Description
Summary:Voltage stability (VS) has turned into an impending menace for heavily-loaded renewable-rich power systems. This necessitates more intelligent measures to be taken in order to maintain VS of power systems, despite various loads' characteristics and variations of renewable energy resources. Grid integration of large-scale energy storage systems (ESSs) has recently been considered as an effective means of enhancing the efficiency and reliability of power systems. In this paper, the use of ESS devices to dynamically preserve a prescribed level of VS for power systems is investigated. The objectives of this paper are to (i) optimally compute and (ii) dynamically control the required active and reactive power compensation by the ESSs such that a desired voltage stability margin (VSM) is always ensured. The single-contingency criterion has also been considered in this study. The effectiveness of the proposed approach in maintaining the system's short-term VS is evaluated through case studies, considering both constant-power and voltage-dependent loads.
