Abstract: A source-network-load-storage coordination dispatching method in a background of a coupling of renewable energy sources, including: taking an expectation of a minimum grid operating cost in a dispatching cycle as an objective function; generating an approximate value function of an output of a set for generating electricity from renewable energy sources and a user load, and constructing a source-network-load-storage coordination dispatching model with combination of the objective function; obtaining forecast data of the output of a set for generating electricity from renewable energy sources and the user load, and inputting the forecast data into the dispatching model for solving; performing iterative updating on the approximate value function, importing the approximate value function after the iterative updating into the dispatching model for iterative solving, and terminating an iterative process until a solving result satisfies a preset convergence condition; and using a solving result of a last iteration

Abstract: Disclosed are a photovoltaic energy storage offline coordination system and method based on demand management. The system includes a photovoltaic generator set, an inverter, a dispatch and control device for charge-discharge, a load monitor, a first and second energy storage device, and a remote console. The photovoltaic generator set is electrically connected to the dispatch and control device for charge-discharge via the inverter; the first energy storage device is connected to a load-side power supply bus via a first dispatch and control unit; the second energy storage device is connected to the load-side power supply bus via a third dispatch and control unit; a second dispatch and control unit is connected to the load-side power supply bus; the load monitor is provided at the load-side power supply bus, and configured to monitor a load of the load-side.

Abstract: A flip trash can, including: a trash can body for containing trash, a lid, a locking member, a clamping piece on the locking member, a clamping portion on the lid and a flip-limiting structure. The lid and the locking member are hingedly connected to an opening of the trash can body, and arranged coaxially through the hinged shaft. The clamping piece is matched with the clamping portion. The clamping piece is configured to engage with or disengage from the clamping portion to respectively realize engagement and disengagement between the lid and the locking member. The flip-limiting structure is connected to the locking member to drive the locking member to turn over relative to the trash can body, thereby driving the lid to turn over relative to the trash can body.

Abstract: An electronic device receives a first media content item and receives information indicating: a first insertion time within the first media content item; and a second media content item to be played at the first insertion time and/or one or more properties of the second media content item. The electronic device stores the first media content item. The electronic device provides the first media content item to the second electronic device, including queuing the second electronic device to playback, in sequence and without user intervention: the first media content item until the first insertion time; the second media content item at the first insertion time; and the first media content item resumed after playback of the second media content item is ceased.

Abstract: A fixing structure for lid assembly and disassembly of a trash can, including a hanging structure. The trash can includes a trash can body, a lid and a connecting part. The hanging structure includes a groove and a hanging part. The groove is provided on an outer side wall of the trash can body. The hanging part is provided on the lid. The hanging part and the groove are configured to be engaged with or disengaged from each other to enable the attachment of the lid to the trash can body or the detachment of the lid from the trash can body. When the connecting part is disengaged from the lid, the lid is hung on a side of the trash can body.

Abstract: A trash can having an easy-to-assemble lid and a decorative ring, including a trash can body and a lid in a split-type design. The lid is arranged at an opening of the body, and can flip with respect to the body. The lid is configured to cover the opening of the body. The trash can further includes a connecting part at the opening of the body. The connecting part is in snap-fit connection with the lid, and is capable of flipping with respect to the body to drive the lid to flip with respect to the body.

Abstract: Systems and methods for audio advertising user interaction are disclosed. A voice interactive device causes an advertising audio file to be played for a user. The user can express interest in the advertising content of the advertising audio file by speaking one of a plurality of predetermined intents. Based on expressed user response, one or more results can be provided to the user and/or to a user device. The results relate to advertising content of the advertising audio file.

Abstract: An electronic device associated with a media-providing service receives a first media item, including information indicating: a first insertion time within the first media item and a second media item to be played at the first insertion time. The electronic device stores the first media item, including information indicating the first insertion time and information indicating the second media item. In response to receiving a request from a second electronic device to initiate playback of a first media item the electronic device provides the first media item to the second electronic device, including queuing the second electronic device to playback, in sequence and without pausing and without user intervention: the first media item until the first insertion time, the second media item at the first insertion time, and the first media item beginning at the first insertion time after playback of the second media item is ceased.

Abstract: An inductive cover assembly is configured to connect a can body of a trash can. A side of the can body is provided with an assembly groove extending downward. The inductive cover assembly includes an insert, and an inductive ring and a cover that are hinged to the insert. The assembly groove and the insert are pluggably connected, so as to allow the inductive cover assembly detachably arranged on the can body. Therefore, there is no need to remove the inductive cover assembly during the replacement of trash bags.
