Abstract: The integration of Renewable Energy Sources (RES) into power grids presents significant challenges, particularly concerning transient stability. This study focuses on analysing the transient stability of an RES-dominated power grid, with a focus on solar PV systems. The work aims to evaluate the impact of varying irradiance levels on the grid and analyse their transient stability response under transient events. It equally identifies the system vulnerabilities and evaluates the effectiveness of possible strategies for enhancing transient stability in solar power systems. The work....,

Abstract: In Big data and Deep learning structure involve complex computation including sequential matrix multiplication which may reduce overall system clock period. Whereas FPGA offers the parallel processing and hardware acceleration. In this project, implement the matrix multiplication process of the CPU part on the PYNQ-Z2 FPGA development board to design a matrix multiplication accelerator. A custom matrix multiplication IP core was developed using Vitis HLS and integrated with the PYNQ framework for the design. By the offloading computation and parallel process nature of the FPGA, the hardware-software system achieves improved performance in terms of timing analysis compared with sequential processing on CPU framework.

Abstract: In this analysis, we present a technique to minimize the reactive components (capacitors and inductances) of rectifiers with near sinusoidal input currents (RNSIC) by 15%–25%. Two RNSIC converters of the same kind, dimensioned for half of the converted nominal power and whose entrance currents are phase-shifted with an angle of 30° to 40° by carefully selecting the inductances on the AC portion, are connected in parallel in this approach. Therefore, lowering the capacitors and inductances of the two rectifiers results in an adequate compensation of the type 5 current harmonics created in the power grid.......

Abstract: Background: The global transition to electric mobility and volatile supply chains poses major challenges [6,7]. EV batteries demand high energy density, fast charging, long cycle life, and precise SOC/SOH estimation amid sensor noise [2], while networks must absorb disruptions and curb bullwhip effects.
