    Kyoto Protocol has helped Japanese electric utility industry to establish its own Greenhouse Gas (GHG) emission reduction target. However, Kyoto Protocol does not specify the allocation of the GHG emission reduction target to each power company in the industry. In this research, it began with the analysis of the Japanese power system structure and its generation performance on GHG emission. Based on these analyses, allocated the target emission allowance to each General Electric Utilities (GEUs) in Japan under the Kyoto Protocol period based on two allocation approaches, namely Grandfathering Approach and Benchmark Rule Approach. Under the Grandfathering Approach, Chuden; Chugoku and Rikuden are on track to the allocation cap under the Kyoto Protocol. However, this is not the case when Benchmarking Approach is used for calculation. Chuden and Chugoku would be required to take significant reduction exercise now in order to keep their emission level within the allocation cap under both Grandfathering and Benchmarking Rule Approach. 311 Earthquake in northeast coast of Japan has resulted in a massive destruction of nuclear power station. Consequently, more thermal power is expected to fill out the nuclear lost. Therefore, the emission generated from electricity generation is expected to increase significantly. According to the calculation, if Japanese electric utility industry would like to achieve its emission reduction target under Kyoto Protocol even after taking the 311 Earthquake into consideration, it would need to further reduce an average of 122.1 million metric tons of GHG emission in the final two year of the Kyoto Protocol period.

    The off-shore wind energy has been drawing interest recently. This research is focusing on the potential analysis of off-shore wind energy surrounding entire Japan coast using GIS technology. Base on the economy and environment assessment, this research is evaluating the current situation and forecasting on future of wind energy technology in Japan. In order to reduce the green-house gas emission, renewable energy (such as wind energy, solar energy, fuel cell...) will gradually substitute can be installed the primary energy resource (such as coal, oil, scale gas..). Based on GIS technique, wind power turbines in the surrounding area of Japanese coast-line. In the study, 2000kW rated wind turbines are considered for further installation. As the result of this study, we have determined that 108,067 in 330 places number of off-shore with annual generation of 180.0TWh are expected. This is equal to 20% of annual total generated power of Japan in 2011. In this study, after determination of potential evaluation of offshore wind power for the entire Japan, we have applied a well-know Dynamic Programming (DP) method to propose a plan of installation of the above determined number of offshore wind power units from year 2012 to 2030 respectively. As far as we know, there is no such scheduling for introducing offshore wind power in Japan. View full abstract»

    This paper aimed to introduce a real-time reactive power controller based on artificial neural network. A feed-forward employing back-propagation was used as training algorithm. The inputs to the ANN were real and reactive power of each load, and the targets were to switch ON/OFF the capacitors during normal and abnormal conditions. The network was trained using Matlab and the weights corresponded to minimum (MSE) error were fed to the microcontroller unit. This method was tested in a radial distribution system model and implemented using Zilog Microcontroller. The results were monitored using web-based power monitoring. The method was validated and results were satisfactorily obtained. View full abstract»

    Design of the robust finite time functional observer in uncertain linear systems is studied. Its aim is to design a robust functional observer which can estimate the state linear functions of uncertain linear systems in a predefined finite time. Based on the parametric solutions for a class of Sylvester matrix equations, this paper presents the parametric expressions of all the gain matrices for the finite time functional observers in the linear systems without uncertainties, in which the free parameters can offer all the design degrees of freedom needed in the robust finite time functional observer design. By using the offered degrees of freedom, the robust indexes are parameterized and the design problem of the robust finite time functional observers is changed into a minimization problem and an algorithm to design the robust finite time functional observers for the uncertain linear systems is proposed. Finally, a numerical example and its simulation results show the simplicity and effectiveness of the proposed design method of the robust finite time functional observers in the uncertain linear systems.

    This paper discusses a design method of self-tuning control. In order to control a nonlinear system by using the linear control theory, a controlled plant assumed to be locally linear. Because the dynamic characteristics of an approximated linear model vary widely in response to operating environment, a plant model must be modified according to the changed environment. To obtain an accurate model, a lot of linear models are simultaneously identified, and a control system is designed based on one local linear model. To decide one local linear model from many linear models at sampling interval, the plant parameters of local linear model candidates are estimated using GPGPU (General-Purpose computing on Graphics Processing Units).

    Actuators in control systems have several limitations in mechanically and electrically, and these limitations cause instability and degradation of a controlled performance. In this study, we treat an anti-windup problem of tracking controller for nonlinear 2-link manipulator using a nonlinear model predictive control (NMPC). Proposed method is designed with focusing to a relationship between maximum values of control inputs and a time-constant of a reference trajectory, which is one of tuning parameters of NMPC. In order to achieve a tracking control of a 2-link manipulator with keeping the control input under a limitation of it, the time constant of a reference trajectory in proposed new NMPC is tuned based on limitation of control inputs. At first, we analyze the relationship between time constant of the reference trajectory and the maximum values of the control input by numerical simulations using MATLAB/Simulink. And next, an algorithm to tune the time-constant of the reference trajectory according to input limitation is designed based on analysis results. In order to show an effectiveness of proposed anti-windup compensator, numerical simulations of tracking control of the two-link nonlinear manipulator with input limitations are performed.

    In this paper, we discuss a parameter-tuning method for an Adaptive Nonlinear Model Predictive Controller(ANMPC). As a control problem of using the nonlinear model predictive control (NMPC), our group has already proposed tracking controller for a nonlinear two-link planar manipulator having two actuators using the Adaptive Nonlinear Model Predictive Controller. This ANMPC uses a time-variant coefficient instead of a time constant of the reference trajectory which is an ideal trajectory to converge on a desired value. New reference trajectory has some control parameters about the reference trajectory and user of ANMPC must tune these parameters based on controlled system's properties. For this problem, new parameter-tuning method for ANMPC is proposed by quantitatively analizing a relationships of between system's behavior and parameters of ANMPC. In order to show an effectiveness of proposed parameter tuning method, numerical simulations of tracking control of the two-link nonlinear manipulator with several conditions are performed.
