“…The figure shows that the accuracy level has been achieved in less than 5 s. The solar integrated system is then analyzed for contingency conditions with and without IPFC. The tuning of IPFC has been performed using the Firefly algorithm [18]. The time elapsed for the tuning is 232.59 s. The improvement in the accuracy in result by Firefly Algorithm is shown in Figure 8.…”

In these post COVID times, the world is going through a massive restructuring which India can use to its benefit by attracting foreign industrial investment. The major requirement is a reliable and ecofriendly electrical power source. Of late, renewable energy sources have increasingly become popular as alternative source of electricity. They can provide immense aid in improving the reliability of the power system, when placed properly. The alternative integrated energy sources along with FACTS devices can provide a promising future for reliable power systems. In this paper, an effective location for the solar power unit and Interline Power Flow Controller using Line Severity Index is proposed in order to avoid contingencies. An Indian 62 bus system and IEEE 57 bus system are considered for the study. The Firefly algorithm is used to tune the IPFC in the Integrated Energy Systems scenario, for a dual objective function. The effect of placement of the solar unit and the optimized IPFC is analyzed and studied in detail in this paper.

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.

This paper investigates the application of large-scale solar photovoltaic (SPV) system for voltage stability improvement of weak national grids. Large-scale SPV integration has been investigated on the Nigerian power system to enhance voltage stability and as a viable alternative to the aged shunt reactors currently being used in the Nigerian national grid to mitigate overvoltage issues in Northern Nigeria. Two scenarios of increasing SPV penetration level (PL) are investigated in this work, namely, centralized large-scale SPV at the critical bus and dispersed large-scale SPV across the weak buses. The voltage stability of the system is evaluated using the active power margin (APM) also called megawatt margin (MWM) derived from Active Power–Voltage (P–V) analysis, the reactive power margin (RPM) and the associated critical voltage–reactive power ratio (CVQR) index obtained from Reactive Power–Voltage (Q–V) analysis. All simulations are carried out in DIgSILENT PowerFactory software and result analyses done with MATLAB. The results show that with centralized SPV generation for the case study system, the highest bus voltage is able to fall within acceptable limits at 26.29% (1000 MW), while the dispersed SPV achieves this at 21.44% (800 MW). Also, the dispersed SPV scenario provides better voltage stability improvement for the system as indicated by the MWM, RPM and the CVQR index of the system. Therefore, this work provides a baseline insight on the potential application of large-scale SPV in weak grids such as the Nigerian case to address the voltage stability problems in the power system while utilizing the abundant solar resource to meet the increasing energy demand.
