Abstract: An anti-theft device of an operational vehicle, in which an operation of cancelling an anti-theft mode is simply and easily performed, is provided. The anti-theft device includes: a travel regulation unit (70) which maintains, when the anti-theft mode is set, the operational vehicle (1) in a state where the operational vehicle (1) cannot travel; and a wireless operation terminal (80) which wirelessly operates an operational device (20). When the wireless operation terminal (80) communicates with a controller (70), the wireless operation terminal (80) performs identification authentication, and when the identification authentication between the wireless operation terminal (80) and the controller (70) is successfully performed, the travel regulation unit (70) cancels the anti-theft mode. Since the wireless operation terminal (80) is only made to communicate with the controller (70), and thus the anti-theft mode is cancelled, the operation of cancelling the anti-theft mode is simply and easily performed.

Abstract: A solar power generation system includes a storage battery, a solar power generation device that is provided on the side of the storage battery and outputs solar generated power, and a power control device. The power control device includes a variation component extraction unit that extracts a shade variation component from a generated power signal measured by the solar power generation device, and a smoothing unit that smoothens the shade variation component obtained by the variation component extraction unit. The power control device obtains a charge/discharge target value of the storage battery on the basis of an output signal from the smoothing unit.
