by minimizing the total potential energy function and deploying the virtual work principle, a higher-order stiffness matrix is achieved. this new tangent stiffness matrix is used to solve the frame with geometric nonlinear behavior. since authors’ formulation takes into account the higher-order terms of the strain vector, the convergence speed of the solution process will increase. in fact, bot...

This paper investigates the performance analysis of various Multicarrier Pulse Width Modulation strategies with Sinusoidal reference for single phase seven level diode clamped Z-source inverter designed with two intermediate Z-source networks connected between the input source and inverter circuit. The diode clamped Z-source based MLI strategy enhances the fundamental output voltage and reduces...

To meet the challenge of large-scale renewable energy penetration and take full advantage of existing AC infrastructure, the bipolar DC distribution system is of interest. In this article, the system structure and characteristics of the bipolar DC distribution network are proposed. The three-level Neural Point Clamped Converter (NPC) is used in the proposed system to construct the bipolar DC sy...

Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...

In a conventional AC distribution system, the conservation voltage reduction (CVR) strategy is widely employed to lower down of specific load power consumption. The wide applicability demand side management (DSM) using CVR in stand-alone microgrid through VSI-based energy sources thrust area, that is, not examined yet and needs be explored. fast dynamics flexible control are characteristics vol...

cell replacement therapy has provided the basis for future clinical applications to treat central nervous system injuries fallowing by car accidents. induced functional neurons are an option for replacing the lost neurons. the ability to monitor changes in membrane potential is a useful tool for studying neuronal function, but there are only limited options available at present. here, investiga...

In this paper, we propose a novel distributed formation control strategy, which is based on the measurements of relative position of neighbors, with global orientation estimation in 3-dimensional space. Since agents do not share a common reference frame, orientations of the local reference frame are not aligned with each other. Under the orientation estimation law, a rotation matrix that identi...
