Battery Energy Storage Applications: Two Case Studies

The worldwide increasing energy consumption resulted in a demand for more load on existing electricity grid. The electricity grid is a complex system in which power supply and demand must be equal at any given moment. Constant adjustments to the supply are needed for predictable changes in demand, such as the daily patterns of human activity, as well as unexpected changes from equipment overloads and storms. Energy storage plays an important role in this balancing act and helps to create a more flexible and reliable grid system. In additional, most developed countries have adopted policies to reduce nuclear and fossil fuel consumption and to increase the renewabies energy plant as wind power, hydroelectric, solar thermal, solar thermo-electric and photovoltaic. To reduce the dependence of the renewable energy on the hour duration of the wind and sun it is important to develop and use the various technologies of energy storage. Among these, battery energy storage systems (BESS) are currently escalating and trending major growth in the world market. The paper mainly discuss different applications of BESS and exemplifies with two study cases.
