About Zhongke Zhihuan

Zhongke Zhihuan (Beijing) Technology Co., Ltd., also known as zhmicrogrid, is a national high-tech enterprise established in 2018. The company specializes in developing and promoting advanced DC microgrid products, technologies, and system solutions. It has developed a comprehensive suite of solutions for medium-voltage DC microgrids, covering core DC equipment, intelligent energy management systems, and overall system design for source, grid, load, and storage elements. The firm's core technical expertise includes flexible DC transmission, flexible DC protection, and intelligent control. Its product line features independently developed components such as DC energy routers, solid-state power electronic protection switches, and flexible networking channels, which are protected by 25 core patents and 20 core software registrations. These products are designed for a wide voltage range from 1.5kV to 100kV. The company utilizes artificial intelligence, digital twin technology, and big data to develop its coordinated control energy management systems, aiming to enhance the efficiency of renewable energy use. Zhongke Zhihuan targets several key sectors, including green hydrogen production, direct green power supply for non-ferrous metals, DC power for data centers, and low-carbon industrial parks. The business model focuses on providing efficient, low-cost, and replicable DC microgrid system solutions to its clients. For instance, in March 2024, the company was involved in a project for the Inner Mongolia Datang Hualu Aluminum Co., Ltd. to facilitate its green energy transition using a distributed photovoltaic DC access system. To support its operations and growth, the company holds long-term agreement bidding meetings for DC microgrid components, with a tender for 120MW of materials taking place in April 2024. The company's research and development team members have an average of over fifteen years of experience in the new energy and power electronics industries. Zhongke Zhihuan also actively collaborates with academic institutions to foster research and development, maintaining long-term partnerships with Tsinghua University, Harbin Institute of Technology, the State Power Investment Corporation Central Research Institute, and Beijing Institute of Petrochemical Technology.
