Academic Lectures:
Sun Xiaofeng: Research on Key Technologies of New Energy Power Routing
The main opinion of experts: In the new energy pooling system, renewable energy units will not only introduce random power disturbances, but also make the system fall into the dilemma of lack of frequency, damping and voltage support. In the future, the penetration rate of renewable energy in the power grid will be further increased, and the safe operation of the power grid will face new challenges after the centralized access of large-scale wind farms and photovoltaic power stations. It is necessary to reserve the efficient and stable collection and grid connection technology of renewable energy to meet the needs of safe operation of the power grid in the future, which is a necessary measure to avoid the bottleneck of renewable energy development again.
Yun Zhang: High-performance Power Conversion and Control Technology for Photovoltaic Storage Microgrid
Experts' main views: Photovoltaic storage microgrid is a distributed power system based on renewable energy, which is mainly composed of photovoltaic power generation system, energy storage system and microgrid management system. The study of the wide-gain DC conversion topology of photovoltaic storage and the control method of high-efficiency operation of photovoltaic storage can improve the efficient utilization level of renewable energy. The identification of inductance and capacitance parameters of grid-connected converters and the improvement of power quality on both sides of grid-connected converters can improve the stability and reliability of photovoltaic storage power systems, and promote the application and promotion of photovoltaic storage systems.
Tian Yanjun: Stability Control Technology of New Energy Power Generation System by Flexible and Direct Grid Connection System
Key Experts' Views: With the massive rise of DC installations such as photovoltaics, energy storage, and electric vehicles, AC/DC hybrid distribution networks are regarded as the most promising networking mode for the next generation, and have received widespread attention in both academia and industry. Therefore, the power routing of power electronic transformers is the core hub of the AC/DC hybrid distribution network in the future, and the research and development of SST technology with multiple power ports and multiple voltage levels is of great significance to promote the development of AC/DC hybrid distribution network.
Chen Kailong: "Clean and Low-carbon, Smart Empowerment, Comprehensive Energy Solutions for Parks"
The main views of experts: In order to solve the pain points such as seasonal power rationing, high electricity costs, and important load supply guarantee in enterprise parks, Guodian Nanzi proposed a set of "clean and low-carbon, intelligent empowerment, and comprehensive energy solutions for the park". The solution covers the energy layer, information layer and value layer, and uses advanced technologies such as non-stop power switching, safe and efficient integration of distributed energy storage, and comprehensive energy optimization operation of the park independently developed by Guodian Nanzi to help enterprises build low-carbon parks and zero-carbon parks. The promotion of comprehensive energy in the park can help realize the efficient and sustainable use of energy and promote the development of green, low-carbon and circular energy applications.
