This paper proposes a phasor representation of electrical networks by using bond graph methodology. A so-called phasor bond graph is built up by means of two-dimensional bonds, which represent the complex plane. Impedances or admittances are used instead of the standard bond graph elements. A procedure to obtain the steady-state values from a phasor bond graph model is presented. Besides the pr...

The awareness of the state of the power grid, such as voltage magnitude, frequency and phasor angle is critical to maintain reliable and stable operations of the power grid. Synchronized by a common timing source, synchrophasors measure the electrical waves on power grids. The collected data are transmitted to the central server for further data processing and analysis, such as abnormal event d...

This paper presents optimal phasor measurement units (PMUs) placement algorithms for power system observability. The optimal placement problem (OPP) is formulated such that minimizing the number of PMU installations for full network observability. Three approaches, in this paper, are introduced aiming at reducing the computational burden in Optimal Placement problems. Depth First Search, Simula...

Present power systems operate in more and more difficult conditions generated by various physical and economic factors. Pushing the power system closer to its physical limits worsens the reliability and security of the general operating conditions. Hence, a better control across the entire grid, through more intensive online analysis is needed. At present, a common point of view considers that ...

Recent advancements in Ising machines, both via quantum and quantum-inspired annealing, have been showing promising results solving difficult optimization problems. Due to the potential of these dedicated there is a rising interest applying machines power system operation. However, despite exhibiting computational advantages over conventional resources, modeling capability limit applications. H...

The social economy is growing rapidly, and the power grid load demand increasing. To maintain stability of grid, it crucial to achieve accurate rapid system assessment. In actual operation network, data loss an unavoidable situation. However, most data-driven models currently used assume that input complete, which has obvious limitations in real-world applications. This paper suggests IVS-GAN m...

This paper proposed wavelet-based design using Discrete Wavelet Transform to compress smart grid electrical signals and reduce noise. For the Smart Grid’s smooth functioning, power signal must be monitored, proper actions taken quickly for any abnormality. The compressed data takes less time communicate disturbances. is tested phasor measurement unit, which monitors records status of hence circ...

This paper presents a method for designing minimal measurement set that include both Supervisory Control And Data Acquisition (SCADA) and Synchronized Phasor Measurements Units (SPMU) data for a Hybrid State Estimation (HSE). The optimal location of Phasor Measurement Units (PMU) is performed by Binary Integer Linear Programming (BILP). Among these PMUs, the highest priority indexed PMUs are se...
