Description

Technical Field

[0001] The present invention relates to the field of energy technology, and in particular to a method and device for determining electricity price subsidies and a non-volatile storage medium. Background Art

[0002] The rise of facility agriculture and agricultural processing industries in rural areas has led to a significant increase in electricity consumption. However, due to historical reasons, rural power grids have less investment, resulting in poor power supply reliability. In order to ensure modern agricultural electricity consumption, it is necessary to increase investment in rural power grid infrastructure. However, the electricity load rate in rural areas is low and the total electricity consumption is small. Therefore, the unit electricity investment cost of rural power transmission and distribution facilities is too high, resulting in the inability to effectively recover the investment in rural power transmission and distribution facilities, and it is necessary to rely more on cross-electricity price subsidies. In the relevant technology, it is not taken into account that rural areas have the advantage of building an energy Internet. Rural areas can take advantage of convenient natural environmental conditions and use new energy power generation and energy storage to compensate for the power supply of the power grid.

[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0027] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0028] Energy Internet can be applied in rural areas. It refers to the use of information technology, Internet of Things technology and other means to integrate and manage the dispersed and fragmented energy resources in rural areas to achieve efficient use and sharing of energy. By building new energy power generation, energy storage and other facilities, rural energy can be monitored, dispatched and managed to achieve optimal allocation and flexible dispatch of energy, and improve energy utilization efficiency and energy supply reliability.

[0029] Cross-subsidy electricity tariff subsidy refers to the practice in the power industry of charging certain users or regions electricity prices higher than the cost, and then using the proceeds to subsidize the electricity prices of other users or regions. This subsidy system aims to solve the problem that some users or regions cannot afford high-cost electricity prices. In some rural areas, due to high infrastructure construction costs, low electricity consumption, and low user payment ability, the actual electricity price often cannot cover the power supply cost. In order to guarantee the electricity demand in rural areas, higher electricity prices are charged to urban or industrial users, and the proceeds are used to subsidize the electricity prices of rural users.

[0030] In response to the problem, an embodiment of the present invention provides an embodiment of a method for determining cross-electricity price subsidies. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 1 is a flow chart of a method for determining a cross-price subsidy according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0032] Step S102, determining a target area for power grid construction, and collecting geographical information and estimated maximum power consumption of the target area;

[0033] It is understandable that power grid construction is needed in the target area, but there is currently a lack of power supply capacity. The geographical location and environmental factors of the target area affect the difficulty of infrastructure construction to supply power to it. Therefore, it is necessary to collect geographical information of the target area and the required maximum predetermined power consumption.

[0034] Optionally, the target area may be a rural area.

[0035] In an optional embodiment, the estimated maximum power consumption of the target area is collected, including: determining other areas indicated by the geographical information, and the historical maximum power consumption of other areas in the historical period, wherein the other areas are different areas in the same region as the target area; obtaining the existing demand power consumption of the target area; and obtaining the estimated maximum power consumption based on the maximum of the historical maximum power consumption and the demand power consumption.

[0036] It is understandable that the estimated maximum power consumption can be determined with the help of the historical maximum power consumption of other regions. Since other regions are in the same region as the target region, their power consumption has a certain guiding role for the target region. The historical maximum power consumption of other regions in the historical period is determined, and the power grid to be built must at least be able to support the historical maximum power consumption. The target area may already have some power demand, and the power demand can be counted. Compare the power demand and the historical maximum power consumption, and get the largest one of the two, so that the power grid to be built has sufficient power support capacity, and then get the estimated maximum power consumption.

[0037] It should be noted that since different regions are often geographically close and are affected by similar climate, environment, economic development and other factors, their electricity demand may have certain similarities. The structure of electricity demand is similar, such as the proportion and development level of agriculture, industry, etc., which will lead to relatively stable electricity demand in different regions and similarities in some aspects. And the types of electricity equipment are similar. In the same region, the types of electricity equipment in different regions may be similar, such as household electricity, agricultural electricity, public facility electricity, etc. The type and quantity of these electricity equipment have a great impact on electricity consumption, so the electricity consumption in different regions may have certain similarities.

