1. A control method for a home energy system, the home energy system comprising a power distribution device connected to a plurality of loads, a non-time-shifting power generation device, and an energy storage device, the control method for the home energy system comprising:
when the home energy system is in a grid-connected state and the non-time-shifting power generation device is in a power-supply state, obtaining consumed electric power of the plurality of loads and generated electric power of the non-time-shifting power generation device during each electricity consumption time period of a current day;
when net power of the home energy system during each electricity consumption time period of the current day is greater than zero, controlling, based on an electricity price of a public power grid during each electricity consumption time period of the current day, the home energy system to be powered by the energy storage device or powered by the public power grid to enable an electricity bill to meet a predetermined condition, the net power of the home energy system during each electricity consumption time period of the current day being a difference between the generated electric power and the consumed electric power; and
when the net power of the home energy system during each electricity consumption time period of the current day is smaller than zero, controlling, based on the electricity price of the public power grid during each electricity consumption time period of the current day, the non-time-shifting power generation device to output electric energy to the energy storage device or the public power grid to enable the electricity bill to meet the predetermined condition.
