Power System Optimization and Stability

The increase in the need for electrical energy day by day causes the number of connections in the network to increase and planning becomes more difficult. The power flow analysis is an integral part of the work carried out on the power systems and it is can easily be performed thanks to the increased speed and capacit…

The rapid development of distributed generators (DGs) has increased the complexity of distribution system (DS), creating a need for advanced solutions to maintain operational constraints.

The proposed AGC remains fully operational throughout grid splitting, maintaining independent control over each separated area and supporting the transition toward reconnection t…

In this study, a test signal proposed in the literature for amplitude and phase estimation of harmonics in power systems is utilized. The test signal is applied to the proposed Kalman-based approach under noise conditions of 10 dB, 20 dB, and 40 dB. Performance is evaluated by comparing the obtained estimation results…

A classification system using deep learning for detecting power quality disturbances (PQDs), which are commonly experienced in electric power systems, has been proposed in this study. Because reliable and efficient classification methods are becoming increasingly critical as new forms of energy are integrated into the…

The accurate and efficient resolution of the power flow problem is crucial for planning, operating, and controlling power systems. While conventional iterative methods are commonly used, they often experience incomplete or slow convergence. This has prompted an increasing interest in meta-heuristic optimization techni…

Recent developments and trends in power systems have increased the importance of dynamic modeling and monitoring of system components. Increased penetration of renewable energy sources and battery storage systems makes grid operation challenging. Being environment-friendly and fast-responding, hydroelectric power plan…

Post-disaster power restoration is essential for ensuring the continuity of critical infrastructure, emergency response, and societal functions. A key challenge in this process is the black-start problem, which involves restoring a power grid from a complete shutdown under uncertainty about component failures. Traditi…

Eccentricity faults in electric machines remain a critical concern, as they generate uneven magnetic forces that increase vibration and noise, ultimately raising the risk of premature motor failure. This study proposes a method for the early detection of dynamic eccentricity (DE) faults in hydropower plants through an…
