4results about How to "Improve load characteristics" patented technology

The invention belongs to the technical field of power distribution system planning, and particularly relates to a grid-based source network load storage layering and partitioning balance model. Comprising the following steps: S1, dividing a power distribution system into three levels, namely a power utilization grid, a power supply unit and a power supply grid; s2, determining partition boundary internet access interface parameters of the power utilization grid and a related power flow constraint equation; s3, determining partition boundary internet access interface parameters of the power supply unit and a related power flow constraint equation; s4, determining partition boundary internet access interface parameters of the power supply grid and a related power flow constraint equation; the method can effectively control the maximum load level needing power supply of the power transmission system, distinguishes the difference of the conventional load and the controllable load on the power supply reliability requirements, adopts an effective control means, reduces the maximum load demand of the system, improves the load characteristics of the system, and plays an important role in improving the utilization rate of power grid asset equipment and the asset investment benefit. And planning and realization of integration of the source, the network, the load and the storage in the power distribution system can be effectively promoted.

A secondary battery includes a positive electrode for a secondary battery, a negative electrode, and an electrolytic solution. The positive electrode for a secondary battery includes a positive electrode active material for a secondary battery. The positive electrode active material for a secondary battery includes first particles and second particles. The first particles have a median diameter D50 of greater than or equal to 15 micrometers and less than or equal to 30 micrometers and each include a lithium-containing compound. The second particles have a median diameter D50 of greater than or equal to 1 micrometer and less than or equal to 10 micrometers and each include a center part that includes a lithium-containing compound and a covering part provided on a surface of the center part. The covering part includes, in order from a side closer to the center part, an underlayer and a surface layer. The underlayer includes a reaction product of a first metal alkoxide in which no alkyl group is bonded to a metal atom. The surface layer includes a reaction product of a second metal alkoxide in which the alkyl group is bonded to the metal atom. The reaction product of the second metal alkoxide is bonded to the reaction product of the first metal alkoxide.

The invention relates to a micromechanical component for a sensor device, having a first seismic mass (30a), wherein the first seismic mass, which is displaceable from its first rest position in a first direction (44) over a first limit path along a first axis, mechanically contacts a first stop structure, and having a second seismic mass (30b), which is displaceable from its second rest position at least along a second axis, wherein the second axis is parallel to or lies on the first axis, wherein a second stop surface (50b) of the second seismic mass, which is displaceable from its second rest position in a second direction (46) which is oriented opposite to the first direction along the second axis, mechanically contacts a first stop surface (50a) of the first seismic mass which is attached to the first stop structure. The invention also relates to a method for producing a micromechanical component for a sensor device.
