Problems solved by technology

[0003] Incidentally, the control section may select the power storage device as a possible choice of the power source of the heat pump device during a power outage of the commercial power supply, and in this case, since the heat pump device has a higher rated power consumption than general household appliances , which may inadvertently reduce the amount of power stored in the power storage device

Embodiment Construction

[0016] (1 Overview

[0017] like figure 1 As shown, the load control system 1 of this embodiment is used to control the loads 7 used in the facility 100 (including at least the first load 71 in this embodiment). The load control system 1 is used by being installed in facilities 100 such as residents of individual houses and collective houses, and the like. Note that the facility 100 in which the load control system 1 is installed is not limited to each resident of a detached house or a collective house. The load control system 1 may be installed in a non-residential building such as a factory, commercial building, office building, hospital or school.

[0018] like figure 1 As shown, the load control system 1 of the present embodiment includes a controller 11 configured to control a load (first load 71). The load (first load 71 ) operates with electric power supplied from at least one of the power converter 3 and the system power supply 2 . The power converter 3 is configu...

Abstract

An object of the invention is to reduce power consumption or power consumption of a load during operation of a power converter in an autonomous operating state. The load control system (1) comprises a controller (11) configured to control a load. The load is configured to operate with power supplied from at least one of a power converter (3) and a system power supply (2), the power converter (3) being configured to convert direct current power supplied from a distributed power supply (5) into alternating current power. The controller (11) is configured, upon detecting that the power converter (3) is operating in the autonomous operating state, to control an operating mode of the load such that the load operates in a second operating mode in which the power consumption of the load is lower or lower than in the first operating mode, and to control the operating mode of the load in a second operating mode in which the power consumption of the load is lower than in the first operating mode. In the first operation mode, the load operates with alternating current power supplied from a system power supply (2).

Description

technical field [0001] The invention relates to a load control system, a power conversion system, a distributed power supply system, a load control method and a program. In particular, the present invention relates to a load control system, a power conversion system, a distributed power supply system, a load control method, and a program configured to control a load that operates with power supplied from at least one of a system power supply and a distributed power supply. Background technique [0002] Patent Document 1 discloses a hot water supply system including: a heat pump device for heating water in a hot water storage tank; and a combustion type heating device for heating hot water supply water. The hot water supply system also includes a power conditioner (power converter) and control components. The power conditioner switches the power supply of the heat pump device (load) to one of commercial power supply (system power supply), photovoltaic generator and power sto...
