Description

Technical Field

[0002] With the proposal and implementation of the national carbon peak and carbon neutrality policies, traditional thermal power plants are slowly being replaced by new clean energy sources. However, clean energy generation methods such as wind power, photovoltaic power generation and hydropower generation are greatly affected by natural factors, so the power generation often fluctuates greatly. In addition, the power consumption in the power market also changes with the seasons, working days and non-working days, and even the time of morning and evening. Therefore, pumped storage power stations have become very important. Pumped storage power stations can convert the potential energy of water into electrical energy. When the power consumption is at a low point, the pumped storage power station first uses the surplus electricity in the power grid to pump the water from the lower reservoir to the upper reservoir for storage. This process converts electrical energy into the potential energy of water. When the peak of power consumption comes, the water in the upper reservoir is released, and the water flows down to drive the turbine to generate electricity. This process converts the potential energy of water into electrical energy.

[0036] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings.

[0037] Application Overview

[0038] As my country proposes to achieve the "dual carbon" goal by 2060, it is imperative to reduce the use of traditional fossil energy. In the field of electricity, fossil energy can ensure the stable output of electricity, so it plays an important role in the safe operation of my country's electricity. Although the installed capacity of new energy power generation equipment has grown rapidly in my country in recent years, its power generation efficiency is unstable. For example, photovoltaic power generation is limited by sunshine, wind power generation depends on wind power, and conventional hydropower generation is closely related to rainfall; at the same time, the production electricity consumption of society and the people's daily electricity consumption are related to the economy, climate, etc., and their electricity consumption also fluctuates.

[0039] Pumped-storage power stations can convert electricity into water potential energy when there is a surplus of electricity, and can convert water potential energy into electrical energy when there is a shortage of electricity. Therefore, as a facility that can both store energy and generate electricity and convert it into electrical energy, the importance of pumped-storage power stations is self-evident. However, the existing pumped-storage power stations have single scheduling considerations and simple control, and cannot maximize the efficiency of the power grid.

[0040] In response to the above technical problems, the overall idea of ​​the technical solution provided by this application is as follows:

[0041] An embodiment of the present application provides a planning and scheduling method for a pumped-storage power station, the method comprising: obtaining information on power generation equipment and power consumption types of the power grid; obtaining historical power generation data and historical power consumption data of the power grid within a predetermined time range; predicting and generating power generation and power consumption trends of the power grid based on the historical power generation data and historical power consumption data of the power grid, wherein the power generation trend of the power grid includes power generation trends of various types of power generation equipment, and the power consumption trend includes power consumption trends of various types of power consumption; generating a planning and scheduling scheme for the pumped-storage power station based on the power generation and power consumption trends of the power grid; and performing work scheduling of the pumped-storage power station based on the planning and scheduling scheme of the pumped-storage power station.

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] Embodiment 1

[0044] like Figure 1 As shown, an embodiment of the present application provides a planning and scheduling method for a pumped storage power station, the method comprising:

[0045] Obtain information about power grid power generation equipment and electricity usage types.

[0046] Exemplarily, the power grid power generation equipment of this embodiment includes: thermal power plants, hydropower stations, wind power stations, and photovoltaic power stations. Of course, the power generation equipment targeted by the embodiment of the present application can also adopt other forms of power generation, such as nuclear energy, which is not limited by the embodiment of the present application. At present, the main power generation equipment of my country's power grid is mainly thermal power plants and hydropower stations, and the installed capacity of wind power stations and photovoltaic power stations is also growing rapidly, but the above equipment can only generate electricity but cannot store energy. At present, photovoltaic and wind power generation are also equipped with large-capacity energy storage batteries, but their equipment costs are high, and there is still an environmental pollution problem after long-term use of batteries. Pumped storage power stations are of great significance for electricity "peak shaving and valley filling" because they can both store energy and generate electricity, and their installed capacity has been growing rapidly. The electricity consumption type information of this embodiment simply includes industrial electricity, commercial electricity, and residential electricity. Different electricity consumption priorities can be set according to their load types, such as core loads, important loads, general loads, etc. When electricity is scarce, different electricity consumption priorities can be set according to the importance and type of loads.

