Demonstration Study on the Large-Scale Battery Energy Storage for Renewables Integration

Abstract

The penetration level of the renewable energy resources has been expected to increase rapidly in several years as government has strongly encouraged those through various policies such as the RPS (Renewable Portfolio Standards) and feed-in tariffs. Because the performance of power system is sometimes critically constrained by stability characteristics, it is very challenging for system operator to realize such a high penetration of the renewable energy resources in power system. It has been proposed that the large-scale Energy Storage Systems (ESS) can be applied to the power system for stabilizing the power supply and improving the energy efficiency ratio by using the stored electrical power in the period of high demand for electricity. To implement the large capacity and improve the effectiveness of the lithium-ion battery ESS, it has been constructed 4MW/8MWh ESS test-bed and developed the operation technology of ESS. In this paper, a demonstration study scheme on the large-scale Battery Energy Storage System (BESS) is proposed to verify the effectiveness and to estimate the performance of BESS.

A Review on Applications of Layered Phosphorus in Energy Storage

“…In order to solve the volume expansion, researchers proposed the following solutions. (1) Reducing the diffusion distance of the high ion diffusion energy barrier, reducing the black phosphorus, especially the grain size along the armchair, can improve rate performance. (2) Introduction of heteroatom doping and vacancies can, respectively, reduce their diffusion energy barrier or provide a new diffusion channel for lithium ions, and adjust the adsorption binding energy of lithium.…”

“…Very recently, N-doped blue phosphorus was also demonstrated to be a promising catalytic material in the cathode of LABs by DFT calculations based on the following characteristics [132]. (1) The blue phosphorus monolayer was stable during adsorption in the lithium-ion processes, contributing to sustaining a long-term electrochemical stability. (2) The low barrier energy of 0.11 eV along path 4 in Fig.…”

“…With the deterioration of the natural environment and exhaustion of resources, the development, and utilization of clean energy has received much attention. Researchers are committed to developing sustainable energy based on wind and solar power; however, these sources are dependent on natural conditions [1,2]. Compared with wind and solar power, electric energy, such as rechargeable batteries, is efficient, safe, and affordable.…”

Assessment of Battery Storage Technologies for a Turkish Power Network

“…The idea of using battery systems in power grids first emerged in the 1980s. Notable examples since the 1980s are the BESS in Berlin, Lausanne, South Korea, Jeju Island, and other small island systems [133][134][135][136][137][138]. The integration of BESS in the power grid helps to solve many problems of the power grid [139][140][141][142][143].…”

On-grid batteries for large-scale energy storage: Challenges and opportunities for policy and technology

“…The idea of using battery energy storage systems (BESS) to cover primary control reserve in electricity grids first emerged in the 1980s. 25 Notable examples since have included BESS units in Berlin, 26 Lausanne, 27 Jeju Island in South Korea, 28 and other small island systems. 29,30 One review of realized or planned BESSs for ancillary service provision showed an average capacity of more than 4 MW h per BESS.…”
