Research on intelligent pumped storage power station based on digital twins technology

In order to build a new power system and achieve the goal of carbon peak and carbon neutralization, intelligent power grid and large-scale intermittent new energy has developed rapidly, as a consequence, the situation of power grid is increasingly complicated. Pumped storage power station, as a key technology of energy storage, which can effectively coordinate the peak-valley contradiction of power grid, is gradually transforming to the direction of intelligence and digitalization. In this context, the development characteristics and difficulties of intelligent pumped storage power stations are explored. Based on BIM and GIS fusion technology, the hierarchical framework of digital twins of pumped storage power station is proposed, the construction of the digital twins of pumped storage power station is elaborated simultaneously. Two application cases of digital twins in pumped storage power stations are introduced combined with operation and maintenance, which provides technical support for intelligent construction of pumped storage power stations with high engineering practical significance.
