The transformerless PV inverters are the major functional units of modern grid-connected PV energy production systems. In this paper, a new optimization technique is presented for the calculation of the optimal types and values of the components comprising a transformerless PV inverter, such that the PV inverter Levelized Cost Of the generated Electricity (LCOE) is minimized. The proposed metho...

This paper proposed a transformer less inverter for use in residential solar energy systems. There is a strong trend in the photovoltaic (PV) inverter technology to use transformerless topologies in order to acquire higher efficiencies combining with very low ground leakage current. The operation principle, control strategy and characteristics of the system are described. The new and traditiona...

The optimal placement of STATic synchronous COMpensator (STATCOM) for voltage stability improvement in power system is the important optimization problem. There are so many research works are carried out in the optimal placement of STATCOM to achieve the various objectives using Particle Swarm Optimization (PSO). In conventional optimization technique the weight-age of objective functions are c...

This paper introduces an approach to detect the existence of the faulted switch, identify which switch is faulty, and reconfigure the STATCOM. This approach is illustrated on an elevenlevel STATCOM and the effect on the dynamic performance and the total harmonic distortion (THD) is analyzed Many static synchronous compensators (STATCOMs) utilize multilevel converters due to the following: 1) lo...

This paper introduces a multilevel STATCOM for electric arc furnace power quality enhancement. An eleven level cascaded multilevel converter is used to alleviate the impacts of an unbalanced arc furnace load. The STATCOM provides a power electronic-based means of embedded control for reactive power support.

facts technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. statcom is oneof the most important facts devices used in the parallel compensation, enhancing transient stability andetc. since three phase fault is widespread in power systems, in this paper statcom is used...

Results of an investigation on the application of STATCOM for damping subsynchronous resonance (SSR) in a multi-machine system is presented in this paper. For a multi-machine system which has a set of identical parallel turbine-generators or non-identical turbine-generators having torsional modes of the same frequency, generators may suffer from the same mode of torsional interaction correspond...

The STATCOM (Synchronous Static Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution systems. The STATCOM can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the STATCOM, which will result in the under reaching or over ...
