Abstract:As the amount of new energy injected into the power system increases, the system inertia decreases and the spatio-temporal characteristics become apparent. Due to the uneven distribution of inertia in the power system, the dispersion of the frequency response after disturbance is more pronounced, and the inertia estimation error has a random nature when different frequency measurement points are selected. For the above problems, a method is proposed to select the frequency measurement point based on the centre… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
