It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] This embodiment provides an energy storage control system for a wastewater treatment plant. This system integrates photovoltaic and wind power generation and pumped storage technologies to achieve energy self-sufficiency and efficient utilization, reducing dependence on traditional thermal power; it also improves the efficiency and proportion of clean energy utilization, achieving the goals of improving quality and efficiency and reducing environmental pollution.

[0031] Specifically, such as Figure 1As shown, the wastewater treatment plant's energy storage control system includes a power generation unit, a pumped-storage unit, and an intelligent control unit. The power generation unit includes photovoltaic power generation modules 110 and wind power generation modules 120, which can generate electricity using solar energy and wind energy, respectively. The pumped-storage unit includes a first water tank 210, a second water tank 220, a pump unit, and a turbine generator unit. The vertical height of the first water tank 210 is greater than that of the second water tank 220. The second water tank 220 is used to store wastewater from the wastewater treatment plant. The pump unit is electrically connected to the power generation unit, enabling it to pump wastewater from the second water tank 220 into the first water tank 210 for energy storage. The turbine generator unit is located downstream of the first water tank 210. Wastewater flowing from the first water tank 210 into the second water tank 220 drives the turbine generator unit to generate electricity. The turbine generator unit is connected to the wastewater treatment plant's electrical facilities. Both the power generation unit and the pumped storage unit are connected to an intelligent control device to control them.

[0032] It should be noted that the upward blue solid arrows in the diagram indicate the direction of water flow, and the downward blue solid arrows indicate the direction of water flow; the dashed black arrows in the diagram indicate power transmission lines for electricity use, and the dotted black arrows indicate power transmission circuits for power generation.

[0033] Based on the above design, the photovoltaic power generation module 110 and the wind power generation module 120 can generate electricity using solar energy and wind energy respectively, using clean energy to generate electricity and reducing environmental pollution. The first water tank 210, in addition to serving as an energy storage tank, can also serve as a backup water tank to store excess sewage; the sewage from the first water tank 210 flows into the second water tank 220 to drive a turbine generator set to generate electricity. The sewage treatment plant's electrical facilities are connected to the turbine generator set, utilizing the electrical energy generated by the turbine generator set. In actual operation, when the photovoltaic power generation module 110 and the wind power generation module 120 are generating well, and the power load of the electrical facilities in the sewage treatment plant is low or predicted to be at a low power consumption period, the water pump unit is started through the intelligent control device to pump sewage from the second water tank 220 to the first water tank 210 to store excess electrical energy. When the photovoltaic power generation module 110 and the wind power generation module 120 are generating poorly, and the power load of the electrical facilities in the sewage treatment plant is high or predicted to be at a peak power consumption period, the water turbine generator unit is started through the intelligent control device, and at the same time, the sewage in the first water tank 210 is released to drive the water turbine generator unit to generate electricity to meet the power demand.

[0034] Therefore, the energy storage control system of this wastewater treatment plant integrates photovoltaic and wind power generation and pumped storage technologies to achieve energy self-sufficiency and efficient utilization, reducing dependence on traditional thermal power; it also improves the efficiency and proportion of clean energy utilization, achieving the goals of improving quality and efficiency and reducing environmental pollution.

[0035] In this embodiment, the electrical facilities in the sewage treatment plant are the same as those in the office building.

[0036] Furthermore, the wastewater treatment plant's energy storage control system also includes a transformer, which transforms the electricity generated by the hydro-generator unit before it is transmitted to the electrical equipment in the office building.

[0037] Optionally, the photovoltaic power generation module 110 includes multiple photovoltaic panels, all of which are installed on the ground within the wastewater treatment plant. Installation on vacant ground is more convenient than installation on a roof or wall. Of course, it can also be installed on the roof, exterior wall, or glass of the wastewater treatment plant as needed.

[0038] Optionally, the wind power generation module 120 and the photovoltaic power generation module 110 are arranged side by side, with clean energy power generation devices concentrated in one area to save space.

[0039] It should be noted that the wind power generation module 120 and the photovoltaic power generation module 110 need to be installed in open areas, especially the wind power generation module 120, in order to make better use of wind energy.

[0040] Optionally, both the first water tank 210 and the second water tank 220 are equipped with probes, which are electrically connected to the intelligent control device to monitor the first water tank 210 and the second water tank 220. In practical applications, when abnormal water levels, tank deformation, or toxic gases are detected in the water tank, an alarm is issued and the signal is transmitted to the host of the intelligent control system. The host then issues a command to stop energy storage regulation and simultaneously empties the water tank (first water tank 210 or second water tank 220) where the accident occurred.

