Abstract
The abstract of the work "Power System Reliability Analysis Considering Battery Energy Storage System" gives an outline of the inquire about and its key findings. The paper presents the concept of power system reliability and its significance in guaranteeing the smooth and persistent operation of electrical grids. It highlights the developing significance of battery energy storage systems in improving the reliability of power systems, offering the potential to store abundance
energy and give backup power amid blackouts. The paper points to analyse the effect of joining battery energy storage systems on the overall reliability of power systems, taking into account different operational and specialized perspectives. Nevertheless, there is continuous need for clean and sustainable energy worldwide. This need has facilitated the increasing penetration of Renewable Energy Sources (RES), such as wind, solar, and hydro power. With their ntermittent nature, renewable energy sources often exhibit large fluctuations in power outputs, which presents a great challenge to the existing power grid to maintain its secure and reliable operation. The possibility exists that the excess energy produced by renewable energy sources can be stored and released when the renewable production levels are less than the demand. In this way, renewable energy will become as controllable as other primary sources of energy. In this project, energy storage will play a significant role in grid modernization by providing other functions such as increasing reserve and operating capabilities of the grid, improving system stability and reliability, lowering cost, as well as deferring system upgrades. Though the need and the advantage of energy storage systems have been well recognized, there is still a lack of cost effective ways of storing electric energy. For example, the USA currently has about 24.9 GW
(approximately 2.3% of total electric production capacity) of grid storage although most of this is from hydro pump stations [1]. However, it is almost impossible to exploit electro-hydro resources on a large scale without affecting the local ecological systems. Thus, new electric energy storage technologies are being continuously pursued to not only provide reliable energy storage at low cost, but also provide fast response, scalability, and ubiquitous installation across the power grid. Battery Energy Storage Systems (BESSs) are a solution to manage and control the new loads and renewable energy sources as well as taking part in the stabilization of the grid. Therefore, in general deployment of BESSs on the grid is as important as electricity itself.
