"The gigawatt shared energy storage technology will drive the optimization of the energy structure and the comprehensive economic development of the whole Qinghai, drive the rapid development of the lithium battery industry and equipment manufacturing industry in Qinghai, and solve the problem of energy storage participating in the power spot market and auxiliary service market." On August 15, Li Yongbin, director of the regulation and control center of State Grid Qinghai Electric Power Company (hereinafter referred to as State Grid Qinghai electric power), said this when talking about the project of "research and development and application of key technologies of gigawatt level shared energy storage blockchain and DC boost device based on UHVDC transmission". By the end of July 2022, the project has been fully started and entered the stage of on-site subject supervision by experts. With scientific and technological innovation and scientific research as the fundamental driving force, relying on the characteristic scene of Qinghai power grid, State Grid Qinghai power strengthens the technical layout, comprehensively carries out theoretical research and technological research and development, promotes the application of new technologies and new equipment and the construction of scientific and technological demonstration projects, leads the energy transformation and development with high-quality scientific and technological innovation, and fully supports the construction of Qinghai new power system demonstration zone. Focusing on the new problems and challenges in new energy control and power security, State Grid Qinghai Electric Power Co., Ltd. has made great efforts to strengthen technological research, make concerted efforts in multi disciplines and multi disciplines, and vigorously support the construction of new power system with scientific and technological innovation to promote the construction of a national clean energy industry highland. "Starting from the promotion of multiple interactions of 'source network load storage', we are trying to solve the technical problems of the new power system of Qinghai Power Grid in four main directions: coordinated operation and control of new energy generation, safe and stable operation of power system, flexible regulation and interaction of load terminals, energy storage technology and market mechanism." Yang Linlin, director of State Grid Qinghai Electric Power Science and Technology Department, introduced. The State Grid Qinghai Electric Power Co., Ltd. is a "test field" for the new power system of the State Grid Corporation of China. In combination with Qinghai's "14th five year plan" development plan and the major demand for the construction of the new power system, the State Grid Qinghai Electric Power Co., Ltd. has initially formulated a special plan for tackling key scientific and technological problems of new power, anchored 21 scientific and technological research tasks, and made overall planning for the whole chain management and control of scientific and technological research, providing a strong scientific and technological guarantee for the construction of the new power system demonstration area in Qinghai. New energy power generation active support technology, new power system simulation technology, electrochemical energy storage power station safe operation technology... One key problem solving plan is fully launched, one road map is being formed, and the effect of science and technology on new power systems is increasingly prominent. After the demonstration project became the first batch of provincial demonstration areas of new power system in Qinghai Province, the State Grid Qinghai electric power has determined the goal of leading and driving the system construction with demonstration projects. The key demonstration project of Qinghai's new power system - "scenery hydrogen storage" comprehensive energy utilization demonstration base is located in yunjiakou, Xining city. "In the future, the base will build six typical scenarios, including hydrogen electricity coupling demonstration platform, compressed air energy storage demonstration platform, wind light water multi energy storage comprehensive control demonstration platform, to provide demonstration samples for many technical studies." Introduced by Yang Libin, deputy manager of new energy testing technology service center of State Grid Qinghai Economic Research Institute. At the same time, the comprehensive energy utilization demonstration base of "solar energy hydrogen storage" will also focus on building a "six in one" multi energy complementary demonstration platform for basic research, R & D demonstration, standard guidance, achievement transformation, promotion and application, and technical training, and promote the application of research results in the actual field
