The invention discloses a control method and device for improving the consumption of a
distributed power source. The method comprises the following steps: S1: acquiring power generation power within acurrent time period,
power consumption power within the
current time period and a current charge state; S2, calculating non-consumption power within the
current time period; S3, judging whether the non-consumption power within the
current time period is greater than zero, and if not, executing step S4; S4, judging whether the current charge state is greater than or equal to the minimum charge state, and if so, executing step S5; S5, performing accumulation to obtain a non-consumption power sum, and performing accumulation to obtain total
charge and discharge power; S6, calculating the difference between the non-consumption power sum and the total
charge and discharge power to obtain a
power difference; and S7, selecting the minimum power of the maximum
discharge power and the
power difference of a local
energy storage system, and sending a command to
discharge at the minimum power to the local
energy storage system. By adoption of the control method and device disclosed by the invention, the consumption of the
distributed power source can be maximized on the entire time period, and meanwhile the stability of the
switching power between the
distributed power source and a grid sideis maintained as much as possible.