[0038] Optionally, other regions can be regions with greater similarity to the target region, and adjustments can be made according to the percentage of electricity consumption in other regions or according to the population to obtain the historical maximum electricity consumption that matches the target region. Further, statistical modeling methods, such as regression analysis, time series analysis, etc., can also be used to establish a prediction model. By using the electricity consumption of the reference area as an independent variable to predict the electricity consumption of the target area, it is necessary to consider some relevant factors, such as population, economic development level, seasonal changes, etc., and select a suitable model for prediction, and obtain the expected maximum electricity consumption based on the prediction.

[0039] Step S104, determining a first unit electricity cost of power supply from the power grid based on the regional information and the estimated maximum electricity consumption;

[0040] It can be understood that the geographical information of the target area can characterize the difficulty of power grid construction. The more difficult it is, the higher the cost will be. The power grid needs to be able to cover the predetermined maximum power consumption of the target area. The greater the required capacity of the transmission and transformation lines in the power grid, the higher the cost will be. Through processing, the first unit electricity cost of power supply by the power grid alone can be determined.

[0041] In an optional embodiment, a first unit electricity cost of power supply by the power grid is determined based on the regional information and the expected maximum power consumption, including: determining the power transmission length indicated by the regional information; determining the first power transmission and transformation line capacity for the target area based on the expected maximum power consumption; determining the first cost of power grid construction for the target area based on the power transmission length and the first power transmission and transformation line capacity; determining the first unit electricity cost based on the first cost and the expected total power consumption within the life of the power transmission and transformation equipment of the power grid.

[0042] It can be understood that the geographical information of the target area can indicate the length of power transmission to it, and the capacity of the first power transmission and transformation line for the target area can be determined based on the predetermined maximum power consumption that represents the maximum demand. The target area may have problems such as complex geographical environment, dispersed population, long power supply distance, incomplete infrastructure, etc., and has higher cost problems than towns. It is necessary to determine the first cost of power grid construction in the target area based on the power transmission length and the capacity of the first transmission and transformation line. According to the first cost and the expected total power consumption within the life of the power transmission and transformation equipment of the power grid, the first unit electricity cost is determined.

[0043] Optionally, the ratio of the first cost to the expected total electricity consumption is the first unit electricity cost.

[0044] It should be noted that the target area may be located in an area with complex terrain, many mountainous and hilly areas, and it is difficult to lay power lines. A large amount of terrain modification and mountain climbing are required, which increases the difficulty and cost of construction. The target area has a dispersed population, many household registration points, and a wide coverage of the power grid. A large number of power transmission and distribution lines and equipment need to be laid, which increases the length of the line and the number of equipment, thereby increasing the cost. The power supply distance is generally long, and the power transmission loss is large. It is necessary to increase the cross-section of the transmission line to ensure the quality of power supply, which increases the cost of the line. There may also be relatively weak infrastructure. The construction of power transmission and distribution facilities requires the construction of roads and bridges at the same time. The construction costs of these infrastructures will also be included in the cost of power facilities. Power equipment needs periodic maintenance to ensure stable and safe power use. Due to the vast area of ​​rural areas, the cost of maintaining and managing power facilities is high, including inspection, maintenance, and equipment replacement costs. These costs will also be reflected in the first cost of power grid construction.

[0045] Step S106, determining the power supply compensation amount of the energy internet, wherein the energy internet is to be constructed in the target area and is used to combine with the power grid to supply power to the target area;

[0046] It can be understood that the energy Internet is used to coordinate power supply with the power grid in the target area. Determining the power supply compensation amount of the energy Internet can represent the reduction in the amount of electricity obtained from the power grid.

[0047] Optionally, the Energy Internet can realize the coordinated power supply between different energy systems. When the target area is coordinated with the power grid for power supply, the energy supply of the target area can be monitored, controlled and optimized through the intelligent energy management system. Real-time monitoring of energy production and consumption, and energy dispatch according to demand, so that energy supply and demand are balanced.

[0048] Optionally, in addition to supplementing the power supply of the power grid to the target area, the energy Internet can also establish a two-way power flow mechanism between the target area and the power grid. When the energy supply of the target area is insufficient, it can obtain electricity from the power grid for supplementation. When the energy production of the target area exceeds the demand, the excess electricity can be transmitted to the power grid.

[0049] In an optional embodiment, determining the power supply compensation amount of the energy Internet includes: when the energy Internet includes a new energy power generation sub-network and a distributed energy storage sub-network, determining the power generation corresponding to the new energy power generation sub-network and the amount of storage energy corresponding to the distributed energy storage sub-network; and determining the power supply compensation amount based on the power generation and the amount of storage energy.

