This paper presents results from case studies of the future power systems in Morocco and Egypt, with a high increase in renewable generation capacity. Datasets representing 2030 scenarios have been generated and studied with a simplified grid-market model that takes into account variable renewable generation, energy storage and electricity grid constraints. Simulation results for Morocco and Egypt are studied and compared, with emphasis on the benefit of energy storage.
Wide-area frequency/voltage measurements are used to observe and record changes in power system operating conditions. This study introduces an application of the frequency/voltage (F/V) wide-area measurements for identifying the generator trips. These measurements are received from the frequency disturbance recorders (FDRs). The FDRs transmit their measurements over the transmission control protocol/internet protocol-based communication network to the data concentrator server (DCS) hosted at Helwan University. The transmitted data from FDRs to the DCS using IP protocol cannot guarantee the quality of service while it provides the best effort delivery for data packets. Missed data at the DCS are expected as a result of number of factors including packet drop because of network congestion, buffer overflow at the source or destination, corrupted packets rejected in-transit or faulty networking hardware. The study introduces a new technique to compensate the missed data using principal component analysis in order to determine a specific signature and properties for each generator trip in the power system network. These signatures are compared with recorded signatures using minimum distance classification to determine a probable match. The real-time measurements collected at DCS showed that some data are missed because of the previously mentioned factors.
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.
