Obtaining Feasibility of Power Flows in the Deregulated Electricity Market Environment
Published by Mariusz DRABECKI, Eugeniusz TOCZYŁOWSKI,Warsaw University of Technology, Institute of Control and Computation Engineering Abstract. In this paper we analyse a power dispatch method for obtaining feasible power flows, both active and reactive power, in terms of satisfying the transmission, voltage level and voltage angles’ constraints, under assumption that supply of electric power isContinue reading “Obtaining Feasibility of Power Flows in the Deregulated Electricity Market Environment”
Steps to Find the Source of Harmonics
Published by David Horning, November 2014. Power Monitors, Inc., White Paper: Steps to Find the Source of Harmonics Abstract. Harmonics are “Non-Linear” current or voltage in an electrical system. Any waveform that deviates from a perfect sine wave has harmonics. Any nonlinear load draws harmonic currents and therefore produces harmonic voltage distortion, by producing non-sinusoidalContinue reading “Steps to Find the Source of Harmonics”

Review on Techniques of Optimal Placement and Sizing of DG in Distribution Systems
Published by Veeraraghavulu vemula1, R. Vanitha, sathyabama2, institute of science and technology , India. ORCID: 1. 0000-0001-5872-8537 2. 0000-0003-2195-7242 Abstract: Distributed generation (DG)is a term describing the generation of the electricity use on other side rather than transmitting energy over the electric grid. By using this (Distribution generation) DG in power system plays a majorContinue reading “Review on Techniques of Optimal Placement and Sizing of DG in Distribution Systems”