[0050] It can be understood that the energy Internet can include sub-networks with two different functions: power generation and energy storage. When the energy Internet includes a new energy power generation sub-network and a distributed energy storage sub-network, the power generation corresponding to the new energy power generation sub-network and the storage capacity corresponding to the distributed energy storage sub-network can be determined. By balancing the power generation and energy output, the power supply compensation provided by the overall energy Internet can be determined.

[0051] In an optional embodiment, the new energy power generation sub-network includes at least one of the following: a photovoltaic power generation sub-network, a wind power generation sub-network; the distributed energy storage sub-network includes at least one of the following: a battery energy storage sub-network, a capacitor energy storage network, and an agricultural machinery energy storage sub-network.

[0052] It can be understood that the new energy generation sub-network can be a photovoltaic power generation sub-network and / or a wind power generation sub-network, and the distributed energy storage sub-network can be a battery energy storage sub-network and / or a capacitor energy storage network and / or an agricultural machinery energy storage sub-network.

[0053] It should be noted that in the energy internet, the new energy generation sub-network and the distributed energy storage sub-network can be used to shift peaks and fill valleys. Photovoltaic generation sub-networks are built in rural areas, and solar photovoltaic modules are used to convert solar energy into electrical energy. These photovoltaic modules can be distributed in farmland, farmhouses, agricultural greenhouses and other places, using the vast land resources in rural areas to generate electricity. Wind power generation sub-networks can be set up in the same way. Since new energy generation has periodic changes, the photovoltaic generation sub-network and the distributed energy storage sub-network can be used to store the electricity generated by photovoltaic power generation and wind power generation during the day for use at night or during low-load periods. In addition, in rural areas, some agricultural machinery, such as electric tractors, can be used as energy storage devices. When agricultural machinery is not needed, it can be connected to the energy storage system and the stored electrical energy can be stored in the battery of the electric tractor. When electricity is needed, the electric tractor can be connected to the power grid or other electrical equipment, and the stored electrical energy can be released through the inverter for power supply.

[0054] Optionally, through the intelligent energy management system, centralized dispatching and control of photovoltaic power generation sub-networks, wind power generation sub-networks, battery energy storage sub-networks, capacitor energy storage sub-networks, and agricultural machinery energy storage sub-networks can be achieved. According to the load of the power grid or the peak and valley conditions of electricity prices, the stored electric energy can be released during peak periods to meet electricity demand and reduce the load on the power grid. During the valley period, the distributed energy storage sub-network can be used for charging, and the charging source can be the new energy power generation sub-network for use during the next peak period. It can achieve effective utilization of energy and optimize the balance between supply and demand, and promote the efficiency of energy use in the energy Internet and the power grid.

[0055] Step S108, determining a second unit electricity cost of the combined power supply of the power grid and the energy internet based on the power supply compensation amount and the estimated maximum power consumption;

[0056] It can be understood that the second unit electricity cost can be determined based on the power supply compensation amount and the estimated maximum power consumption. Since the second unit electricity cost is the power supply of the power grid and the energy Internet in cooperation with each other, the electricity obtained from the power grid is relatively small, and the construction cost requirements for the transmission and transformation lines are reduced. The second unit electricity cost will be lower than the first unit electricity cost.

[0057] In an optional embodiment, based on the power supply compensation amount and the estimated maximum power consumption, a second unit power consumption cost of the combined power supply of the power grid and the energy Internet is determined, including: using the power supply compensation amount to compensate for the estimated maximum power consumption to obtain the compensated estimated maximum power consumption, wherein the compensated estimated maximum power consumption is less than the estimated maximum power consumption; determining the second power transmission and transformation line capacity for the target area based on the compensated estimated maximum power consumption; determining the second cost of power grid construction for the target area based on the power transmission length and the second power transmission and transformation line capacity, wherein the power transmission length is obtained by indicating the geographical information; determining the second unit power consumption cost based on the second cost and the expected total power consumption within the life of the power transmission and transformation equipment of the power grid.

