Abstract

Abstract:

With the proposal of the "dual carbon" target, large-scale clean energy, power electronic equipment and new-type loads are connected to the power system. The traditional power system management and control mode can hardly cope with bilateral randomness and enhanced volatility,which seriously challenges the safe and stable operation of the power system. As an important digitalization means, digital twin has become a new method for power system transformation and upgrading. In response to the profound and complex changes in the internal mechanism of new-type power systems, the development process and research status of digital twin technology applied in power systems are summarized. The digital transformation of power systems is analyzed from three aspects: requirements for new power systems' digitalization, digital modeling methods, and digital platform construction. Finally, a new power system modeling method and framework based on digital twin technology are proposed.

Key words: new power system, digital twin technology, clean energy, digital transformation, power electronic equipment, "dual carbon" target
