- Grid-connected performance evaluation of electrochemical energy storage power stations This document specifies the overall requirements for grid-connected performance evaluation of electrochemical energy storage power stations (hereinafter referred to as "energy storage power stations"), the technical requirements for evaluation items and contents, and evaluation methods, and describes the performance of grid-connected equipment of energy storage power stations, the functions of energy storage power stations, and the evaluation methods for grid-connected performance of energy storage power stations.
- Introduction
In-depth interpretation of the grid-connected performance evaluation method of electrochemical energy storage power stations
1. Background and significance of standard formulation
With the large-scale access of renewable energy, the stability and reliability of the power grid are facing new challenges. As a key means to regulate the balance of power supply and demand, electrochemical energy storage technology plays an increasingly important role in the power grid. However, the standardized evaluation of its grid-connected performance is a bottleneck for the development of the industry.
2. Comparative analysis of standard frameworks
Standard dimensions GB/T 42717—2023 Differences in international standards Scope of application Technical requirements Evaluation indicators for grid-connected equipment, functional performance and grid-connected operation are clarified. Aligned with IEEE standards, but more suitable for China's power grid environment. Energy storage power stations with voltage levels of 10kV and above. Evaluation method Emphasis on the combination of data review, on-site verification and experimental testing. More emphasis on the application of actual operating data than international standards. Applicable to the management of power grid dispatching agencies. Improvement measures Propose specific improvement suggestions for unqualified projects. Consistent with the internationally used feedback mechanism, but more detailed. Help improve the overall performance of energy storage power stations.
3. Recommendations for the implementation of the standard
3.1 Establish a standardized evaluation process
According to the requirements of the standard, a detailed evaluation process and operating guidelines should be formulated to ensure the standardization of each link. It is recommended that a professional team be responsible and a regular evaluation mechanism be established.
3.2 Improve data collection and analysis capabilities
Strengthen the online monitoring and analysis capabilities of the operating data of the energy storage power station to ensure that problems can be discovered and measures can be taken in a timely manner. Advanced big data technology can be used for predictive maintenance.
3.3 Strengthen training and technical support
Conduct systematic training for relevant personnel to improve their understanding and application of the standard. At the same time, it is recommended to introduce a third-party technical service agency to provide professional support.
