This application relates to a dynamic topology adaptive power flow optimization system for high-proportion renewable energy access. The system includes a data acquisition unit, a dynamic topology analysis unit, a renewable energy prediction unit, an adaptive optimization unit, and a control execution unit. This system automatically updates the topology and identifies vulnerable areas by tracking real-time changes in grid switch states. It incorporates short-term renewable energy output forecast data into the optimization model and directly links it to the control execution unit to adjust inverter parameters, thus resolving power flow imbalances caused by renewable energy fluctuations. A new safety verification unit simulates strategy execution results, automatically triggering re-optimization upon failure, avoiding delays caused by manual intervention. This system does not rely on complex algorithm models; it achieves fully automated management and control through logical linkage between units. Simultaneously, a human-machine interaction unit allows operation and management personnel to intervene in strategy adjustments, balancing automation and flexibility.

The utility model belongs to the technical field of ultrafiltration energy-saving devices, and particularly relates to an ultrafiltration energy-saving device broken belt detection device which comprises a base, a sleeve is fixedly connected to the interior of the base, a sliding rod is slidably connected to the interior of the sleeve, a mounting plate is fixedly connected to the upper end of the sliding rod, a limiting ring is fixedly connected to the interior of the sleeve, and the limiting ring is fixedly connected to the interior of the base. The limiting ring is slidably connected with the sliding rod, a spring is arranged in the sleeve, the lower end of the base makes contact with an alarm, and a button is arranged at the upper end of the alarm. According to the utility model, the alarm function is realized by additionally arranging the alarm. Meanwhile, the guide wheel, the spring and other components are arranged, when the belt is broken, the spring can drive the guide wheel to trigger an alarm button, and the alarm rapidly gives an alarm. Therefore, the breakage condition of the belt can be perceived at the first time, and the problem that normal operation of the ultrafiltration energy-saving device is affected due to the fact that the driving belt is prone to breakage is effectively solved.

The invention relates to a cover assembly for an earphone, of the type enclosed at the rear of an earphone frame (20), in which a transducer (21) or a sound reproduction medium is arranged. The invention relates to a cover assembly comprising a body (1) delimiting a free first end (6) and a second end (7) housing a transducer (21), characterized in that it comprises: a spacer (8) as a seal made of a fabric or a non-woven, allowing sound to pass through and separating the second cover (4) from the first cover (2) by sealing the second cover (4), an internal friction washer (11) arranged between the spacer (8) and the first cover (2), and an external friction washer (12) arranged between the internal friction washer (11) and the second cover (2). The gasket (11) is arranged on the first cover (2) in the direction of the first end (6), the spiral spring (10) is sleeved on the gasket (11), the fixing device (9) penetrates through the first cover (2), the second cover (4), the spacer (8), the gasket (11) and the spring (10), the first cover (2) or the second cover (4) or the first cover (2) and the second cover (4) are rotated relative to the fixing device (9), and when the first through hole (3) and the second through hole (5) are opposite, the first through hole (3) and the second through hole (5) are in an open position. When the first through hole (3) and the second through hole (5) are staggered, the first through hole (3) and the second through hole (5) are closed.

The application provides a virtual power plant control method, a virtual power plant control device and a smart grid. The method comprises the following steps: obtaining target power data and a communication state of a communication line, and determining a first influence probability of the influence of the communication state on the target power data according to the communication state of the communication line and the target power data; determining whether the first influence probability is greater than a first probability threshold; in the case where the first influence probability is greater than the first probability threshold, determining that an interval of the target power data corresponding to the first influence probability is a target power interval; and controlling the virtual power plant to regulate a power system according to the target power interval. The method solves the problem that the power interval prediction of the virtual power plant in the prior art is inaccurate, which affects the operation of the virtual power plant.
