1. A power system adjusting device including: a renewable energy power generation device configured to generate power using renewable energy; a power generation device having a first responsiveness and being capable of adjusting power to be output and/or a demand device capable of adjusting power to be consumed; an energy storage device configured to have a second responsiveness equivalent to the first responsiveness or equal to or greater than the first responsiveness, store received power, and output stored power; and a power consumer including equipment that consumes power output from the renewable energy power generation device, power output from the power generation device, and power output from the energy storage device, the power system adjusting device comprising:
a target presentation unit configured to indicate target power;
a power acquisition unit configured to obtain combined power obtained by adding power output from the renewable energy power generation device and power output from the power generation device and/or power consumed by the demand device, power output or consumed by the energy storage device, and power consumed by the power consumer; and
a command value generation unit configured to generate a first command value and a second command value such that the combined power asymptotically approaches the target power, wherein
the combined power includes a long- and intermediate-period component including a first variation component and a short-period component including a second variation component belonging to a frequency band higher than the first variation component, and
the command value generation unit is configured to:
output the first command value corresponding to the long- and intermediate-period component to the power generation device and/or the demand device; and
output the second command value corresponding to the short-period component to the energy storage device.
