The deployment of a synchrophasor-based widearea measurement system (WAMS) in a power grid largely improves the observability of power system dynamics and the operator's real-time situational awareness for potential stability issues. The WAMS in many power grids has successfully captured system oscillation events, e.g. poorly damped natural oscillations and forced oscillations, from time to time. To identify the root cause of an observed oscillation event for further mitigation actions, many methods have been proposed to locate the source of oscillation based on different ideas and principles. However, most methods proposed so far for locating the oscillation source in a power grid are not reliable enough for practical applications. This paper presents a comprehensive review of existing location methods, which basically fall into four major categories, plus a few other methods. Their advantages and disadvantages are discussed in detail. Some trends and challenges on the problem of oscillation source location are pointed out along with potential future research directions. Finally, a practical, general scheme for oscillation source location using available location methods is suggested and analyzed.

“…In order to avoid arbitrary objective functions as in the optimization-based procedures, we have previously used the concept of oscillation energy [28], [29] and a new dynamic performance measure called total action (TA) [30], [31]. To not rely on targeted modes and to offer adaptability to changing conditions, we are now proposing an adaptive coordination that works on top of the traditional decentralized control; through this coordination, decentralized controllers are not required for a global-wide parameter re-turning.…”

This paper introduces the concept of adaptive coordination of damping controllers for enhancing power system stability. The coordination uses phasor measurement units (PMUs) to adapt to different disturbances by selecting the switching status (on/off) of damping controllers that minimizes an energy-based dynamic performance measure. This dynamic performance measure, referred to as total action (TA), uses a physical interpretation of excited modes rather than fixed targeted modes as in the traditional damping control design. The coordination is formulated as a binary integer programming problem, which is solved by using the total action sensitivity (TAS). The concept of oscillation energy and the implementation of the adaptive coordination scheme is tested in the western North America power system (wNAPS). The results show that the proposed adaptive control scheme can improve oscillation damping for different short-circuit locations even in the presence of large communication delays.

“…A different approach to study electromechanical oscillations consists of analyzing the kinetic oscillation energy of each machine by comparing the phase of selected energy modes to identify energy exchanges paths [9], [10]. Recent efforts also consider the distribution of the kinetic energy, branch potential energy [11] and the idea of energy dissipation and its relationship with oscillation damping [12].…”

This paper describes a novel approach to analyze and control systems with multi-mode oscillation problems. Traditional single dominant mode analysis fails to provide effective control actions when several modes have similar low damping ratios. This work addresses this problem by considering all modes in the formulation of the system kinetic oscillation energy. The integral of energy over time defines the total action as a measure of dynamic performance, and its sensitivity allows comparing the performance of different actuators/locations in the system to select the most effective one to damp the oscillation energy. Time domain simulations in the IEEE 9-bus system and IEEE 39bus system verify the findings obtained by the oscillation energy based analysis. Applications of the proposed method in control and system planning are discussed.