[0047] Obtain historical power generation data and historical power consumption data of the power grid within a predetermined time range.

[0048] Specifically, the total historical power generation of the power grid within the predetermined time range is:

[0049]

[0050] Among them, W lf Indicates the total historical power generation of the power grid within a predetermined time range, W i It represents the total historical power generation of the i-th power generation equipment within a predetermined time range.

[0051] The total historical electricity consumption of the power grid within the predetermined time range is:

[0052]

[0053] Among them, W ly Indicates the total historical power consumption of the power grid within a predetermined time range, W j It represents the total historical electricity consumption of the jth type of electrical equipment within a predetermined time range.

[0054] According to different regions, different seasons, and different main power generation methods, a predetermined time range can be set. For example, it can be predicted by the hour every day, or it can be predicted on a daily basis, or it can be predicted on a weekly or monthly basis. Of course, it is understandable that the smaller the predetermined time range, the higher the accuracy of the final adjustment, but the more data required for calculation, and the more frequent the planning and scheduling. In addition, since the startup and operation of a pumped storage power station takes from tens of seconds to several minutes, the smaller the predetermined time range, the better. It also needs to match the actual situation of the target location. The power generation data W retrieved from the historical period of the power grid lf Including the historical data of power generation of different types of power generation equipment mentioned above i , these data include thermal power generation, hydropower generation, wind power generation and photovoltaic power generation. The power consumption data of the power grid in the historical period is retrieved ly Including power consumption data of different types and load priorities of electrical equipment W j .

[0055] It is necessary to preprocess the electricity consumption data to eliminate the impact of different data sources for unified analysis, eliminate abnormal data, and then extract key features from the preprocessed data, such as the impact of changes on electricity consumption every day, week, day, night, weekdays, holidays, different seasons, different weather, etc., and then perform trend analysis on the electricity consumption data.

[0056] According to the historical power generation data W of the power grid lf And historical electricity consumption data W ly Predict the power generation W of the power grid yf And power consumption W yy Trend, where the power generation W of the power grid yfThe trends include power generation trends of various types of power generation equipment, and the power consumption trends include power consumption trends of various types of power consumption.

[0057] After preprocessing the data, the power generation W of different power generation equipment in the historical period can be i Similarly, the historical power consumption W of loads of different types and priorities can be used to predict the power generation trend of the power grid. j Trend forecasting can be used to obtain the subsequent power consumption trend of the power grid.

[0058] A planning and dispatching scheme for the pumped-storage power station is generated according to the power generation and power consumption trends of the power grid.

[0059] By comparing the difference between the power generation and power consumption of the power grid in the same period, it is possible to predict whether the power grid as a whole is in a power shortage or power surplus within the time range. In simple terms, if there is a power surplus, the pumped storage power station can pump the water from the lower reservoir to the upper reservoir through a water pump for storage, so that when there is a power shortage, the discharge valve of the upper reservoir can be opened to use the drop between the upper and lower reservoirs to drive the turbine to rotate, thereby converting the potential energy of the water into electrical energy for use by the power load in the power grid. In actual operation, there are many factors that affect the adjustment of the working state of the pumped storage power station. Different regions, different seasons, and even day and night have an impact on the working state of the pumped storage power station. For example: in the southwest area with abundant water resources, hydropower generation is the main source, and precipitation in different seasons has a great impact on water flow. Pumped storage power stations are mainly used for energy storage during the flood season and for power generation during the dry season. Xinjiang and coastal areas have better wind resources, and wind power generation is more important for local power supply. Pumped storage power stations need to pay attention to the wind strength. When the wind is strong, they can store energy, and when the wind is weak, they can generate electricity. In places with sufficient sunlight, photovoltaic power generation is an important source of electric energy. Different weather conditions have a great impact on the efficiency of photovoltaic power generation. Photovoltaic power generation occurs during the day, but zero at night. Pumped storage power stations in this area need to be adjusted according to the weather and day and night.

[0060] The operation of the pumped-storage power station is dispatched according to the planning and dispatching scheme of the pumped-storage power station.

