Title:
マイクログリッドにおける電力の需給調整を行う制御装置
Document Type and Number:
Japanese Patent JP4749375
Kind Code:
B2
Abstract:

To keep the demand and supply balance of power and the phase balance of a load in a microgrid.

A microgrid power supply system 1 is a small-scale power supply net which enables the regional self supply of power by combining a plurality of distributed power sources and a power storage system in a demand area, and controlling the electric power generation of the distributed power sources, according to the situation of demand and supply. A high-order power system 2 is a supply net of power that is sent to consumers via a transmission line, a substation, and a distribution line from a large-scale power plant as usual. In case that it can not supply power by itself within the microgrid power system 1, it will receive the supply of power from the high-order power system 2. A water heater 3 for adjustment is a load for consuming power or suppressing the consumption of power so as to adjust the power in the microgrid power system 1. A controller 4 acquires system information concerned with the microgrid power system 1, and calculates the power value to be adjusted based on the system information, and sends the power value to the water heater 3 for adjustment, etc., so as to adjust the power.
