This paper discusses the importance of microgrids in power systems and introduces a new method for enhancing their performance by improving transient voltage response face disturbances. The involves using hybrid optimization approach that combines driving training-based particle swarm techniques (HDTPS). is used to fine-tune system’s cascaded control scheme parameters, based on proportional–int...

In this paper a new method has been proposed for calculating the frequency-dependent parameters of underground cables. The method uses full-wave formulation for calculating the modal electromagnetic fields and corresponding voltages and currents and then extracting frequency-dependent per-unitlength parameters of underground cables. The proposed method can be used for any cross-sectional shape ...

In this paper, expressions of the neutral conductor current in three-phase networks with compact fluorescent lamps (CFLs) are obtained from a CFL “black-box” model proposed in the literature. These expressions allow studying and performing a sensitivity analysis of the impact of CFLs on neutral current. The influence of CFL model parameters, as well as supply voltage unbalance, number of CFLs p...

Over the years, high voltage transmission of large energy blocks over long distances has widely developed from Line Commutated Converter (LCC) technology. However, continuous expansion AC network and increase in renewable penetration leads to weakening Electric Power Systems (EPS), causing operational problems for LCC-HVDC. This paper evaluates degree contribution VSC-HVDC on LCC-HVDC dynamic p...

This article introduces a new time-domain fault location algorithm for two-terminal parallel transmission lines connected to large scale wind farms. The proposed employs only half-cycle data window of synchronized current samples at both line terminals avoid inaccurate estimation phasors due the generated sub- and inter-harmonics currents by does not need any transformation method decouple doub...

Fault current limiters are essential devices used to protect the power system and its equipment against high levels of fault current, which growing up due increase new sources. This paper proposes a novel design Hybrid Superconducting Current Limiter (Hybrid SFCL), is composed basically by thyristors in series with superconducting element. branch connected parallel an air-core reactor, improves...
