This paper proposes a control scheme to force homogeneity for heterogenous network of the grid-forming (GFM) inverters in power electronics dominated grid (PEDG) to enable their aggregation and coherent dynamic interaction.Increased penetration of the renewable energy in distributed generation (DG) fashion is moving traditional power system to a hi

Transmit beamforming (TBF) has been proposed as an effective approach to enhance the security performance of multiple-input single-output (MISO) wiretap channels.However, this secrecy enhancement comes at some expenses, such as power consumption and the amount of signal processing.In addition, in block fading channels, TBF fails to deliver secure c
