Research on Operation Strategy of the Application of Dual Energy Storage Coupled with Coal-Fired Units in New Energy Power System

  Introduction  With the increasing proportion of new energy power consumption, the development of energy systems with coal-fired units coupled with dual energy storage technology has received wide attention.   Method  Based on a systematic analysis method in terms of energy system composition, energy storage technology characteristics, applications, technical bottlenecks, etc., an operational control strategy study was carried out for coal-fired units coupled with dual energy storage technology under wind power and photovoltaic embedding to participate in power system peaking applications.   Result  It is found that a dual energy storage system coupled with the coal-fired unit can effectively solve the operation stability, efficient energy utilization, and technology economic issues of new energy systems through different structural compositions and optimization of operation strategies. However, this integration system has not reached the stage of large-scale commercial application.   Conclusion  The promotion and application of dual energy storage coupled with the coal-fired unit in new energy systems require continuous work on the strategic optimization of dual energy storage technology and the development of energy storage technology itself.
