This study presents a multi-objective formulation using Particle Swarm Optimization (PSO) approach, for optimal placement and sizing of distributed generation (DG) resources in the power distribution systems in order to minimize the cost of power losses and improve the voltage profile and energy not supplied. The proposed method considers the options of the DGs installation and takes more numbe...

Increasing use of variable speed drives in industry causes harmonic proliferation in industrial power distribution supply system. Harmonic currents generated by the variable speed drives interact with power system impedance to give rise to harmonic voltage distortion. Thus it is essential to analyze, evaluate and introduce appropriate mitigation techniques for harmonic reduction in the power sy...

In the past, Battery Energy Storage System (BESS) is used for primary frequency regulation. As developments in batteries progress, advancement in applications of BESS including the implementation in high power penetration is expected. Load shedding is one of frequency control methods during stand-alone operation, and the performance of frequency control improves in combination with BESS. Howeve...

Hardware protection and control action are two kinds of low voltage ride-through technical proposals widely used in a permanent magnet synchronous generator (PMSG). This paper proposes an innovative clustering concept for the equivalent modeling of a PMSG-based wind power plant (WPP), in which the impacts of both the chopper protection and the coordinated control of active and reactive powers a...

This paper investigates voltage fluctuations caused by the operation of battery energy storage (BES) units which provide frequency response (FR) and fast (FFR) services using a test network based on typical part United Kingdom (UK) mainland system. provides an overview current FR/FFR currently used in UK, summary their modes operation. Using DIgSILENT Powerfactory, introduces simple disturbance...

This paper discusses the power loss minimization problem in asymmetric distribution systems (ADS) based on phase swapping. is presented using a mixed-integer nonlinear programming model, which resolved by applying master–slave methodology. The master stage consists of an improved version crow search algorithm. generation candidate solutions normal Gaussian probability distribution. responsible ...

The pumps in RHPP Bajina Bašta are started via a static frequency converter (SFC). This resulted increased level of higher harmonics within the RHPP. However, it was not known whether operation this SFP could endanger consumers supplied from mentioned distribution transformer. For purpose, is necessary to check possibilities existence parallel resonant circuit, both itself, and part network tha...
