Abstract

In an in-home dispersed power source system designed to supply electric power to a plurality of home electric appliances with using a dispersed power source in combination with a commercial power source, a control means, which is connected to the dispersed power source and the plurality of the home electric appliances via a network and which control means performs ON/OFF control of each of the home electric appliances, is provided, wherein the control means makes each of the home electric appliances follow a response delay of power generation operation of the dispersed power source by selective ON/OFF control of the plurality of the home electric appliances.

Claims

1. An in-home dispersed power source system that is designed to supply electric power to a plurality of home electric appliances with using a dispersed power source in combination with a commercial power source, the system comprising:

a control means that is connected to said dispersed power source and said plurality of the home electric appliances via a network, and that performs ON/OFF control of each of the home electric appliances,

wherein said control means makes each of the home electric appliances follow a response delay of power generation operation of said dispersed power source by selective ON/OFF control of said plurality of the home electric appliances.

2. An in-home dispersed power source system according to claim 1, wherein selective ON/OFF control of said plurality of home electric appliances by said control means is given in accordance with a priority set in each of the home electric appliances in advance.

3. An in-home dispersed power source system according to claim 2, wherein said control means comprises an input means and said priority is configured so as to be changeable by said input means.

4. An in-home dispersed power source system according to claim 2, wherein said control means is configured so as to change said priority by at least one of time and season.

5. An in-home dispersed power source system according to claim 1, wherein said dispersed power source comprises a plurality of power generation means, and wherein an operation number of the power generation means is controlled, depending on power generation electric power demanded for sad dispersed power source.

6. An in-home dispersed power source system according to claim 1, wherein said dispersed power source is configured of a cogeneration facility.

7. An in-home dispersed power source system that is designed to supply electric power to a plurality of hose electric appliances with using a dispersed power source in combination with a commercial power source, the system comprising:

a control means that is connected to said dispersed power source and said plurality of the home electric appliances via a network, and performs ON/OFF control of each of the home electric appliances; and

adjustment means that are respectively provided for said plurality of the home electric appliances,

wherein said control means transmits a delay time of said dispersed power source, which occurs when a load of said dispersed power source is changed, to said adjustment means, and

wherein said adjustment means make each of the home electric appliances follow a response delay of power generation operation of said dispersed power source by performing the ON/OFF control of each of the home electric appliances matching said delay time.

8. An in-home dispersed power source system according to claim 7, wherein said selective ON/OFF control of said plurality of home electric appliances by said control means is given in accordance with a priority set in each of the home electric appliances in advance.

9. An in-home dispersed power source system according to claim 8, wherein said control means comprises an input means and said priority is configured so as to be changeable by said input means.

10. An in-home dispersed power source system according to claim 8, wherein said control means is configured so as to change said priority by at least one of time and season.

11. An in-home dispersed power source system according to claim 7, wherein said dispersed power source comprises a plurality of power generation means, and wherein an operation number of the power generation means is controlled, depending on power generation electric power demanded for said dispersed power source.

12. An in-home dispersed power source system according to claim 7, wherein said dispersed power source is configured of a cogeneration facility.
