Power supply system, power supply method, program, recording medium, and power supply controller

Abstract

Provided is a power supply system etc. which can stabilize and supply power to a load while a power generation source which generates an unpredictable amount of power is used as a power generation means that is electrically connected to a commercial system. The power generation source is employed in a manner similar to a power generation source which uses natural energy such as sunlight or wind power for example. A first power generation source, which generates an unpredictable amount of power, is provided together with a storage means and a second power generation source, which is able to vary the power supplied, as a distributed power source unit. When the power supply value of the first power generation source is less than a standard power value, which is the power value that should be output by the distributed power source unit, the power storage means and the second power generation source supply the shortage in the power value. When the power of the commercial system stops, the distributed power source unit becomes the standard power source, the use of another independent power source becomes possible, and the stable supply of power is further facilitated.

Description

technical field [0001] The present invention relates to a power supply system, a power supply method, a program, a recording medium, and a power supply control device, and more particularly, to an electric power supply system comprising a commercial power supply source and a distributed power supply unit capable of supplying loads from one or both of the commercial power supply source and the distributed power supply unit. Electric power supply system, etc. Background technique [0002] As a mechanism for supplying electric power to loads such as household loads, a utility interconnection type system in which an independent power source such as a solar cell is electrically connected to the commercial system in addition to the commercial system has been proposed (see Patent Document 1). [0003] On the other hand, the applicant has researched and developed a technology for effectively utilizing electric power obtained by solar power generation or the like by including a power...

AI Technical Summary

Problems solved by technology

[0011] However, power generators that utilize natural energy sources such as solar or wind power cannot predict the amount of power generated

Therefore, it cannot be a stable power supply source

In particular, since it is used as a power supply source during a power outage in a commercial system, it cannot become a continuous and stable power supply source, which has become a serious problem.
