Future power grid dispatch and control mode with large-scale clean energy integration in China

The breakthrough and wide application of technologies such as distributed generation, clean energy, smart substation, energy storage, and electric vehicles have a profound impact on the future of power grid dispatch and control modes. This paper introduces the development and influence of the clean energy program in China, describes the current dispatch and control modes, and then analyzes four components of future dispatch and control modes, including system architecture, data model, dispatch and operation, and closed-loop control based on demands and technology development trends. China's future clean energy power grid will have a widely collaborative operational architecture of “decentralized autonomy and centralized coordination,” enabling it to predict the development of power grid dispatch and control in 2020, 2030, and 2050. We conclude with a discussion of the key technical requirements for future power grid dispatch and control.
