Relays
Data used to produce figures 5-7 in the paper Multi-Gate In-plane Actuated NEMS Relays for Effective Complementary Logic Gate Designs as well as tables 1 and 2. Figure 5 shows input and output data collected from a 3-input NAND gate comprised of a novel multi-gate (multi-input relay). Figures 6 and 7 present data from COMSOL simulations indended to outline a procedere for optimizing these relays and allow for scaling of the device parameters. Table 1 compares our designs with those of other works, in terms of number of relays and critical path. Table 2 compares the parameters

This work presents a novel Anti-Islanding (AI) protection of Photovoltaic (PV) Systems based on monitoring the dc-link voltage of the PV inverter. A PV System equipped with AI protection like frequency relays, a rate of change of frequency (ROCOF) relay, and respectively the proposed dc-link voltage relay is simulated under the conditions of islanding and the detection time for all these AI techniques are compared. The study shows under which conditions our proposed dc-link voltage AI relay is the most efficient.

This work presents a Matlab/Simulink study on anti-islanding detection algorithms for a 100kW Grid-Connected Photovoltaic (PV) Array. The main focus is on the islanding phenomenon that occurs at the Point of Common Coupling (PCC) between Grid-Connected PV System and the rest of the electric power system (EPS) during various grid fault conditions. The Grid-Connected PV System is simulated under the conditions of islanding, and anti-islanding (AI) relay reaction times are measured through the simulation.
