Abstract: Provided are a control method for a home energy system (100), an energy system, an energy management device, and a computer-readable storage medium. The control method includes: when the home energy system (100) is in a grid-connected state and a non-time-shifting power generation device is in a power-supply state, obtaining net power of the home energy system (100) during each power consumption time period of a current day, and when the net power is smaller than zero, controlling, based on an electricity price of the public grid (20), the home energy system (100) to be power by an energy storage device (12) or by the public grid (20); and when the net power is greater than zero, controlling the power generation device to output electric energy to the energy storage device (12) or the public power grid (20).

Abstract: The present disclosure provides a power management method, a power management device (10), an energy management device (70), an energy system (100), and a storage medium (300). The power management method includes: obtaining first generated power of the first power generation device (30) and consumed power of the one or more loads (200); controlling, when the first generated power is greater than the consumed power, the energy storage device (50) to store power; and outputting, based on a determined electricity selling period, electric quantity of the energy storage device (50) to a power grid (400) during the electricity selling period.
