Renewable energy sources (RESs) are the replacement of fast depleting, environment polluting, costly, and unsustainable fossil fuels. RESs themselves have various issues such as variable supply towards the load during different periods, and mostly they are available at distant locations from load centers. This paper inspects forecasting techniques, employed to predict the RESs availability during different periods and considers the dispatch mechanisms for the supply, extracted from these resources. Firstly, we analyze the application of stochastic distributions especially the Weibull distribution (WD), for forecasting both wind and PV power potential, with and without incorporating neural networks (NN). Secondly, a review of the optimal economic dispatch (OED) of RES using particle swarm optimization (PSO) is presented. The reviewed techniques will be of great significance for system operators that require to gauge and pre-plan flexibility competence for their power systems to ensure practical and economical operation under high penetration of RESs.
Cyberspace reaches all corners of human access and includes cyber-physical systems such as power grids, communication networks, industrial plants, transportation networks, ports and shipping, and a myriad of networked home appliances through the Internet of Things.
One goal of this article is to engage and inform personnel in the maritime domain to help secure cyberspace from adversaries. Another goal is to provide an introductory systems view to help manage cyberspace security. We show that cyberspace is a reflection of human networks and share the
advantages and flaws inherent in these human networks. Trust in this network is the missing link that prevents us from securing this network. Although this viewpoint is not an exact model, we believe it helps simplify the complexity of cyberspace and the wide variety of attacks that are possible.
These goals help the average person see the big picture, and the entire system can become more robust by allowing everyone to participate intelligently in this endeavor. This article explains in a more simplistic but useful manner the domain of cyberspace, enabling better security of the ecosystem.
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.
