Spectral calculation and analysis have very important practical applications in astrophysics. The main portion of spectral calculation is to solve a large number of one-dimensional numerical integrations at each point of a large three-dimensional parameter space. However, existing widely used solutions still remain in process-level parallelism, which is not competent to tackle numerous compute-intensive...
An improved coordinated charging method was proposed to deal with numerous electric vehicles' (EVs') uncertainty charging habits in this work, this method is an optimization model taking EVs' charging start time and charging power as the control variables. In the model users' charging habit was represented by Binomial distribution and the EVs' uncertainty charging demand was imitated by the Mento...
This paper presents a feasibility analysis on a renewable energy dominated power structure in terms of both technological and economic considerations for Hainan Island, China. To determine the optimal system configuration for a hybrid renewable energy system, the software HOMER is used. The assessment criteria include net present cost (NPC), cost of energy (COE), and carbon emission intensity (CEI)...
Multiple voltage stability incidents show that system dynamic components have a great impact on voltage stability. This article mainly analyzes and summarizes the impaction on voltage stability based on the bifurcation theory caused by dynamic characteristics of main components in the power system such as load characteristics, generator characteristics, OLTC and Static Var Compensator (SVC).It Proposes...
