Power oscillation damping controller is designed in linearized model with heuristic optimization techniques. Selection of the objective function is very crucial for damping controller design by optimization algorithms. In this research, comparative analysis has been carried out to evaluate the effectiveness of popular objective functions used in power system oscillation damping. Two-stage lead-...

We discuss the phenomenology of damping signatures in the neutrino oscillation probabilities, where either the oscillating terms or the probabilities can be damped. This approach is a possibility for tests of non-oscillation effects in future neutrino oscillation experiments, where we mainly focus on reactor and long-baseline experiments. We extensively motivate different damping signatures due...

Power oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective...

Transverse instabilities in linacs can be controlled by BNS damping, in which the transverse oscillation frequency is chirped from the head to the tail of the bunch. It has been suggested that this technique could be applied to quasiisochronous rings, such as are proposed for a muon collider. We adopt a reduced phase space model, taking averages over transverse coordinates and with proscribed l...

Virtual synchronous generator (VSG) has been a grid-friendly integration control technique for the of grid-connected inverters. However, emulated inertia and damping VSG can also be used in field dc systems. In this article, virtual is proposed to dampen wideband oscillation voltage microgrid. The strategy contributes maintaining operation converter with network. Besides, relationships among da...

We present analytic treatment of the three different dynamic regimes found in quantum-dot laser turn-on and modulation dynamics. A dynamic coupling, and thus density-dependent scattering lifetimes between dots and reservoir, are identified to be crucial for a realistic modeling. We derive a minimal model for the quantum-dot laser dynamics that can be seeded with experimentally accessible parame...

This paper presents a hardware configuration for a long reach robotic arm in which passive dampers eliminate unwanted oscillation. This paper derives and reduces the equations of motion for the proposed configuration; then develops a "realistic" design. Using a single degree of freedom approximation, the paper presents and experimentally verifies equations for the dominant natural frequency and...

This study starts from the proof of Low Frequency Oscillation (LFO) and then points out that there are many ways to study the LFO including its rejection measures. Also in this study one control system is planned in order to regulate voltage at common coupling point (PCC) in where STATCOM is installed. This research present a single-machine infinite-bus system with one static synchronous compen...

The shunt active power filter (SAPF) system oscillation is a massive threat to the security and stability of grid. This study classifies SAPF into two categories according difference in mechanisms. one category caused by resonant characteristics switching noise called external loop amplification. other induced presence capacitor load current for self-excited oscillation. Unlike previous studies...
