Abstract

As the development of new power systems accelerates and the impacts of high renewable energy integration and extreme weather intensify, grid-alternative energy storage is garnering increasing attention for its grid-interaction benefits and clear business models. Consequently, assessing the value of grid-alternative energy storage in the system transition has become critically important. Considering the performance characteristics of storage, we propose a value assessment frame-work for grid-alternative energy storage, quantifying its non-wires-alternative effects from both cost and benefit perspectives. Building on this, we developed a collaborative planning model for energy storage and transmission grids, aimed at maximizing the economic benefits of storage systems while balancing investment and operational costs. The model considers regional grid interconnections and their interactions with system operation. By participating in system operations, grid-alternative energy storage not only maximizes its own economic benefits but also generates social welfare transfer effects. Furthermore, based on multi-regional interconnected planning, grid-alternative energy storage can reduce system costs by approximately 35%, with the most significant changes observed in generation costs. Multi-regional coordinated planning significantly enhances the sys-tem’s flexibility in regulation. However, when the load factor of interconnection lines between regions remains constant, system operational flexibility tends to decrease, leading to a roughly 28.9% increase in storage investment. Additionally, under regional coordinated planning, the greater the disparity in wind power integration across interconnected regions, the more noticeable the reduction in system costs.
