Abstract

Smart Grid is a large complex system, involving generation, transmission, distribution and delivery of four links. This paper analyzes the structure of the smart grid system in depth with a combination of qualitative and quantitative research approach. Then it explains state variables, rate variables and constants in the development of smart grid system under the Vensim software environment and analyzes subsystems causal feedback relationship in a macro point of view. Finally, this paper analyzes the simulation on the amount of funding and professionals in the smart grid system dynamics flow diagram after inputting DYNAMO language equations. The simulation analysis shows that the development of the smart grid should focus on training professionals. Professional talent is a source of strength in the smart grid development. At the same time, we should also pay attention to industrial policy related to the smart grid and seek break under the guidance of policy. http://dx.doi.org/10.11591/telkomnika.v12i12.5986

Abstract

Rural energy is the cornerstone of the development of economy, as a major agricultural province, the scientific prediction on rural energy consumption is particularly important in Hebei Province. In this paper, the GM(1,1) model of the grey theory was used to predict the rural energy consumption as well as the proportion of total energy consumption ratio of Hebei Province, in 2015 the rural energy consumption would reach 833.18 million tons of standard coal, the total energy consumption ratio would reach 28.39%, and the relative error and posterior test are all qualified. Finally, It can provide a scientific basis for the development of energy strategy planning of Hebei Province, and put forward policy recommendations. DOI : http://dx.doi.org/10.11591/telkomnika.v12i3.4516