[0041] Optionally, the vertical distance between the first water tank 210 and the second water tank 220 is 8m-15m. If the vertical distance between the first water tank 210 and the second water tank 220 is too low, the mechanical potential energy of the sewage will be too small, and the power generation of the turbine generator set will be small; if the vertical distance between the first water tank 210 and the second water tank 220 is too high, the power consumption during pumping and storage will be too large.

[0042] For example, the vertical distance between the first water tank 210 and the second water tank 220 can be 8m, 10m, 12m or 15m, etc.

[0043] Optionally, the pump unit includes a pump 231 and a first pipeline group 232, with both ends of the pump 231 connected to the first water tank 210 and the second water tank 220 respectively through the first pipeline group 232; the turbine generator unit includes a turbine 241 and a second pipeline group 242, with both ends of the turbine 241 connected to the first water tank 210 and the second water tank 220 respectively through the second pipeline group 242, so that the sewage in the first water tank 210 and the second water tank 220 can be circulated through the first pipeline group 232 and the second pipeline group 242.

[0044] In this embodiment, both the first pipe group 232 and the second pipe group 242 are made of high-gloss material to reduce fluid resistance and thus reduce energy consumption.

[0045] Continue as Figure 1 As shown, the water pump 231 is installed on the ground for easy installation; the first pipe assembly 232 includes a first straight pipe extending horizontally and a second straight pipe extending vertically. The two ends of the first straight pipe are connected to the second water tank 220 and the water pump 231, respectively, and the two ends of the second straight pipe are connected to the first water tank 210 and the water pump 231, respectively. Compared with bends, the first and second straight pipes can reduce the flow path of sewage and reduce energy consumption.

[0046] Similarly, the turbine 241 is located on the ground, making installation convenient; the second pipe assembly 242 includes a third straight pipe extending horizontally and a fourth straight pipe extending vertically. The two ends of the third straight pipe are connected to the second water tank 220 and the turbine 241, respectively, and the two ends of the fourth straight pipe are connected to the first water tank 210 and the turbine 241, respectively. Compared to bends, the third and fourth straight pipes can reduce the flow path of sewage and reduce energy consumption.

[0047] Optionally, the intelligent control device incorporates an AI algorithm to analyze nonlinear wind changes and intelligently control the wind power generation component 120 to maximize the utilization of wind power.

[0048] It should be noted that the intelligent control device's built-in AI algorithm also has the functions of monitoring, scheduling, and optimizing the photovoltaic power generation module 110 and the pumped storage device. The AI ​​algorithm analyzes and predicts information such as weather conditions such as heavy rain and strong winds, electricity demand, and sewage quality and quantity, and then sets operating strategies for each device and makes timely adjustments according to the on-site conditions to ensure maximum energy utilization.

[0049] Specifically, the AI ​​algorithm of the intelligent control device analyzes historical local wind data to formulate and implement the optimal control strategy for the conventional wind power generation module 120, and makes temporary adjustments based on weather forecasts when facing strong winds. The AI ​​algorithm also analyzes past electricity consumption data to predict current peak and off-peak electricity demand. In this case, the intelligent control device adjusts the wastewater treatment plant's energy storage control system in conjunction with wastewater operation data. For example, when the photovoltaic power generation module 110 and wind power generation module 120 are generating well, and the electricity load of the wastewater treatment plant's electrical facilities is low or predicted to be at a low point, the water pump unit is activated to pump wastewater from the second water tank 220 to the first water tank 210 to store excess electrical energy. The photovoltaic power generation module 110... When the wind power generation component 120 is not generating power, or when the power load of the electrical facilities in the sewage treatment plant is high or when peak power demand is predicted, the turbine generator set is started. At the same time, the sewage in the first water tank 210 is released to drive the turbine generator set to generate electricity to meet the power demand. In special circumstances where there is a large amount of emergency wastewater, the intelligent control device releases the sewage in the first water tank 210 to the second water tank 220 and connects the emergency wastewater pipeline to start storing the emergency wastewater. Based on the multiple probes installed on the first water tank 210 and the second water tank 220, when abnormal water level, tank deformation and toxic gas are detected in the tank, an alarm is issued and the signal is transmitted to the host of the intelligent control system. The host issues an instruction to stop energy storage regulation and at the same time empties the water tank (first water tank 210 or second water tank 220) where the accident occurred.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
