Increased needs for electrical energy as well as environmental concerns besides growing attempts to reduce dependency on fossil fuel resources have caused power system industries to set an ambitious target of renewable generation. Therefore, the capacity of installed inverterbased distributed generators (DGs) and renewable energy sources (RESs), individually or through the microgrids (MGs), in power systems is rapidly growing; and this increses the significance of renewable integrated power system stability and control as a challenging issue. It is well known that low penetration of MGs/DGs has little influence on host grid stability and dynamics and thus the associated dynamics could be studied through simple power flow analysis. However, modern power grids face new technical challenges arising from the increasing penetration of power-electronic-connected MGs/DGs. Increasing renewable power penetration level may adversely affect frequency response and voltage and system control, and lead to degraded performance of traditional control schemes. This, in turn, may result in large deviations and, potentially, system instability. This presentation delas with frequency stability assesment of inverter-based integrated power systems. Details of the talk could be found in the recently published book “Renewable Integrated Power System Stability and Control” by WileyIEEE.
