Distributed energy systems with solar photovoltaic (PV) power grow rapidly in recent years in China. Accurate power forecasting is important for deep utilization and new exploitation of PV power. This study advances power forecasting modelling of PV systems using a method based on similar day selection and M5' model trees. A one-day-ahead power output forecast model is derived for an experimental...
The output power of photovoltaic (PV) power generation system is related to solar irradiance, temperature, humidity and other meteorological conditions. The output powers in the similar days, which are much alike in meteorological conditions and social activities, will be more likely close. In this paper, a prediction algorithm combining the time series and similar day is proposed to predict the power...
In this paper, the four-point bending beam fatigue test control system was modified after analyzing the factors affecting the accuracy of test results. Subsequently, a fractional factorial experimental design method named “uniform design” was applied on the development of laboratory asphalt mixture fatigue prediction model. The regression models expressing the relationships between the influence factors...
Effective incident management and traffic control measurements require a full understanding of the characteristics of incidents to accurately estimate incident durations and to help make more efficient decisions to reduce the impacts of non recurring congestion due to these accidents. The Incident duration includes four parts: detection time, response time, clearance time and recovery time. Many of...
