“…Flexible AC Transmission System (FACTS) devices have been contributing significantly in enhancing power system transient stability (low/high order oscillation) by regulating power flows and enhancing power transfer capacity of transmission system [1]- [3]. Among the multiple FACTS devices, the particular interest of this study is on static synchronous compensators (STATCOM) as this device improves power transfer capability [4], [5], enhances transient stability by regulating voltage [6], ameliorates inter-area oscillation [7] and provides faster and smoother voltage recovery through reactive power compensation [8]. In addition, STATCOM outperforms other FACTS devices in damping power system oscillations [9] and enhancing power transmission capacity in many occasions [10].…”

This paper investigates the enactment of Battery Energy Storage System (BESS) and Static Compensator (STATCOM) in enhancing large-scale power system transient voltage and frequency stability, and improving power export capacity within two interconnected power systems. A PI-lead and lead-lag controlled BESS is proposed for multimachine power system to provide simultaneous voltage and frequency regulation within the defined battery state-of-charge (SOC) ranges and an equivalent Finnish transmission grid is used to evaluate the system performance. According to Australian National Electricity Market (NEM) grid requirements, the performances of the proposed control schemes are compared with conventional PI controlled BESS and STATCOM under multiple temporary and permanent fault conditions. In addition, two adjacent disturbance events are also applied to evaluate system performance with BESS and STATCOM. Through simulation results, it is shown that when there is a 44% increase in power export and the STATCOM fails, incorporating BESS improves the performance and justifies the novelty of this study. Moreover, the proposed lead-lag controlled BESS manifests better transient performance than BESS with PI-lead and traditional PI controller, in the event of divergent temporary and permanent faults.

“…The fault clearing time (FCT) is set at random in a power system, hence, if the FCT is more than CCT, the system losses synchronism. A robust power system is largely determined by its response to disturbances; therefore, a high value of CCT indicates a robust power system [3]. The Nigerian 330-kV grid network is faced with series of challenges like voltage instability, long transmission lines, nature of transmission lines, high power losses [4], coupled with constant power demand increase and lack of sensitive equipment to detect and stabilize their challenges [5].…”

Assessment of the dynamic response of generators, within a power system, when subjected to various disturbances, has been a major challenge to power system researchers and engineers for the past decades. This paper investigates the dynamic response of the generators in the Nigeria 330-kV grid network when a balanced 3-phase fault is applied with the aim of determining the Critical Clearing Time (CCT) of the transmission network. The generalized swing equations for a multi-machine power system is presented. MATLAB software is employed as the tool for the simulations. A real network of Nigeria 330-kV electric grid is used as a case study. The result obtained clearly show that there exist critical buses such as Benin, Onitsha and Jebba Transmission Station (TS) and critical transmission lines such as Benin-Olorunshogo Generating Station (GS) and Jebba TS-Shiroro GS within the network. The results also reveal that the system losses synchronism when a balanced 3-phase fault is applied to these identified critical buses and lines. The results further indicate that the Nigeria 330-kV transmission network is on a red-alert, which requires urgent control measures with the aim of enhancing the stability margin of the network to avoid system collapse.
