Title:
POWER GENERATION SYSTEM, POWER GENERATION CONTROL DEVICE, POWER GENERATION CONTROL METHOD, AND METHOD FOR INCREASING INTERCONNECTED POWER GENERATION OF POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/003947
Kind Code:
A1
Abstract:
A second power generation facility is newly added to an already connected first power generation facility, and combined electric power generated by the facilities is controlled by controlling electric power to be generated by the second power generation facility in accordance with an upper limit value which is defined by a system interconnection capacity of the already connected first power generation facility, or in accordance with a target value which is arbitrarily defined with consideration of the system interconnection capacity. The power generation system is characterized by comprising: a first power generation facility for generating electric power using a first energy source; a second power generation facility for generating electric power using a second energy source; a second power generation control device for controlling the electric power to be generated by the second power generation facility; and a power generation control device for supplying combined electric power, that is, the total of the electric power generated by the first power generation facility and the electric power generated by the second power generation facility, to a power grid, said power generation control device having a generated-power prediction means for predicting electric power to be generated by the first power generation facility, whereby the system calculates a limit command value of the electric power to be generated by the second power generation facility on the basis of an electric power value which is obtained by subtracting a predictive value obtained by the generated-power prediction means regarding the predicted electric power to be generated by the first power generation facility from the upper limit value set based on the system interconnection capacity or from the target value arbitrarily defined with consideration of the system interconnection capacity, determines whether or not combined electric power, that is, the total of the predictive value of the electric power to be generated by the first power generation facility and the calculated limit command value of the electric power to be generated by the second power generation facility, exceeds the upper limit value or the target value, and transmits the calculated limit command value as an output control signal to the second power generation control device or to the second power generation facility when the upper limit value or the target value is exceeded.
