This paper presents a novel concept of utilizing the photo voltaic solar farm inverter as STATCOM(Static Compensator), named PV-STATCOM, in order to improve the voltage profile of the power system. The entire STATCOM is able to transmit either active or reactive power into the grid. This system is connected to a 14 BUS IEEE standard grid as a case study to simulate the performance of the system...

Two generic configurations of forced commutated PWM converters, i.e. voltage source inverters and current source inverters, have been proposed as advanced reactive power compensators'. A new configuration to combine the features of the two generic ones is proposed, designed and analyzed in this paper. It is composed of a PWM current source inverter handling high power with very low switching fr...

nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. common techniques applied for harmonics measurement and assessment such as fft have significant errors in presen...

This paper studies a Fuzzy Logic Control Based (FLCB) Shunt Active Filter (SAF) capable of reducing the total harmonics distortion (THD) in Power System (PS). SAF is one of the key controllers in Flexible Alternating Current Transmission System (FACTS) to control the transmission line voltage and can be used in PS to enhance the power transmission capacity and extend the transient stability. In...

ABSTRACT The control of renewable energy in electrical power system is investigated with the integration. The generation of electrical energy from renewable energy sources is fed to the grid after conversion by DC/AC converter. For compensation of current unbalance, load reactive power demand, load neutral current and load current harmonics etc, shunt active power filter are used. With the comb...

The objective of optimal feeder reconfiguration of radial distribution system problem is to obtain the best set of branches to be opened, one each from each loop, such that the resulting radial distribution system has the desired performance. This paper presents a feeder reconfiguration problem in the presence of distributed generators to minimize the system power loss while satisfying operatin...

Nowadays, the usage of load emulators, is the best method for implementation and analysis of different electrical load change scenarios in laboratories. This paper presents an improved programmable load emulator which can emulate both reference active and reactive power simultaneously. The proposed control system can track the dynamic load changes rapidly and accurately in addition to pulse cha...

Ac to DC converter is used for operating DC electrical machine and also supplies DC power to battery which is used for many purposes. The main purpose of this project is to compensate the harmonics by using harmonic current compensation and reactive power control. If reactive power is compensate prior to system then non linearity or harmonics present in the system does not much affect the exist...
