Energy storage systems that lead to the deferral of T&D upgrades allow for a more efficient deployment of capital to meet evolving grid needs and can enable the development of new business models.
Energy storage systems that are properly placed on the transmission system can be used to relieve transmission congestion . Similarly, storage on distribution can be used to reduce peak loads . The reduction in currents produced by congestion relief and peak reduction may also result in a decrease in line losses.
Improves grid efficiency: Energy storage is instantly dispatchable to function both as generation and load, so it can help the grid adjust to fluctuations in demand and supply, which optimizes grid efficiency, alleviates transmission congestion, and increases grid

infrastructure needed to move power from generation sources to end users. Although most power flowing on the transmission and distribution grid originates at large power generators, power is sometimes also supplied back to the grid by end users via Distributed Energy Resources (DER)— small, modular, energy generation and storage technologies
The optimized configuration of energy storage is an effective way to deal with the fluctuation of renewable energy output and insufficient system flexibility , which has been a hot topic for research.Energy storage plays a critical role in the power system, such as wind power fluctuation suppression , frequency response [9, 10], spinning reserve , peak shaving [12, 13] as well

The global imperative to address environmental pollution has propelled authorities in industrialized and developed nations to institute measures aimed at curbing emissions from fossil fuels, particularly those used in energy production (Elkadeem et al., 2019) nsequently, there has been a noticeable surge in the integration of renewable energy sources (RES) into
Power grid congestion is a situation wherein the existing transmission and/or distribution lines are unable to accommodate all required load during periods of high demand or during emergency load conditions, such as when an adjacent line is taken out of service or damaged by a storm, commonly referred to as an “N minus 1” or “N minus 2” condition—or worse.
5.2.1. Basic data and calculation assumptions From Case 1, it can be seen that energy storage is helpful for alleviating transmission congestion. And in Case 2, an economic analysis is conducted on a practical 129-bus system, which can check the feasibility and economy of the proposed method.
Anticipating and relieving congestions is an ongoing challenge for transmission system operators. Distributed grid-scale battery energy storage systems enable operators to shift power flows and remedy congestion through virtual power lines and grid boosters.
Numerical experiments are carried out on a modified IEEE-RTS 24-bus system and a practical 129-bus system. Numerical results show that energy storage can improve the flexibility of power system operation and the utilization of renewable energy generation.
Furthermore, it outlines curative ad-hoc measures to overcome uncertainties during operational planning and real-time operation. The simulation results indicate that battery energy storage systems further increase the use of curative measures and reduce congestion management costs.
Therefore, energy storage can store the energy during the peak periods of the renewable energy outputs and release it during the uncongested periods, which can also reduce the investment for power transmission and distribution equipment.

If the key components causing the transmission congestion are evaluated and identified, then energy storage can be reasonably configured. It absorbs energy when the components are congested and releases energy during the uncongested periods.
