Energy Storage System Integration Solutions and Design

This document provides a comprehensive overview of energy storage system integration solutions and design, covering engineering and EPC contracting, core design elements, and investment return analysis. It highlights the background of China's ambitious energy storage targets, with a national goal of 30GW by 2025 and full market-oriented development by 2030, driven by policies from NDRC and NEA. The document discusses the critical role of battery energy storage in enhancing power system flexibility, especially with the increasing share of renewable energy. It details thermal-storage combined frequency regulation, where energy storage's rapid response compensates for slower coal-fired units, improving AGC performance. Flexible regulation resources, including electrochemical storage, are emphasized as key to building a new type of power system, addressing supply-demand imbalances. The summary also outlines potential EPC project owners, such as power companies, solar and wind enterprises, distributed energy operators, EV charging infrastructure operators, energy internet firms, and government parks, all benefiting from energy storage for grid stability, cost reduction, and renewable integration.
