 and the second magnetic block 55 are permanent magnets, and their attraction force is greater than the damping force of the lubricating fluid 45 on the piston 42.

[0044] In this embodiment, the vertical rod 54 and the movable block 53 are integrally formed. The cross-section of the vertical rod 54 is rectangular, and the second magnetic block 55 has a rectangular sliding hole that matches the vertical rod 54.

[0045] In this embodiment, the guide hole on the carriage 57 is an elongated hole, and the length direction of the guide hole is consistent with the length direction of the screw 52.

[0046] In this embodiment, the lubricant 45 is an insulating heat-conducting oil, the motor 51 is a servo motor, the cylinder 56 is a miniature cylinder, the cylinder 56 is a miniature cylinder of model CDJ2B16, and the motor 51 is a servo motor of model SG-M10.

[0047] In this embodiment, the enclosure 1 is provided with an enclosure door 2, which is hinged to the enclosure 1 via a hinge. The enclosure door 2 is provided with an observation window, through which staff can observe the operating status of components such as the sliding rheostat 36 and the connecting pipe 41 in real time. Daily inspections can be completed without opening the enclosure door 2, reducing the difficulty of operation and maintenance. The enclosure door 2 is equipped with stainless steel hinges and sealing strips to achieve sealing protection. The tempered glass observation window is adapted to the space inside the enclosure 1, which facilitates inspection and reduces the difficulty of operation and maintenance.

[0048] The specific working method is as follows: In a multi-energy complementary system, different energy sources occupy different proportions. When a certain energy source is sufficient, it can be used as the main source of power supply, and the proportion of other energy sources can be reduced. The first terminal 31 and the second terminal 32 on this device are used to connect to the lines of different energy sources. By changing the resistance value of each sliding rheostat 36 connected to the circuit, the current of different energy sources is changed. In the end, the total current remains unchanged, and only the current magnitude of each source is changed.

[0049] For example, when the power supply comes from four different energy sources, four sliding rheostats 36 are installed in the housing 1. Each sliding rheostat 36 is connected to the circuit through the first wire 33, the second wire 34, the first terminal 31, and the second terminal 32. Finally, the four circuits are connected in series to supply power together. When the power supply of a certain energy source is sufficient, the resistance of the corresponding sliding rheostat 36 can be reduced, thereby increasing the supply current of the circuit. This can be achieved by moving the slider 37 on the sliding rheostat 36 away from the connecting pipe 41. Since each slider 37 is connected to the piston 42 in the connecting pipe 41 through the connecting rod 44, the corresponding connecting rod 44 and slider 37 can be moved by moving the piston 42, thereby adjusting the resistance of the sliding rheostat 36.

[0050] The slider 37 on the sliding rheostat 36 can be moved by starting the motor 51 and the cylinder 56. First, the cylinder 56 is started, causing its output shaft to move up and down, which drives the slide 57 to move. When the slide 57 moves, the second magnetic block 55 on it moves up and down accordingly. When the motor 51 is started, the screw 52 can be rotated forward or backward by the forward and reverse rotation of the motor 51, so that the moving block 53 connected to it by the thread can slide in the horizontal direction. When the moving block 53 moves, the vertical rod 54 moves accordingly. Since the second magnetic block 55 is not only slidably connected to the vertical rod 54, but also slides on the slide 57, the second magnetic block 55 can also move to any position on the partition 6 when the motor 51 and the cylinder 56 drive the moving block 53 and the slide 57 to move respectively.

[0051] When the second magnetic block 55 moves on the partition 6, according to the position of the second magnetic block 55, a certain first magnetic block 43 in the connecting pipe 41 on the other side of the partition 6 will be attracted by the second magnetic block 55, thereby driving the piston 42 to move accordingly. This causes the connecting rod 44 to move with the piston 42, thereby adjusting the position of the slider 37 on the corresponding sliding rheostat 36 to reduce the resistance of the sliding rheostat 36. Therefore, the current in the circuit corresponding to the sliding rheostat 36 will increase, thereby increasing the power supply ratio of the energy corresponding to this circuit. Since the connecting pipe 41 is filled with lubricating fluid 45, under the action of pressure, when the first piston 42 moves under the movement of the first magnetic block 43 and the second magnetic block 55, the pressure in the connecting pipe 41 will cause the other three pistons 42 to move towards the first magnetic block 43 and the second magnetic block 55. As the pistons move in the opposite direction, the resistance of the other three sliding rheostats 36 will increase. That is, when the power supply ratio of one circuit increases, the power supply ratio of the other three circuits will decrease. Since the four pistons 42 are all in the connecting pipe 41, the moving distance of the actively moving piston 42 is equal to the sum of the moving distances of the other three passively moving pistons 42. Therefore, the decrease in resistance of the sliding rheostat 36 is equal to the sum of the increases in resistance of the other three sliding rheostats 36. Therefore, as long as the four sliding rheostats 36 are connected in series in the corresponding circuits, it can be ensured that when the power supply of one circuit increases, the power supply of the other three circuits decreases by a similar amount, but the sum of the total power supply current of the four circuits is always equal.
