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.

By Sifat Amin and Mehrdad Boloorchi Battery energy storage systems (BESS) are emerging in all areas of electricity sectors including generation services, ancillary services, transmission services, distribution services, and consumers' energy management services.
For instance, a Battery Energy Storage Medium, as illustrated in Fig. 1, consists of batteries and a battery management system (BMS) which monitors and controls the charging and discharging processes of battery cells or modules. Thus, the ESS can be safeguarded and safe operation ensured over its lifetime.
Although batteries (electrochemical ESSs) are proven options for most distribution network applications and have long lifetime and good efficiency, some options (e.g., NaS, Li-ion, NiCd, VRB, and ZnBr) are costly.
During transients, ESSs can play a major role in maintaining frequency stability by adjusting the grid frequency dynamically and hence improving the stability of the system . The regulation of grid frequency is investigated with a new SoC feedback control strategy in, for a system comprising high penetration of wind generation and ESS.
In its report released in April, Batteries and Secure Energy Transitions, the agency charts out a path for massive growth in battery energy storage consistent with the goal of 'Net Zero' by 2050. Batteries provide an essential lynchpin in plans to reduce global carbon dioxide emissions in the Net Zero vision.
Electrochemical batteries can help provide uninterrupted power supply by storing excess energy produced by VREs when the electricity demand is low and releasing it when demand is high Battery energy storage systems can also provide uninterrupted power supply to users during power outages .
An inadequate deployment reduces the reliability of the power grid, meanwhile, oversizing results in significant costs for the power grid operation. Therefore, significant studies are being conducted for the optimal deployment of battery energy storage systems (BESS) in the power grid.
