Distributed energy storage refers to small-scale energy storage systems located at the end user site that increase self-consumption of variable renewable energy such as solar and wind energy. These systems can be centrally coordinated to offer different services to the grid, such as operational flexibility and peak shaving.
Energy storage is an enabling technology for various applications such as power peak shaving, renewable energy utilization, enhanced building energy systems, and advanced transportation. Energy storage systems can be categorized according to application.
Firstly, by extracting large-scale user electricity consumption data, insights into users' electricity usage patterns, peak/off-peak consumption characteristics, and seasonal variations are obtained to establish a behavioral indicator system for user-side energy storage.
The user-side energy storage, predominantly represented by electrochemical energy storage, has been widely utilized due to its capacity to facilitate renewable energy integration and participate in capacity markets as a responsive resource [4, 5].
It is observed that energy storage systems with higher power density are often used for short-duration applications requiring fast response such as grid voltage maintenance. Storage systems with higher energy density are often used for long-duration applications such as renewable energy load shifting . Table 3.
A comprehensive lifecycle user-side energy storage configuration model is established, taking into account diverse profit-making strategies, including peak shaving, valley filling arbitrage, DR, and demand management. This model accurately reflects the actual revenue of energy storage systems across different seasons.
