Installed wind power capacity keeps rapid increase, but wind power curtailment is becoming increasingly serious. Demand response is a good choice to promote the integration of wind power. This paper builds a two-stage unit commitment model incorporating demand response with the aim of promoting wind energy utilization. Firstly, a price determination model is proposed to find the optimal time-of-use...
In recent years, the number of EVs keeps a rapid growth and the increasing charging load brings new challenges to the operation and control of the power system. Meanwhile, the application of energy storage system is drawing the attention in both academia and industry. Both of the above elements play important roles in the Energy Internet. This paper aims to find a balance status between the power...
The short-term load forecasting error highly affects the security and economic operation of power systems. The load in different areas are distinct in the composition of consumers, impact factors, and profiles, and are thus of different forecast ability. Understanding the correlations of load forecast error among different areas would provide significant insight on the ways of managing the forecast...
Dispatch flexibility denotes the capability of electrical generation that can be dispatched to serve the load. Hydro power generation with water reservoir has favorable dispatch flexibility that can be used to mitigate the intermittency and uncertainty of photovoltaic. Hydropower and photovoltaic can be coordinated by storing water energy in the peak hours of solar and shifting it to off-peak periods...
The fluctuations and forecasting errors of wind power require large amount of flexibility in power system operation. The flexibility is often provided by conventional thermal generating units. This paper focuses on the variations in operating cost caused by integration of an increasing amount of wind power in thermal generation system. A new chronological production simulation platform utilized for...
Chang detection is one of the most important research issues in the field of video processing. This paper presents an adaptive method of objects and shadows detection in video streams based on the HSI color space. Bi-models of background is set up via the minimum, the maximum and the largest interframe absolute difference of per static pixel, which are adaptively updated by synthesizing pixel level,...
