Modeling the Impact of Modified Inertia Coefficient (H) due to ESS in Power System Frequency Response Analysis

Abstract: The advantages of increased penetration of distributed generation are also accompanied by several challenges, low inertia being one of them, which threatens the grid stability. An emerging approach to confront this problem is the introduction of so-called virtual inertia (VI) provided by energy storage systems (ESS). In contrast to the already available literature which considers a conventional load frequency control (LFC) model, this work concentrates on a modified LFC model as the integration of a large port… Show more

“…Some papers, such as [24][25][26][27], deal with these issues, but the load frequency characteristics are often missing. Most actual results are used in modern grid studies such as [28][29][30][31][32][33]. It is of the utmost importance to carry on contingency analyses, static and dynamic stability, and other frequency control studies [34][35][36][37][38].…”

“…where R and X refer to the transmission line resistance (in p.u) and reactance (in p.u), respectively. Thus, Q-V curve can be achieved by solving Equations ( 6) and (7). However, near the lowest point (i.e., the voltage collapse point) of the Q-V curve, the Jacobian matrix becomes singular and, consequently, obtaining numerical solution becomes difficult.…”
