Keywords:
Electricity supply, Frequency regulation, Photovoltaic (PV) cells, Power grid stability, Voltage controlAbstract
This study presents a comprehensive MATLAB power grid stability analysis, focusing on voltage, frequency, small-signal, and transient stability. The IEEE 14-bus and 30-bus test systems are used as case studies. MATLAB's Power System Toolbox and Simulink simulate and analyze the grid's behavior under various operating conditions. Power grid stability is a critical concern for ensuring electricity's reliable and continuous delivery. This study analyzes power grid stability using MATLAB, focusing on transient, voltage, and frequency stability. The analysis is performed on a representative power system model that includes multiple generators, transmission lines, and load nodes. The system's response to various disturbances, such as sudden load changes, faults, and generator outages, is evaluated using time-domain simulations. MATLAB's power system toolbox and custom scripts perform dynamic simulations and stability assessments. Key parameters such as rotor angle deviations, voltage profiles, and frequency oscillations are analyzed to determine the grid's ability to maintain stable operation under various operating conditions. The results demonstrate the effectiveness of MATLAB as a tool for modeling and assessing power grid stability, providing insights into potential vulnerabilities and suggesting mitigation strategies for improving grid resilience. This study presents a comprehensive MATLAB power grid stability analysis, focusing on voltage, frequency, small-signal, and transient stability. The IEEE 14-bus and 30-bus test systems are used as case studies.
