Multi‐level refined power system operation mode analysis: A data‐driven approach

Degree of Optimality as a Measure of Distance of Power System Operation from Optimal Operation

This paper presents an algorithm based on inter-solutions of having scheduled electricity generation resources and the fuzzy logic as a sublimation tool of outcomes obtained from the schedule inter-solutions. The goal of the algorithm is to bridge the conflicts between minimal cost and other aspects of generation. In the past, the optimal scheduling of electricity generation resources has been ...

A Direct Power Feeding System for AC Railway Networks Using Modular Multilevel Converter

Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...

Sliding Mode Control of Multilevel Power Converters

The application of sliding mode, a non-linear robust and self-contained approach, to the control problem of electronic power converters, is outlined and illustrated. On-line sliding mode control is suited to multilevel power converters as they are inherently variable structure systems. Obtained controllers are robust concerning parameter variation and perturbations and provide "Just In Time" sw...

Power Grid Dynamics: Enhancing Power System Operation through Prony Analysis

Prony Analysis is a technique used to decompose a signal into a series consisting of weighted complex exponentials and promises to be an effi cient way of recognizing sensitive lines during faults in power systems such as the U.S. Power grid. Positive Sequence Load Flow (PSLF) was used to simulate the performance of a simple two-area-four-generator system and the reaction of the system during a...
