Research on New Energy Storage Grid-connected Operation System for Multi-scenarios

This thesis discusses the challenges of power grid operation, especially the pressure on security and stability and power supply/demand balance, in the context of the current high percentage of new energy access and the wide application of power electronic devices. As a key solution, new energy storage technology can effectively improve the flexibility and stability of the power grid and support the wide application of green energy. This paper takes the Jiangsu power grid as an example, analyses the grid development trend in wind- and solar-rich regions, and evaluates the applicability of new energy storage in multiple scenarios. The study includes the scale analysis of energy storage allocation, the optimal scheduling method of multi-scenario and multi-type energy storage, and the market mechanism and economic analysis of energy storage operation. This paper proposes the development of energy storage for different scenarios, aiming to improve the grid regulation capability, promote new energy consumption, and ensure the safe operation of the grid through the application of new energy storage.
