The Danish research project “Secure Operation of Sustainable Power Systems (SOSPO)” is currently being conducted in a collaboration by a group of partners from academia and industry. The focus of the project is on how to achieve secure operation of the power grid as large scale thermal power plants, supplied by fossil fuel, are phased out in favor of noncontrollable renewable energy sources lik...

This paper presents an adaptive wide-area control strategy based on energy function. The proposed method enhances the post-fault oscillation damping capability of Static Var Compensators (SVC) by incorporating load dynamics in controller design that adapts to variations. are obtained using Phasor Measurement Units (PMU) through power and voltage data measurements, which used estimate a Moving A...

Large power system disturbances and their consequences, represent a challenging problem for the power industry and especially for the network system operators, the ones who are responsible for the network operation at large, its security and reliability. This fact has reinforced interest in the new generation of monitoring systems with the aim to gain if possible a precise and maximum knowledge...

We study the communication network of an on-campus active distribution network (ADN) that comprises phasor measurement units (PMUs) connected to medium-voltage transformers. Within stringent time delays and with minimal loss the PMUs periodically transfer fresh measurements through a phasor data concentrator (PDC) to a centralized electrical network state estimator (control point). Due to stric...

Recent advances on synchro phasor measurement along with its regulation by the Operador Nacional do Sistema – ONS brought access to high resolution data rates up one sample per cycle. Electrical power system current, voltage, phase and frequency are collected through Phasor Measurement Units-PMUs stored in Data Concentrators PDCs. Such high-resolution favours new algorithms applications towards...

This paper introduces a new model to improve the wind power plant performance by modeling its reactive demand. It develops probabilistic based on prediction interval help better of demands unit which needs be compensated static VAr compensator (SVC). is made possible use non-parametric neural network (NN) using lower and upper bound estimation (LUBE) method. To avoid instability arising due non...

Energy transition implies a larger share of the intermittent renewable energy sources connected to power grid. These utilities can change their production within short period time, thus, significantly affecting voltage conditions and load flows in This adds complexity achieving required reliability stability system. Proper timely insight into grid parameters plays an important role regulation s...

A novel technique for loss of mains (LOM) detection, using Phasor Measurement Unit (PMU) data, is described in this paper. The technique, known as the Peak Ratio Analysis Method (PRAM), improves both sensitivity and stability of LOM protection when compared to prevailing techniques. The technique is based on a Rate of Change of Frequency (ROCOF) measurement from M-class PMUs, but the key novelt...

A big step forward to improve power system monitoring and performance, continued load growth without a corresponding increase in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in new patterns. These issues, as well as the on-going worldwide trend ...
