In recent years, there has been growing interest of synchrophasor measurements like Phasor Measurement Units (PMUs) Power systems are now being gradually populated by PMU since they provide significant phasor information for the protection and control of power systems during normal and abnormal situations. There are several applications of PMUs, out of which state estimation is a widely used. T...

Evaluating performance of PMUs to verify the consistency of phasor measurements is of a great importance since it promotes the interoperability among PMUs from different manufacturers. This paper presents a set of test methodology and tools for evaluating the dynamic performance of PMUs when exposed to a step change of input signals. A phasor estimation scheme is proposed to achieve high accura...

The aim of the article is a study undertaken to determine the optimal locations of phasor measurement units (PMUs) for a given power system. Power systems are rapidly becoming populated by PMUs. PMUs have multiple uses at substations. They provide valuable phasor information for protection and control of power systems during abnormal operation. Under normal operations, they also help in monitor...

This paper introduces a new nonlinear control of flexible ac transmission systems (FACTS) controllers for the purpose of damping interarea oscillations in power systems. FACTS controllers consist of series, shunt, or a combination of series-shunt devices which are interfaced with the bulk power system through injection buses. Controlling the angle of these buses can effectively damp low frequen...

This paper presents a new method for transient stability assessment of power systems using kernel principal component analysis (KPCA) and Gaussian process (GP). Considering the possible real-time information provided by PMU, a group of system-level classification features are firstly extracted from the power system operation condition to construct the original feature set. Then KPCA is used to ...

In recent years, the electrical substations are experiencing a rapid transition towards fully digital measurement infrastructure, in terms of data acquisition, storage and processing. The IEC Std 61850-9-2 defines format, also known as Sampled Value (SV), to be employed by instrument transformers, merging units, controller devices. this scenario, it is reasonable expect that Phasor Measurement ...
