Abstract:

Due to increase population and the continuous efforts through the global residents to lessen the impact of environment change have caused the prompt usage of renewable based energy plants such as wind power plant and solar centered different power generation units. The usage of such power generating unit is purely dependent upon nature. Additionally, integration of renewable unit to power system causes instability. The frequency stability is one of the important aspects and depends on balance between generation and demand. To restore the frequency deviation back to its normal condition, an effective control strategy called Load Frequency Control (LFC) is adopted. To improve the performance of the control scheme different energy storage technologies can be considered. The storage technology not only has distinctive features of fast response and high energy density but also helps in load leveling, peak shaving, black start support etc. In this paper, comprehensive survey of diverse energy storage technology, its current market scenario and utilization in LFC services are presented by collecting, reviewing and interrupting numerous research articles. From the litertures survey, it is observed that, the existing strategies can be categorized in to two categories that is Grid scale System and Load Scale system. Further, load scale system is sub-categorized into coordinated aggregate system and non-coordinated individual system. In this paper, each control scheme is discussed theatrically also the pros and cons of each is addressed from technical point of view.<
