Co-Optimization of Ancillary Services Providing Primary Frequency Control in the Day-Ahead Market
IEEE AccessLarge-scale integration of inverter-based resources (IBRs) challenges primary frequency control because IBRs don’t typically respond to frequency fluctuations, which is partially due to a lack of financial incentives.

International Journal of Electrical Power & Energy SystemsThe high penetration of photovoltaic (PV) in power grids typically leads to the displacement of traditional synchronous generators (SGs). However, with a high penetration of PV, fewer SGs are running, and the sharing of responsibility to control the ...
