Distributed predictive control based voltage restoration scheme for microgrids

A distributed predictive control based voltage restoration scheme for microgrids, comprising: step 10) adopting a distributed finite time observer to acquire the global reference voltage for restoring the voltage of each local controller; step 20) each local controller adopts a droop control to acquire the local voltage value of each generation, and adds a secondary voltage compensation term into the droop characteristic formula to form the voltage reference value of a distributed generation; step 30) establishing a trended prediction model; step 40) acquiring a predictive control term at a current time as the secondary voltage compensation command, and acting on the local controllers; and step 50) determining, whether the local voltage of each distributed generation of the microgrid reaches the voltage reference value under the secondary voltage compensation command.. . ...

Wafer-level manufacturing method for embedding passive element in glass substrate

A wafer-level manufacturing method for embedding a passive element in a glass substrate is disclosed. A highly doped silicon wafer is dry etched to form a highly doped silicon mould wafer, containing highly doped silicon passive component structures mould seated in cavity arrays; a glass wafer is anodically bonded to the highly doped silicon mould wafer in vacuum pressure to seal the cavity arrays; the bonded wafers are heated so that the glass melts and fills gaps in the cavity arrays, annealing and cooling are performed, and a reflowed wafer is formed; the upper glass substrate of the reflowed wafer is grinded and polished to expose the highly doped silicon passives; the passive component structure mould embedded in the glass substrate is fully etched; the blind holes formed in the glass substrates after the passive component structure mould has been etched is filled with copper by electroplating; the highly doped silicon substrate and unetched silicon between the cavity arrays are etched, and several glass substrates embedded with a passive element are obtained; to form electrodes for the passives, a metal adhesion layer is deposited, and a metal conductive layer is electroplated. ... Southeast University

Joint non-coherent integral vector tracking method based on spatial domain

The present invention discloses a joint non-coherent integral vector tracking method based on a spatial domain, which is used for further improving the performance of a vector tracking gps (global positioning system) receiver. In a new vector tracking strategy design, a phase discriminator/a frequency discriminator in a traditional vector tracking loop is discarded, and baseband signals of visible satellites in each channel are taken as an observation value after performing non-coherent integration, and eke (abbreviation of extended kalman filter) is used to estimate directly and to solve the position, the velocity, a clock error, etc. ... Southeast University

Pilot allocation method based on coherence time for large-scale mimo system

Disclosed is a pilot allocation method based on coherence time for a large-scale multiple input multiple-output (mimo) system. The present invention achieves optimal allocation of pilot resources by fully utilizing the feature that different users possibly have different moving speeds and coherence time of corresponding channels is accordingly different, thereby improving overall data transmission performance of the system and achieving certain practicability. ...

Method for preparation of lipid bubbles

A preparation method of lipid bubbles by utilizing the principle of natural adsorption and assembly of amphiphilic lipid molecules on a gas-liquid interface comprises the steps of mixing gas-dissolved water containing free bubbles with lipid materials, and then the lipid materials are dispersed in the free gas nanobubble aqueous solution, and, in the presence of free bubbles, adsorbed and assembled on the gas-liquid interfaces so as to form lipid bubbles. The method is different from the traditional ultrasound cavitation, the mechanical force action, the novel ink jet printing method, the microchannel method and other methods for preparing bubbles.. ...
