This paper presents the development of a testbed for tuning the parameters of Power System Stabilizers (PSS). The main tuning methodology comprises the use of the classic Single Machine Infinite Bus (SMIB) model and the phase compensation method along with the modal analysis approach and the application of the Mean-Variance Mapping Optimization (MVMO) algorithm. This methodology is then improved by...
In this paper, the hardware and software design and implementation are proposed for the wide-area damping control (WADC) strategies. First, the hardware-in-the-loop (HIL) real-time (RT) simulation system based on the RT-Lab is established as the closed-loop test platform for the WADC applied in multi-machine interconnected power system. The hardware, which contains the microcontroller, the peripheral...
Power-hardware-in-the-loop (PHIL) is a simulation tool that can support electrical systems engineers in the development and experimental validation of novel, advanced control schemes that ensure the robustness and resiliency of electrical grids that have high penetrations of low-inertia variable renewable resources. With PHIL, the impact of the device under test on a generation or distribution system...
The Icelandic power system is characterized by two areas that oscillate against each other during stressed system operation, and may lead to an islanding of system. Conventional stabilizing methods are being used to their full capacity, thus new options are being explored to prevent system break-ups. There is potential in exploiting large industrial loads to enhance system stability. In this paper...
The paper describes the use of K-means clustering algorithm to mine the Synchrophasor data from PMUs. PMUs are newly developed tools for monitoring the grid health by measuring grid parameters such as voltage, current, frequency, rate of change of frequency and phase angle with high sample rate and time stamping. The large amount of data produced by PMUs can help the grid operator for stable operation...
The present paper deals with the application of the real time optimal reconfiguration of a radial power distribution system using three Meta-heuristic optimization algorithms; the Biogeography Based Optimization (BBO), the particle swarm optimization (PSO) and the Genetic algorithms (GAO). The main objective is to minimize the active power loss in the whole system while keeping the voltage at each...
Low-frequency, electro-mechanically induced, inter-area oscillations have in the past, posed a serious threat to the stability of interconnected power systems. Wide Area Monitoring, Protection and Control (WAMPAC) systems based on wide-area measurements can be exploited to address the inter-area oscillation problem. This work develops a modular software architecture for a prototype WAMPAC control...
With the advent of Phasor Measurement Unit in Power System a new dimension has been given to power system monitoring and analysis. In this paper simulation of Nonrecursive and recursive DFT phasor estimation algorithm is done using Labview. The algorithm developed in Labview can be used for real time estimation of phasor by integrating with labview compliant data acquisition system like NI ELVIS kit.
This paper proposes an oscillation monitoring tool capable of detecting the emergence of small signal instability events in an online fashion. The tool uses synchronous generator data to extract the damping and frequencies of modes in an online parallel setting. The analysis uses Prony algorithm that is capable of fitting a given set of data into damped exponentials. The uniqueness is based on the...
The real-time execution of grid stability monitoring algorithms are critical to enabling a truly smart grid. However, the combination of a high sampling rate for grid monitoring devices, combined with a large number of devices scattered across a grid, result in very high throughput requirements for the execution of these algorithms. Here we define a centralized hardware and software infrastructure...
