Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings forming a part of this specification. In all the drawings, the same symbols are attached to the same or similar parts, and their repeated descriptions are omitted.

[0022] figure 1 It is a system configuration diagram showing the power supply system of this embodiment. Commercial power (for example, 100V / 200V single-phase alternating current) is supplied from a power system AC of a power company to power consumers through a power line Lp. Here, among the power consumers, the power consumers on the electricity selling side with distributed power sources PV are called first power consumers A1, A2, ..., and the power consumers on the power purchasing side without distributed power sources PV are called Second electricity consumers B1, B2, . . .

[0023] Here, when referring to each of the first power consumers A1, A2, ..., it is described as t...

Abstract

Disclosed is an electric power supply system containing: a distributed power supply which is disposed in at least one part of a first electric power consumer unit; a power line which supplies the surplus electric power generated in the distributed power supply to at least one part of a second electric power consumer unit; and a management device which manages the trade price of the surplus electric power supplied via the power line. The management device determines the trade price of the surplus electric power for subsequent days on the basis of a prediction value for the amount of surplus electric power in the first electric power consumer unit and a prediction value for the amount of electric power consumption in the second electric power consumer unit over the subsequent days.

Description

technical field [0001] The present invention relates to an electric power supply system for electric power supply between a power consumer having a distributed power source and a power consumer not having a distributed power source. Background technique [0002] As a conventional power supply system, there is a power supply system described in Patent Document 1. In this conventional example, a first power consumer group having a distributed power source such as a solar power generation system and a second power consumer group not having a distributed power source are connected to a common power system, and the power generated by the distributed power source of the first power consumer is connected to a common power system. The surplus electric power of the first electric power consumer is supplied to the second electric power consumer via the common electric power system, and the balance of the electric power supply of the first electric power consumer and the second electri...
