Description

{MANAGEMENT METHOD FOR ELECTRIC CHARGE}

More particularly, the present invention relates to a method of predicting and managing a home electricity rate according to the home renewable energy and energy storage device built in the home, self-supply of home energy and energy trading.

Conventional energy saving technology is a passive type that reduces the consumption of energy supplied from the existing power system. However, in the future, it will solve the domestic energy supply and demand by utilizing the renewable energy and energy storage system connected to the house, It will be possible to actively save energy by collecting energy, operating as a virtual power plant, and generating revenue through energy trading.

On the other hand, the Smart Grid is a power system that optimizes energy efficiency by combining the power grid and information communication technology. It is a technology field that is being promoted in various countries and attracting worldwide attention in recent times. Based on these infrastructures, consumers respond to real-time prices for electricity demand, enabling consumers to actively participate in energy use (DR, Demand Response).

In addition, as renewable energy supply and real-time energy trading are possible at home, it has become possible to reduce electricity bills. However, technologies related to renewable energy, storage, and energy management are under development, but there is no function for energy trading in terms of energy bill settlement.

When the surplus energy is sold to the power system, the measurement value of the existing watt hour meter is lowered by the sales amount, or a counter current watt hour meter for measuring the generation amount of the renewable energy is installed separately. In addition, the home energy management system does not provide charge information according to the energy supply at home in real time.
