摘要
The invention provides a control system of renewable energy power generation equipment which can contribute to a suppression of frequency variation with a period of several minutes to several tens minutes that is a control region of LFC without using auxiliary equipment such as a battery. A control system of renewable energy power generation equipment of the invention includes a measuring unit that measures a frequency of a power grid; a measuring unit that measures meteorological characteristics of the renewable energy power generation equipment; a calculating unit that calculates frequency deviation of the power grid; a calculating unit that calculates an expected power output of the renewable energy power generation equipment and an increase and decrease state value thereof based on the meteorological characteristics measured by the measuring unit that measures meteorological characteristics of the renewable energy power generation equipment; a calculating unit that calculates a correlation coefficient between the frequency deviation of the power grid and the expected power output of the renewable energy power generation equipment; and a determining unit that determines whether or not output adjustment of the renewable energy power generation equipment is necessary by using the correlation coefficient between the frequency deviation and the expected power output, and the increase and decrease state value of the expected power output.
