Abstract The invention proposes an energy storage economic operation control method and device for a microgrid, and the method comprises the steps: firstly determining an effective state of the electric quantity of an energy storage unit, calculating the charging and discharging power of the energy storage unit, determining a stage index function, determining the optimal operation cost of the energy storage unit, and determining the optimal scheduling strategy of the charging and discharging power of the energy storage unit, thereby achieving the intelligent scheduling of the energy storage unit in the microgrid and guaranteeing the economic and stable operation of the energy storage unit. According to the technical scheme of the invention, the method achieves the search towards the center from two directions (sequential and inverted sequences) based on a bidirectional dynamical planning algorithm, and greatly reduces the calculation burden of the dynamical planning algorithm. Moreover, when the requirements for the c
