On April 28, 2026, the Energy Storage Branch of China Battery Industry Association officially released three group standards: Technical Specifications for Virtual Power Plant Operation, Technical Guidelines for Planning and Configuration of Distribution Transformer District-Side Energy Storage, and Technical Specifications for Grid-Forming Electrochemical Energy Storage Systems Connected to Distribution Networks. As a leading new energy storage R&D and manufacturing enterprise in western China, Chengdu Hope Newenergy Technology Co., Ltd., a subsidiary of Continental Hope Group, was invited to participate in the entire standard development process with its profound technological accumulation and industry influence.

01 Technical Specifications for Virtual Power Plant Operation

This standard specifies technologies for all links of virtual power plants, including technical architecture, access and grid-connection management, terminal equipment, platform construction, dispatching and operation, market trading, performance testing, response evaluation, safety specifications, and risk management. It is applicable to the operation and management of virtual power plants, providing overall scientific guidance for the construction, operation and high-quality development of virtual power plants.

02 Technical Guidelines for Planning and Configuration of Distribution Transformer District-Side Energy Storage

This guideline specifies the technical principles related to site selection, capacity determination, battery selection, and techno-economic evaluation of distribution transformer district-side energy storage. It is applicable to the site selection, capacity determination, planning and design of distribution transformer district-side energy storage in distribution networks of 35 kV and below.

03 Technical Specifications for Grid-Forming Electrochemical Energy Storage Systems Connected to Distribution Networks

This standard specifies the technical requirements and performance evaluation methods for grid-forming electrochemical energy storage systems connected to distribution networks, covering grid adaptability, fault ride-through, inertial response, damping control, primary frequency regulation, overload capacity, grid-islanding switching, black start, mode switching, power quality, relay protection, information and communication, and power quality monitoring. It is applicable to the construction, grid connection, commissioning, testing, inspection and operation of new, reconstructed and expanded grid-forming electrochemical energy storage systems connected to distribution networks of 35 kV and below. Other types of distribution network-side grid-forming electrochemical energy storage systems shall be implemented with reference to this standard.

At present, the energy storage industry is experiencing a period of rapid development, and industry demand is continuously shifting from "project completion" to "efficiency improvement". However, problems such as insufficient relevant standards, safety risks and non-standard operation and maintenance have become increasingly prominent. The introduction of these three group standards has set clear guidelines and norms for the development of the energy storage industry, effectively addressing the shortage of standards in this field, and leading the industry to advance steadily toward safety, standardization and high quality.

During the standard development, the technical team of Hope New Energy fully participated in the whole process of research, demonstration and clause discussion. Relying on years of practical experience in energy storage project construction, operation and maintenance, as well as extensive professional data accumulation, the team put forward a number of professional and constructive suggestions focusing on core links such as project design and implementation, testing and inspection, grid connection, and operation and maintenance control, transforming enterprise experience into industry consensus.

Standards lead the industry, and technology defines discourse power. Chengdu Hope New Energy has always adhered to the development philosophy of "Excellence Beyond Border". Supported by the group's strategic layout, the company has focused on the core track of new energy storage. Guided by the trinity development strategy, it has been deeply engaged in technological R&D, strictly controlled product quality, and continuously optimized performance indicators. It has deeply integrated upstream and downstream resources in the industrial chain, driven development through innovation, and consolidated foundation with quality. Against the backdrop of the "Dual Carbon" strategy, Hope New Energy will continue to fulfill its corporate mission and responsibilities, persist in technological innovation and active participation in standard formulation, continuously empower the upgrading of the green energy industry, fully support the implementation of China's "Dual Carbon" strategy, and consistently contribute to the standardized, high-quality and sustainable development of China's energy storage industry!(Contributed by: Hope New Energy)
