The charging behavior of large scale electric vehicle (EV) fleet has the time-spatial characteristics, in this paper the charging characteristics and driving behaviors of an EV was analyzed, and the EV charging load model has been developed. Based on the Monte Carlo method, the charging model of large scale EVs has been built and the impacts of the charging behaviors of the large amount EVs has been...
In a coal-fired power generation system, energy efficiency is increasingly focused on due to the fact that the key indices of power plant such as coal cost and emission are closely related to energy efficiency. However, many coal-fired power plants lack effective energy efficiency program due to: diversified unit equipment type, insufficient or outdated original parameter setting, or diversified operation...
in areas with rapid economic growth, distribution transformer heavy load and overload occur frequently, which may damage the equipment and even lead to power outages. Therefore, it is critical for the utilities to know which distribution transformers are more likely to have the heavy load /overload conditions in the next year in order to facilitate asset management in distribution network. However,...
Extreme weather conditions such as hurricanes, heavy thunderstorms, and severe snow/ice storms could have serious impact to the secure operations of electrical distribution network especially in the city/metropolitan areas and may lead to large scale of power outage to the customers. This paper presents a distribution network outage pre-warning modeling and analytic method under the extreme weather...
