With the high penetration of renewable power in system, inertia level and frequency regulation capability are reduced, system safety facing a major challenge. Considering different support synchronous generators, effect adjustment coefficient units on minimum has been analyzed based sensitivity analysis. A multiobjective constraint unit commitment model considering is proposed, simulation resul...

This article deals with the black-box modeling of synchronous generators based on artificial neural networks (ANN). The ANN is applied to define relationship between excitation and terminal generator voltage values, Levenberg–Marquardt algorithm used for determining weight coefficients. relation made response reference step changes. proposed approach checked using experimental results obtained ...

The rapid growth in renewable energy-based distributed generation has raised serious concerns about the grid’s stability. Due to intrinsic rotor inertia and damping feature voltage (reactive power) control ability, traditional bulk power plants, which are dominated by synchronous generators (SG), can readily sustain system instability. However, converter-based energy sources possess unique prop...

In this paper, an adaptive gain tuning rule is designed for the nonlinear sliding mode speed control (NSMSC) in order to enhance dynamic performance and robustness of permanent magnet assisted synchronous reluctance motor (PMa-SynRM) with considering parameter uncertainties. A surface whose parameters are altering time at first. The proposed NSMSC can minimize settling without any overshoot via...

Abstract The maximum power point operation of the photovoltaics (PV) restricts them to participate in frequency regulation connected system. Therefore, it is a common practice deload PV systems for generating an active reserve. However, deloading causes underrating these systems, hence additional panels are installed overcome reserved power. Since regulations can be achieved by using batteries,...

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...

The most basic electrical machine that converts mechanical energy into is synchronous machines. Synchronous machines can be operated at high speeds and low for different power plants. In terms of system planning, it important to examine the operating characteristics idle variable load conditions in these cycles. It very generators, which are components turbines plants, have efficiency when they...

Brazil is a country with continental dimensions and has power generation system interconnected all regions, through transmission lines (TLs), allowing supply for its all-consumption centers. However, building new TLs may be unfeasible in an environmental financial sense. With the advancement of electronics, FACTS (Flexible Alternating Current Transmission Systems) devices were created, which ar...
