5month13日，China Science News published a forward-looking technical perspective article "Future Power Supply and Consumption System: New Generation of Low-Voltage DC" by Professor Ma Zhao from the School of Electrical Engineering of our school。The Chinese Academy of Sciences is the highest academic institution in the field of science and technology in my country and a national comprehensive research and development center for natural sciences and high technologies。China Science Journal is sponsored byChinese Academy of SciencesSupervisor,Chinese Academy of Sciences、Chinese Academy of Engineering、National Natural Science Foundation of China、China Association for Science and TechnologyCo-sponsored central-level newspapers and periodicals，News media units approved by the State Administration of Press, Publication, Radio, Film and Television,It has extremely high authority and credibility.
At the end of April this year, Professor Ma Zhao proposed "new energy low-voltage DC power supply-a new form of future power supply system" for the National Energy Administration's 14th Five-Year Plan。This forward-looking technology perspective article published in China Science Journal，It is to provide suggestions and suggestions for the 14th Five-Year Plan of National Electric Power and Energy，Also speaks for Shandong University。The article explains the characteristics of the new generation of low-voltage DC power supply system、Mode、Application and significance，With low carbonization、Digital、Intelligent、Sustainable energy system as construction goal，It is recommended to include the “new power supply and consumption model integrating distributed photovoltaics + low-voltage DC power supply + energy storage” into the 14th Five-Year Plan energy plan。The article recommends carrying out top-level design，Planning first，Standard support。Comprehensive differentiation、Customized、Requirements for flexibility and flexibility，With the goal of improving social and economic benefits，Integrated photovoltaic building integration、Low carbon green building、5G communication power supply、Rural re-electrification、Smart home and other fields，Planning new directions，Make a new route；Recommended to encourage social capital investment，Promote new energy low-voltage DC power supply systems in the form of photovoltaic building DC integration and other forms on a pilot basis in rural and urban communities，Establish a mechanism to guide and promote；At the same time, it is proposed to shift from physical thinking to biological thinking、From “Network Thinking” to “System Thinking”、Three transformations from a purely technical concept to a socio-economic perspective；A way of thinking that combines "hardware combination" from a technical perspective and "software combination" related to economic society and humanities；In pursuit of adaptation、Contact、Symbiosis，Solve complex、Cross-border、Systemic problem；It is recommended to encourage and support innovative demonstration applications，Encourage and support local governments and related enterprises to develop unit designs that are demonstrative and can be truly replicated、Engineering，Gradually promote new development through pilot demonstrations，And hope that the new energy low-voltage DC system can contribute to the new infrastructure，Becoming a new power supply and consumption method and business model that subverts traditional AC power supply。
In recent years，Professor Ma Zhao is committed to developing scientific research work in the field of low-voltage DC power supply，Give keynote or invited lectures in many academic activities at home and abroad，Leading the development of this field，Also represents China’s voice on the international stage。Shandong University’s “New Energy DC Power Distribution System” research team led by Professor Ma Zhao，Featuring “Internet of Things + DC Power”，Under construction for scientific research、Comprehensive DC transmission-distribution-supply-use laboratory for technical verification and functional demonstration，Key technologies in DC power distribution、Flexible DC coordinated operation、Carry out scientific exploration and technical research in the fields of power quality analysis and other fields，Aims to promote and lead the development of domestic low-voltage DC power supply technology and the construction of new digital infrastructure。
