A high-voltage direct-current (HVDC) grid protection strategy to suppress dc fault currents and prevent overcurrent in the arms of modular multilevel converters (MMCs) is proposed this paper. The based on coordination half-bridge MMCs hybrid circuit breakers (DCCBs). This achieved by allowing MMC submodules be temporarily bypassed prior opening DCCBs. Once isolated DCCBs, will restore normal operation. performance method assessed compared when are blocked no corrective action taken. To...
To protect HVdc grids from dc faults, the concept of a hybrid circuit breaker is widely accepted due to its low conduction losses and fast interruption speed. For well-built grid, massive number breakers have be installed. This will lead high capital costs. An interlink based on an idea sharing main branch between two proposed reduce overall costs in grid. Compared existing breakers, can achieve same fault capability with fewer components. Novel structures branches are designed their...
This study analyzed the effects of ecological factors on secondary metabolites Scutellaria baicalensis using two sources: 92 individual roots S. from all over China, and metabolites, medicinal materials inorganic element contents obtained testing rhizosphere soil samples. The used environmental data Genuine Medicinal Material Spatial Analysis Database. Most chemical constituents were negatively correlated to latitude positively temperature; generally, 21 higher at low latitudes than that...
The wide utilization of gas-fired generation and the rapid development power-to-gas technologies have led to intensified integration electricity gas systems. random failures components in either or system may a considerable impact on reliabilities both Therefore, it is necessary evaluate systems considering their integration. In this paper, novel reliability evaluation method for integrated electricity–gas (IEGSs) proposed. First, network equivalents are utilized represent models generating...
DC technologies will be essential building blocks for future distribution networks.As in any system, these networks face crucial threats imposed by short-circuit faults.Protection is thus of great interest, and it likely rely on circuit breakers (DCCBs).Among available configurations, Z-source solid-state (Z-SSCBs) are promising candidates protecting low medium-voltage networks, as well equipment due to their structural control simplicity cost.In this paper, start-ofthe-art Z-SSCBs...
There has been widespread use of causal inference methods for the rigorous analysis observational studies and to identify policy evaluations. In this article, we consider coarsened exact matching, developed in Iacus et al. (2011). While they some statistical properties, study approach using asymptotics based on a superpopulation inferential framework. This methodology is generalized what termed as confounding, which propose two new algorithms. We develop asymptotic results average effect...