[0058] It can be understood that the estimated maximum power consumption provided by the power grid alone will be lower than before compensation after being compensated by the power supply compensation amount. The estimated maximum power consumption after compensation is used to determine the capacity of the second transmission and transformation line for the target area. Since the estimated maximum power consumption after compensation is reduced, the capacity of the second transmission and transformation line will also become smaller, and the corresponding construction cost of the transmission and transformation facilities will also be reduced. The second cost of power grid construction in the target area can be determined based on the power transmission length and the capacity of the second transmission and transformation line. It should be noted that the second cost will be lower than the first cost. According to the second cost and the expected total power within the life of the power transmission and transformation equipment of the power grid, the second unit electricity cost can be obtained.

[0059] Optionally, the ratio of the second cost to the expected total electricity consumption is the second unit electricity cost.

[0060] In an optional embodiment, the second unit electricity cost is determined based on the second cost and the expected total electricity consumption within the life of the power transmission and transformation equipment of the power grid, including: determining the third cost of constructing the energy Internet in the target area; determining the second unit electricity cost based on the second cost, the third cost, and the expected total electricity consumption within the life of the power transmission and transformation equipment of the power grid.

[0061] It can be understood that, assuming that the target area has not built an energy Internet, in order to avoid setting the target electricity price too low, it is also necessary to add the third cost of building the energy Internet. The second unit electricity cost is determined based on the second cost, the third cost, and the expected total electricity consumption.

[0062] Step S110: determining a target electricity price based on the first unit electricity cost and the second unit electricity cost.

[0063] It can be understood that, based on the first unit electricity cost and the second unit electricity cost, a target electricity price can be determined to indicate power supply processing for the target area.

[0064] In an optional embodiment, a target electricity price is determined based on a first unit electricity cost and a second unit electricity cost, including: determining the difference between the first unit electricity cost and the second unit electricity cost; using the difference to correct a predetermined initial cross-price subsidy value to obtain a target cross-price subsidy value, so that the target cross-price subsidy value is less than the initial cross-price subsidy value; and obtaining a target electricity price based on the target cross-price subsidy value.

[0065] It can be understood that the first unit electricity cost is greater than the second unit electricity cost, and the difference is obtained by subtracting the second unit electricity cost from the first unit electricity cost. The difference can be regarded as a reduction in the predetermined initial cross-price subsidy value, and then the target cross-price subsidy value is obtained. The target cross-price subsidy value is used to determine the target electricity price for the target area.

[0066] Through steps S102 to S110, the purpose of reducing cross-price subsidies in electricity price setting by providing power supply compensation based on rural energy Internet can be achieved, and the technical effect of improving the accuracy of electricity price setting can be realized, thereby solving the technical problem of unsatisfactory accuracy of electricity price setting existing in related technologies.

[0067] Based on the embodiment and the optional embodiment, the present invention proposes an optional implementation mode, which is specifically the following steps:

[0068] Step S1: A power grid needs to be constructed in the target area. The capacity of the first power transmission and transformation line for the target area is determined according to the estimated maximum power consumption. The first cost of the power grid construction for the target area is determined according to the first power transmission and transformation capacity and the power transmission length.

[0069] Step S2, determining the expected total electricity quantity within the service life of the power transmission and transformation equipment of the power grid, and then obtaining the ratio of the first cost to the expected total electricity quantity as the first unit electricity cost.

[0070] Step S3, rural areas can take advantage of convenient natural environmental conditions and use new energy generation and energy storage to compensate for power supply to the power grid. The energy Internet is used to coordinate power supply with the power grid in the target area, and the power supply compensation amount of the energy Internet is determined. According to the power supply compensation amount and the expected maximum power consumption, the expected maximum power consumption after compensation can be determined. Based on the power transmission length and the capacity of the second transmission and transformation line, the second cost of power grid construction in the target area is determined. The energy Internet includes a photovoltaic power generation sub-network, a battery energy storage sub-network, and an agricultural machinery energy storage sub-network.

[0071] Step S4: The ratio of the second cost to the expected total electricity consumption is the second unit electricity cost. The second cost will be lower than the first cost.

[0072] Step S5, subtract the second unit electricity cost from the first unit electricity cost to obtain a difference, reduce the predetermined initial cross-price subsidy value by the difference, obtain a target cross-price subsidy value, and obtain a target electricity price for the target area.

[0073] The optional implementation method can achieve at least the following effects: by measuring the unit electricity cost before and after the construction of the energy Internet, the subsidy for grid construction in rural areas can be effectively reduced, making the electricity price setting in the region more accurate, while also improving the use of clean energy in rural areas and improving the cleanliness, autonomy and reliability of energy use.
