<p>The present invention relates to a control apparatus and a control method which are capable of reliably preventing electric power not required to be returned to an electric power system from flowing out to the electric power system. A bidirectional DCAC converting unit 33 converts DC power stored in a storage battery 15 to AC power, and outputs the converted power to each load. Further, a current detecting unit 34 is arranged on a wire from the electric power system which is connected to a wire between the bidirectional DCAC converting unit 33 and each load, and the current detecting unit 34 detects a current flowing between the connection point and the electric power system. A control unit 36 increases/reduces an amount of AC power output of the bidirectional DCAC converting unit 33 based on an amount of current detected by the current detecting unit 34, thereby to control a supply of electric power to each load. The present invention is, for example, applicable to a power conditioner of a home electric power system provided with a photovoltaic panel.</p> |
