Description

Technical Field

[0001] The present invention relates to the technical field of energy utilization, and in particular to a pumped energy storage method, device and medium for high-rise buildings. Background Art

[0002] With the acceleration of global urbanization, high-rise buildings are constantly emerging in major cities. These high-rise buildings pose new challenges to energy supply and utilization. Traditional energy supply methods mainly rely on municipal power grids. However, this centralized energy supply model has certain limitations. During peak electricity demand, it is often difficult to meet the power needs of high-rise buildings, resulting in frequent voltage fluctuations and power outages, which seriously affect the normal life and work of residents and businesses in the buildings. In addition, high-rise buildings themselves have relatively low energy utilization efficiency, lack effective energy storage and management methods, and are unable to fully integrate and utilize renewable energy sources such as solar energy. This results in energy waste, increases dependence on traditional fossil fuels, and further exacerbates the tension in the energy supply.

[0003] Existing energy storage technologies also have many limitations when addressing the energy needs of high-rise buildings. For example, while battery energy storage systems can store a certain amount of electrical energy, their energy storage density is relatively low, meaning it's difficult to store enough energy to meet the electricity needs of high-rise buildings within a limited space. Batteries also pose certain safety risks and can easily cause fire accidents. Furthermore, batteries have a relatively short cycle life and require frequent replacement, increasing maintenance costs and resource consumption. Traditional pumped-storage power stations, on the other hand, have strict geographical requirements and typically rely on mountainous terrain to store and release the potential energy of water.

[0029] Monocrystalline silicon photovoltaic arrays are installed on high-rise rooftops, covering the available roof area and ensuring a solar-to-electricity efficiency of at least 22%. Monocrystalline silicon modules are selected for their high conversion efficiency and long service life, making them more adaptable to the installation conditions and space constraints of high-rise rooftops. The installed capacity is determined based on the building's electricity demand and the available roof area. A grid-connected inverter is used to convert DC power into AC power and connect it to the building's power distribution system. An elevated water tank is installed on the rooftop, with its effective capacity calculated based on the building height (H) and roof area (S) using the formula V = 0.15H·S. Underground energy storage tanks can be constructed in conjunction with the building's foundation design, excavated on the ground floor or in the underground garage area. They feature a double-layered, impermeable structure and are equipped with high-precision water level sensors for real-time water level monitoring. The pumping and discharge risers feature a dual-channel structure, with a main channel diameter of 300 mm and a balancing pipe diameter of 150 mm. The inner wall is ceramic-coated to ensure a roughness Ra ≤ 1.6 microns, reducing water flow resistance and improving system efficiency. Riser pipes are laid vertically along appropriate locations, such as the building core or stairwell, connecting the rooftop high-level water tank and the underground energy storage tank. Francis micro-hydraulic turbines, designed with a minimum efficiency of 92%, are installed near the underground energy storage tank and connected to the outlet of the pumping and discharge risers. These are then connected to a generator via piping, achieving efficient conversion of water potential energy into electrical energy.

[0030] Operational mode control: At least one year of historical output data from the building's rooftop photovoltaic array and contemporaneous meteorological information is collected. Data preprocessing, including missing value filling, outlier removal, and normalization, is performed to improve data quality. An LSTM neural network model is constructed, and the network structure, including the number of neurons in the input, hidden, and output layers, is determined. The input layer receives processed historical photovoltaic output data and meteorological information, the hidden layer uses LSTM units, and the output layer predicts photovoltaic output for the next 24 hours. The LSTM model is trained using training and test sets, using mean squared error (MSE) as the loss function. An optimization algorithm (such as Adam) is used to adjust the model's weight matrix and bias vector to ensure that the predicted results are as close to the actual values ​​as possible. During daytime hours when there is sufficient sunlight and the photovoltaic output exceeds the building's electricity load, the intelligent control system activates the pump based on the LSTM prediction results and real-time monitored electricity load data. This pump pumps water from the underground energy storage tank through the pumping and discharge risers to the rooftop high-level water tank, storing potential energy. At night or when the photovoltaic output is insufficient, the intelligent control system controls the water in the high-level water tank on the roof to flow to the underground energy storage tank through the water pumping riser, driving the micro-hydraulic turbine to generate electricity and provide power support for the building.

