morning March 8, 2022，Zhang Shidong, a senior work of Zhang Shidong, Institute of Electricity Science, Shandong Electricity Company，Liu Yang senior，Li Shuai engineer visited the new energy DC power distribution system laboratory in our hospital，And introduced by Professor Sun Yuanyuan in the low -voltage DC power system，I have a detailed understanding of the scientific research situation of the new energy DC electricity team。

In the visit and exchange，Subtitator Sun Kaiqi first introduced the team's low -voltage DC installation real scene simulation platform，It is a set of new energy power generation、m88 com live casino registerDouble -end low -voltage DC transfiguration power system composition of energy storage and electricity load，Switching with grounding，Flexible networking functions such as network topology switching，Provide the basics for the research of the low -voltage DC power system。At the same time, the system has DC failure simulation、Data collection and energy management functions; subsequent，Sun Kaiqi introduced to you the multi -port power grid simulation power supply，It can be used for AC power supply power supply、DC power distribution power supply and wind power mechanical electromagnetic dual simulation，and show the full DC load room provided by cooperation with Gree Electric，Including: DC air conditioning、DC rice cooker、DC lighting、DC TV、DC water purifier and other typical DC electricity equipment，Represents DC motors、Ultra -power pure resistance and low -voltage m88 com live casino registersmall power category。Finally introduced the moderate high -voltage DC power distribution simulation platform with a modular multi -level stream replacement prototype，The platform controller is used to simulate multi -end DC distribution network，distributed photovoltaic、DC load, etc.，Parameters in the control system、Change the control strategy，Study the characteristics of the DC network operation under different conditions，For the operational mechanism of studying medium and high voltage DC power distribution，Fault protection and coordination control methods provide physical experimental environment。

After the visit，Under the host of Professor Sun Yuanyuan，Talks about the problems encountered in scientific research and the next step of cooperation。Subsequent researcher Sun Kaiqi proposed to consider relying on the establishment of a unified photovoltaic testing criteria m88 sports bettingfor the establishment of a unified photovoltaic test;，Give suggestions from the user side; then，Data monitoring from both parties、Analysis and processing conducted specific discussions; finally，Professor Ma Zhao, a special professor of Shandong University, approve the project for international standards、Standard、Process and other questions，I made some suggestions for my own，Think that scientific research must have your own specialty，Get the recognition of the industry in the relevant field，The direction of scientific research should be in line with the general direction of national policies，It must be sustainable。

The visit of Zhang Shidong, the Institute of Electrical Sciences, and a group of senior engineers and groups of senior groups，Strengthen the cooperation and exchange of Shandong Academy of Electrical Sciences and the School of Electrical Engineering, m88 sports bettingShandong University in the field of low -voltage DC，further enhances the influence of the research team of new energy medium -low -voltage DC power system，It also promoted the team's academic progress and application practice in the field of low -voltage DC training。
