Probabilistic assessment of voltage stability margin (VSM) with existence of correlated wind speeds is investigated. Nataf transformation is adopted to establish wind speed correlation (WSC) model. Based on the saddle-node bifurcation transversality condition equations and Monte Carlo simulation technique, probability distribution of VSM is determined. With correlation coefficients range low to...

The increasing number of megawatt-scale photovoltaic (PV) power plants and other large inverter-based stations that are being added to the system leading changes in way grid is operated. In response these changes, new code requirements establish should not only remain connected during faulty conditions but, also provide dynamic support. This feature referred literature as momentary cessation op...

although lcl filters are used widely in the grid connected inverters to reduce high-orderharmonics, such a system increases system order and therefore sustainable design of closed-loopcontroller system will be complicated. recently, the single-loop control strategy has beensuggested for l or lc filter based grid-connected inverters. however, the use of single-loopcontrol directly in lcl filter-...

This paper presents a hybrid algorithm by applying firefly and particle swarm optimization (HFPSO) to determine the optimal sizing of distributed generation (DG) distribution static compensator (D-STATCOM) device. A multi-objective function is employed enhance voltage stability, profile, minimize total power loss radial system (RDS). Firstly, stability index (VSI) applied locate location DG D-S...

A tunable transformer-based Q-enhancement method for monolithic inductors used in parallel resonant LC tanks is presented. The Q of the inductor that forms the transformer primary is enhanced by cancelling the voltage drop across the series loss resistance of the primary with a voltage of opposite polarity that is induced by a current in the secondary. The circuit allows dc voltage control of Q...
