    Abstract: Disclosed are an apparatus and a method for controlling voltage in a combined generation system. A voltage control apparatus according to the present invention comprises: a wind power generator and a diesel generator for generating power to be supplied to systems or loads; an energy storage for storing the power generated by the wind power generator or the diesel generator; and a controller which stores the reactive power, generated in the diesel generator, in the energy storage by controlling the reactive power of the diesel generator according to the output state of the wind power generator, and performs a control operation so that the reactive power, stored in the energy storage, can be supplied to the systems or the loads when voltage measured at a connection point between the systems and the loads is lower than tolerance. According to the present invention, by performing the voltage control at the system connection point by using the reactive power of the diesel generator in the combined generation system of the wind power and diesel generators, a stable system operation can be possible.

    Abstract: PURPOSE: A wind power density prediction method is provided to reduce costs by constructing a geo-statistical model for onshore wind power density analyses by utilizing meteorological reanalysis data and various topographical data. CONSTITUTION: At least one independent variable is inputted into an operation processing unit(S10). The operation processing unit receives dependent variable input and independent variable input, and performs a stepwise regression analysis method(S20). The operation processing unit performs variable standardization to solve the unit difference between the dependent variable and the independent variable(S21). The operation processing unit determines the regularity of each dependent variable and independent variable(S22). The operation processing unit estimates a multiple regression equation having the biggest R-square value by using regression coefficients(S30).
