Control and management method for household electric energy storage system

The invention discloses a control and management method for a household electric energy storage system. The method aims at a user which is provided with a distributed renewable energy power generation device (such as a photovoltaic power generation panel, a small-sized wind power generator and the like) and a household electric energy storage system (such as Power Wall of Tesla) and carries out time-of-use electricity price, and according to the current power generation amount, power consumption and electricity price, optimizes a charging and discharging strategy of the electric energy storage system. For example, when the power generation amount is excessive, the redundant electric energy is stored; when the power generation amount is insufficient or the electricity price is high, the stored electric energy is used. According to the method, the power generation cost of distributed renewable energy sources, the time-of-use electricity price, the storage cost of electric energy and the loss of charging and dis
