AC-DC hybrid grid analysis

“An AC/DC hybrid power grid analysis algorithm is a computational tool that can be used to model and simulate the behavior of AC/DC hybrid power grids under various operating conditions. This algorithm is designed to analyze the performance of the system, identify potential issues, and optimize the operation of the system to ensure its reliability and stability. The AC/DC hybrid power grid analysis algorithm takes into account various factors such as power flow, voltage stability, and fault analysis. It can also be used to analyze the impact of renewable energy sources on the system and evaluate the effectiveness of energy storage systems. By using an AC/DC hybrid power grid analysis algorithm, utilities can identify potential issues in the system, such as voltage fluctuations, harmonic distortions, and power imbalances. This algorithm can also help to optimize the operation of the system, by minimizing losses, reducing the cost of energy transmission, and improving the efficiency of the system. The use of an AC/DC hybrid power grid analysis algorithm is becoming increasingly important as more renewable energy sources are integrated into the electrical grid. By using this algorithm, utilities can ensure the reliable and efficient operation of the electrical grid, while also supporting the transition to a more sustainable energy future.”

My research focus on developing Fault, Stability, Power flow algorithm for AC-DC hybrid grid. From this research, I anticiapte the enhancement of power grid resillience, power system stability enhancement, low carbon emission (i.e., net zero).

“In an electric power system, a fault or fault current is any abnormal electric current. For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker (…) The design of systems to detect and interrupt power system faults is the main objective of power-system protection”

“Power system stability refers to the ability of a power system to move from one steady-state operating point following a disturbance to another steady-state operating point, without generators losing synchronism or having unacceptable voltage magnitude and frequency deviations”

“The power flow is the basic tool for investigating these requirements. (…) Conventional nodal or loop analysis is not suitable for power flow studies because the input data for loads are normally given terms of power, not impedance. (…) The power flow problem is therefore formulated as a set of nonlinear algebraic equations suitable for computer solution”
