PROBLEM TO BE SOLVED: To solve a problem that, in such a power control device that determines a charge and discharge schedule on the basis of prediction, balance between the demand and the supply collapses in a case the prediction fails.SOLUTION: A heat pump 22, a wiring line L2 for transmitting a charging power Pv to a commercial vehicle 28, and a load 44, are demand-side means in a system 10. On the other hand, a solar panel 20, and a wiring line L1 for transmitting a power Psys of a system power supply 26 are supply-side means in the system 10. A power requested by the demand-side means is supplied by the supply-side means. This is achieved by a demand-supply balance adjustment part 30. In this case, a scheduler 50 retrieves a charge and discharge power of a battery 24, that is appropriate for making the cost in the system 10 be at the minimum, on the basis of prediction processing. On the basis of this, a charging-side upper limit guard value Icmax and a discharge-side upper limit guard value Idmax for the battery 24 are outputted to the demand-supply balance adjustment part 30. |
