This paper proposes a method for minimizing the inductor current ripple of DC–DC converter in two-stage power conversion system consisting grid-connected PWM and an interleaved multiphase three-level converter. To reduce output voltage ripple, is configured parallel operated interleaved. However, circulating generated by operation increases each causes loss saturation. In this paper, three-phas...

This article presents a Lagrange multiplier-based adaptive droop control to mitigate distribution power loss of parallel-connected distributed energy resource (DER) systems in dc microgrids. The comprising line and converter can be modeled as quadratic function the output currents DER systems, which optimized by tertiary-layer multiplier method obtain optimal current references for secondary-la...

A new approach to the design of decentralised controllers, using Multi-Objective Evolutionary Algorithm (MOEA), for load-frequency control of interconnected power systems with AC-DC parallel tie-lines and considering Governor Dead Band and Generation Rate Constraint nonlinearities, is proposed in this paper. The HVDC link is used as system interconnection in parallel with AC tie-line to effecti...

A new design of Multi-objective Evolutionary Algorithm based decentralized load-frequency controllers for interconnected power systems with AC-DC parallel tie-lines, is proposed in this paper. HVDC link is connected in parallel with the existing AC link for stabilizing the frequency oscillations of AC system. The proposed controller fulfills two main objectives, namely, minimum Integral Squared...

This article explores a nonlinear, adaptive controller aimed at increasing the stability margin of direct-current (dc), small-scale, electrical network containing an unknown constant power load (CPL). Due to its negative incremental impedance, this reduces effective damping network, which may lead voltage oscillations and even collapse. To overcome drawback, we consider incorporation controlled...

Type I interferon (IFN-I) have emerged as crucial mediators of cellular signals controlling DC differentiation and function. Human DC differentiated from monocytes in the presence of IFN-α (IFN-α DC) show a partially mature phenotype and a special capability of stimulating CD4+ T cell and cross-priming CD8+ T cells. Likewise, plasmacytoid DC (pDC) are blood DC highly specialized in the producti...
