An Internet of Things (IoT)-based informationized power grid system and a hierarchical energy storage system are put forward to solve energy storage problems in new energy power construction in remote areas. The system applies IoT to construct a distributed new energy grid system to optimize electric energy transmission. The information model is employed to establish a hierarchical energy storage system to combine the advantages of distributed energy storage and centralized energy storage, thereby enhancing the transmission grid security further. An indicator system is established to evaluate the energy storage system, considering the technology, economy, and society, using the Gray Relational Analysis model. Finally, the designed energy storage system is evaluated comprehensively. Experimental results demonstrate that the IoT-based hierarchical energy storage system can alleviate the peak overload of the new energy distributed power generation system. The experiment verifies the effectiveness of the proposed model for new energy storage systems. The comprehensive evaluation result of the lithium battery energy storage system is the highest, with a correlation value of 0.89. Hence, the lithium battery energy storage system has a wider application prospect. The research results can contribute to establishing a distributed new energy storage system based on IoT technology.
