High uncertainties in day-ahead unit commitment (UC) introduced by the deviation of wind power forecast error require high amount of spinning reserve, which counteracts the cost and fossil energy saving contributed by wind power integration. To mitigate the above problem, a two-level unit commitment coordinated strategy (TLUCCS) is presented based on the characteristic of wind power forecast accuracy...
In the paper, a novel adjustable reactor is proposed. In the novel reactor, a transformer with air gap is chosen and its primary winding is connected in series or parallel to the power system, the primary winding voltage is detected and passed to a phase shift circuit. The output signal of the phase shift circuit functions as the reference signal. A voltage-source inverter (VSI) is applied to produce...
In this talk, some efficient methods for the electromagnetic (EM) simulation of periodic structures are reviewed, including the Method of Lines (MoL) and the Finite Difference Frequency Domain (FDFD) method for the propagation characteristic simulation of substrate integrated waveguide (SIW), and the Partial Basic Solution Vector (PBSV) based Domain Decomposition Method (DDM) for the scattering and...
A parametric design problem of the unknown input observers in the linear time-invariant systems is investigated. The aim is to design the parametric expression of the state observers that can estimate the state of the linear time-invariant systems with the unknown input disturbances. Based on the parametric solutions of a Sylvester matrix equation, the parametric expressions of all the gain matrices...
This paper introduces an expert interpretation-based Markov chain geostatistical (MCG) framework for classifying land-use/land-cover (LULC) classes from remotely sensed imagery. The framework uses the MCG method to classify uninformed pixels based on the informed pixels and quantify the associated uncertainty. The method consists of the following steps: 1) decide the number of LULC classes and define...
Co-integration theory was applied in this paper to verify the function of highway industry in Henan economic development. It shows that there is a long-term stable relationship between highway industry investment in Henan and Henan economic development. The construction of highway in Henan started rather late and its positive impacts on Henan economic development are inconspicuous, however, economic...
The cellular neural/nonlinear network (CNN) has become a useful tool for image and signal processing, robotic and biological visions, and higher brain functions. visual illusion is defined as any fallacious perception of reality. In 1997, Chua proposed a CNN template named face-vase illusion (FVI) CNN. It can simulate some visual illusions. In this paper, we figure out the local rules of the FVI CNN...
Based on the anti-HBV infection therapy clinical data of the Peginterferon Alfa-2a plus placebo for HBeAg-Positive chronic hepatitis B patients, this paper establishes a mathematical model consisting of three differential equation systems and aims to describe and understand the dynamics of host cells, viruses, the immune system, as well as predict the long term curative effects. The results of numerical...
Based on the clinical data of the lamivudine for HBeAg-positive chronic hepatitis B patients and the HBV infection dynamic model proposed by Nowak et al., this paper sets up a mathematical model consisting of two differential equation systems that enable us to describe and understand the dynamics of host cells, viruses and the immune system. Our model provides a possible interpretation for the curative...