[0031] Safety and Maintenance: Siphon breakers and water hammer arresters are installed on the pumping and discharge risers to prevent siphoning and water hammer pressure fluctuations within the pipes, protecting the piping system and equipment and ensuring stable system operation. Water level monitoring devices are installed to monitor the water levels in the rooftop high-level water tank and underground energy storage tank in real time. When the water level exceeds the limit, an alarm signal is issued based on a formula, and power is automatically switched to the municipal grid, ensuring safe power supply to the building. A fire alarm linkage system is implemented. In the event of an emergency such as a fire, the intelligent control system automatically cuts off power to related equipment and activates firefighting equipment to prevent the incident from escalating. The photovoltaic array is regularly cleaned and inspected to remove dust, leaves, and other debris. The photovoltaic module wiring and support structure are also inspected to ensure the normal operation and power generation efficiency of the photovoltaic system. Regular maintenance is performed on equipment such as pumps and micro-hydraulic turbines, including checking their operating status, replacing worn parts, adding lubricants, and testing electrical performance, to ensure equipment reliability and efficiency. Regularly inspect and maintain hydraulic components such as pumping and discharge risers and water tanks. Check the anti-corrosion coating, joint sealing, and support stability of the pipes. Clean sediment and impurities from the water tanks to ensure the smooth operation and structural safety of the hydraulic system. Regularly update software and perform hardware maintenance on the intelligent control system, optimize control algorithms and model parameters, and ensure the system's prediction accuracy and control performance.

[0032] System optimization design and adaptive adjustment: Based on the actual height, roof area and shape of the building, combined with the building's electricity load distribution and photovoltaic power generation, use computer simulation software to optimize the design of the capacity and location of the high-level water tank on the roof, improve the efficiency and economy of the energy storage system, and reduce the impact on the building structure. According to the height of the building and the capacity of the water tank, calculate the hydraulic parameters of the water pumping and discharge risers, and select appropriate materials and structures for the water pumping and discharge risers, such as high-strength, corrosion-resistant, smooth-walled stainless steel pipes or fiberglass pipes. For super-high-rise buildings, multiple risers can be connected in parallel to reduce the pressure and water flow velocity of a single riser, reducing water flow resistance and energy loss. According to the building's water demand and head changes, select the appropriate type and specifications of micro-hydraulic turbines, optimize the selection and installation location of the micro-hydraulic turbines, ensure that the turbines have sufficient water inlet and outlet space, and reduce the impact of noise and vibration on building use. A computer simulation model of the entire pumped energy storage system is established. Through simulation analysis, the system performance indicators such as energy storage efficiency, power generation efficiency, and economy are evaluated. Based on the simulation results, the system is optimized and adjusted to improve the overall performance and efficiency of the system.

[0033] Cost accounting and benefit evaluation: Conduct a comprehensive accounting of the construction costs of the pumped storage energy storage system, including equipment procurement costs, installation and commissioning costs, civil engineering costs, design consulting costs, and other related costs, to understand the system's investment structure and provide basic data for the project's economic evaluation. Analyze the system's operating costs, including equipment maintenance costs, water resource treatment costs, personnel management costs, energy consumption costs, and other operating costs, and make statistics and forecasts based on the actual operation of the system. Calculate the system's energy-saving and emission-reduction benefits, including reduced carbon emissions and saved electricity. Based on the system's power generation and power consumption, combined with the local power grid emission factors, calculate the system's annual reduction in carbon dioxide emissions. Statistical analysis includes the amount of electricity purchased from the power grid saved by the system through photovoltaic power generation and pumped storage power generation to meet the building's electricity needs, as well as the benefits of feeding excess electricity back to the power grid. Evaluate the system's payback period and total revenue over its service life. The payback period refers to the time required for the system's revenue to cover the construction and operating costs. The total revenue over its service life refers to the net revenue after deducting the construction and operating costs from all the revenues obtained through energy conservation, emission reduction, and energy management during the system's design life. This provides an important basis for the project's investment decision-making and economic benefit analysis.
