Accurate topological information is crucial in supporting the coordinated operational requirements of source-load-storage in low-voltage distribution *** coverage of smart meters provides a database for low-voltage topology identification(LVTI).However,because of electricity theft,power line commu-nication crosstalk,and interruption of communication,the measurement data may be *** can seriously affect the performance of LVTI ***,this paper defines hidden errors and proposes an LVTI method based on layer-by-layer stepwise *** the first step,a multi-linear regression model is developed for consumer-branch connectivity identification based on the energy conservation *** the second step,a significance factor based on the t-test is proposed to modify the identification results by considering the hidden *** the third step,the regression model and significance threshold parameters are iteratively updated layer by layer to improve the recall rate of the final identification ***,simulations of a test system with 63 users are carried out,and the practical application results show that the proposed method can guarantee over 90%precision under the influence of hidden errors.

In distribution network,with the installed of photovoltaic（PV）,bought many *** of the most concerned problems is the overvoltage in the terminal bus of distribution *** is caused by the reverse power flow which brought out by the increase of the PV sources *** this paper,an improved PQ-Q（V） control strategy is proposed to alleviate such *** economic performance and the efficiency are considered in this prosed *** photovoltaic grid-connected inverter is controlled to compensate the overvoltage or under voltage by compensating the inductive and capacitive reactive power to ensure voltage are within rated *** performance is compared with a traditional control *** this basis,the influence of the method on the network is investigated,which have been found that the value of tune parameter will affect the regulate ability and the system *** this paper,the 13-bus IEEE network is used in the simulation of DIgSILENT software.
