Accelerate the construction of pumped-storage power stations, study and explore the cascade integration of conventional hydropower stations, build hybrid pumped-storage power stations, and actively develop electrochemical energy storage. Guide the large-scale application of power-side energy storage, and actively support the development of user-side energy storage. Promote the transformation and upgrading of coal-fired power units. Comprehensively sort out the operation of coal-fired power units, and propose transformation plans by classification. Actively explore the integrated development and operation mode of coal power, renewable energy and energy storage.

(3) Promote the upgrading of the power transmission and distribution system. Improve the power transmission and distribution system, and accelerate the construction of a smart grid with UHV as the backbone and coordinated development of power grids at all levels. Continue to optimize the main network frame. Strengthen the west-to-east power transmission and the north-south mutual economic transmission channel to realize the full coverage of the 500 kV power grid in cities and prefectures, and the 220 kV power grid in the whole province, districts and counties. Comprehensively improve the operating efficiency and security level of the power system, and enhance the optimal allocation and consumption of clean energy. Transform and upgrade the distribution network. Promote the intelligent, digital and active transformation of the distribution network, and promote the upgrading of the province's distribution network. Improve the reliability and intelligence of the power grid in the central urban area, and continue to consolidate and improve the overall power supply quality and service level of the rural power grid. Promote the digital transformation of the power system. Relying on technologies such as "big wisdom and cloud", a digital information perception and transmission system covering all aspects of the power system is formed. Give full play to the role of the province's energy big data intelligence platform, and improve energy digital management.

(4) Improve the level of power operation and dispatch. Innovate the working mechanism of power operation and dispatch, and continuously improve the overall operation level of the power system. Create an efficient power dispatching system. Improve the work specifications of power dispatching agencies, clarify the boundaries of internal dispatching rights and responsibilities, improve the transparency of dispatching information, and ensure smooth dispatching. Accelerate the application of intelligent technology, improve the level of dispatch intelligence and automation, and explore the development of "integration of wind, light, water, fire, and storage" intelligent joint dispatch. Strengthen the supervision of power dispatching operation. Improve the on-site liaison mechanism for coal power projects.