[0061] Based on the generated planning and scheduling scheme, the pumped storage power station drives water pumps, sluice gates, turbines and other equipment to perform corresponding operations at the preset time according to the planning and scheduling scheme.

[0062] Further, as an optimization solution of the embodiment of the present application, the historical power generation data W of the power grid is lf And historical electricity consumption data W lyThe prediction of the power generation and power consumption trends of the power grid also includes:

[0063] The forecasted meteorological data and historical meteorological data within the predetermined time range are obtained, and the power generation data and power consumption data trends of the power grid are updated and generated.

[0064] As mentioned above, climate and weather have a great impact on local power generation and electricity consumption. For example, in the southern region, due to the high temperature in summer, people use air conditioners for a long time, which can cause summer to become the peak of electricity consumption throughout the year. For areas with more developed hydropower generation, the rainy season can keep their hydropower generation at a high level for several months. Therefore, when predicting local power generation and electricity consumption within a predetermined time range, it is necessary to consider meteorological data to make the prediction data more accurate.

[0065] Furthermore, as an optimization solution of the embodiment of the present application, the historical electricity prices of the power grid in each time period are obtained. Generate a predicted electricity price for the power grid within the predetermined time range in, represents the historical electricity price of the j-th type of electrical equipment in the k-th period, It represents the predicted electricity price of the j-th type of electrical equipment in the m-period.

[0066] By analyzing multiple groups of historical electricity prices at different time periods The predicted electricity price for each period within the predetermined time range can be obtained by fitting the fluctuation curve of the historical electricity price for each period The fitting method can be a regression curve, and of course other fitting methods can also be used.

[0067] Furthermore, according to the predicted electricity price and the historical power consumption data W of the power grid ly An electrical power usage trend of the power grid is generated.

[0068] Different regions and different power generation equipment have different electricity costs. Traditional fossil energy is also affected by energy prices, while photovoltaic equipment is affected by raw material prices. At the same time, electricity prices are different in different time periods. Generally speaking, electricity prices are expensive during the day when electricity consumption is high, and cheap at night when electricity consumption is low. In addition, electricity prices in different seasons vary greatly depending on power generation costs and electricity consumption. Therefore, when specifying the planning and scheduling plan for a pumped storage power station, it is also necessary to consider the predicted electricity price within the scheduled time range. When the power grid still has redundant energy and the energy storage electricity price is lower than the power generation electricity price, electricity is used to pump water to the upper reservoir when the electricity price is low, and when the electricity price is high, electricity is generated to supply the power grid load, thereby maximizing economic benefits.

[0069] Furthermore, as an optimization solution of the embodiment of the present application, the water level data of the upper reservoir and the lower reservoir are obtained, and the pumped storage power station is dispatched according to the warning water level value. 上 , the warning water level of the upper reservoir is L 上警 , the water level of the lower reservoir is L 下 , the warning water level of the lower reservoir is L 下警 .

[0070] If there is a risk of flood disaster, when the reservoir water level is at the high warning level, that is, L 下 >L 下警 Regardless of whether the power supply of the power grid exceeds the demand or the demand exceeds the supply, flood discharge is required. In addition to opening the gates of the lower reservoir to discharge flood water, the water in the lower reservoir can also be pumped to the upper reservoir by water pumps. Of course, flood discharge and pumping can also be carried out at the same time to ensure the safety of the reservoir and its surrounding areas. Similarly, when the water level of the upper reservoir is at a high warning level, that is, L 上 >L 上警 , the gates are opened to allow water to flow into the lower reservoir through the turbines to generate electricity, and at the same time generate electricity to supply the power grid. When the water levels of both the upper and lower reservoirs are at the warning high level, the gates are opened to discharge floodwater to ensure safety.

[0071] In this embodiment, according to the historical power generation data W of different power generation equipment i and the historical power consumption data W of different power-consuming equipment j The power generation trend and power consumption trend within a predetermined time range are predicted, so as to dispatch the working state of the pumped storage power station. Moreover, this embodiment further considers the influence of factors such as weather, electricity prices in different regions and at different times, and reservoir water levels on the dispatch of the pumped storage power station, thus achieving a win-win situation in terms of social benefits and power benefits of the pumped storage power station.
