Grid control using password base authentication system with automation using ardino

These days, societies became very advance, all want security so in this project we show, how to control power distribution  #GSS(gride substation )  and PSS(power substation) using password base

 In this project, we showed how to control GSS and PSS by password:-

Wind/PV Hybrid System using MATLAB-Simulink

 In the last few years, because of high depletion of conventional energy resources and environment concerns, the renewable energy resources are becoming more important all over the world. Among different renewable energy sources, wind and solar energy sources are most promising. Since the oil crisis of the early 1970s, the utilization of solar and wind power has become increasingly noteworthy, popular and cost-effective. But the main disadvantage of solar and wind energy system is that it depends on seasonal variation and it is unpredictable in nature. As both wind and solar energy sources are not consistent and non-stable in nature. A hybrid system of wind and PV power sources provides a stable form of power generation. Hybrid energy systems are cost effective energy solutions with high reliability and power quality. Individual photovoltaic (PV) or wind energy system, do not generate utilizable energy for a large portion of time during the year. This is because of dependency on variable sunshine hours in PV system and on relatively high cut-in wind speeds. In this paper individual modeling of PV and wind energy system is done and studied in Matlab/Simulink software.
