Abstract:   (128 Views)
Analyzing power systems for network planning and operation requires a thorough understanding of network parameters to evaluate system performance. Effective monitoring and management depend on power flow analysis and contingency assessment. This paper examines an electric power system with a focus on these critical aspects to enhance planning and operational efficiency. A regional transmission network is used as a case study, with simulations conducted using Power System Simulation (PSS) software. The network’s performance under various N-1 contingency cases was evaluated, emphasizing voltage stability and line loading violations. Vulnerable buses were identified through separate voltage and line loading violation analyses. This study also examines the interaction between STATCOM and the network during N-1 contingencies, demonstrating its effectiveness in improving voltage stability and reducing overloads. To assess voltage collapse proximity and outage effects on reactive power margin, QV curves were plotted for the most affected buses. STATCOM was placed at each affected bus to determine optimal performance, mitigating N-1 contingency effects. By effectively compensating for reactive power, the network’s power handling capacity was enhanced. Consequently, applying STATCOM significantly improved voltage profiles and increased the power handling capacity of affected buses before and after contingency scenarios, ensuring a more stable and resilient transmission network.
Keywords: Contingency analysis, Network Planning, Power system operation, Power system simulation (PSS), Voltage collapse.
