The main goal of this paper is to study statistical indices and evaluate AGC indices in power system which has large penetration of the WTGs. Increasing penetration of wind turbine generations, needs to study more about impacts of it on power system frequency control. Frequency control is changed with unbalancing real-time system generation and load . Also wind turbine generations have more flu...

Lightning location systems (LLS) provide data on lightning activity such as type, GPS location, exact time of the stroke, current amplitude, measurement error, etc. The proper application LLS using customized software support can be a powerful decision-making tool in control, maintenance and development power systems. utilization requires with specific functionalities. Software functionalities ...
