Island type micro-power-grid energy storage control method based on consistency algorithm

The invention provides an island type micro-power-grid energy storage control method based on a consistency algorithm. The method includes the steps: detecting the charge state of a super capacitor and the power the super capacitor is output to a micro-power-grid; determining whether the charge state of the super capacitor reaches a limit value, and triggering a state limit outer ring to make the micro-power-grid run in a state limit mode if the charge state of the super capacitor reaches the limit value, otherwise, the micro-power-grid runs in a normal mode; calculating the total reference output power of a storage battery through a self-adaptive control inner ring on the basis of the actual reference output of the super capacitor in different running modes; sharing the total rated power of a storage battery in the micro-power-grid and the total reference output power of the storage battery through the consistency algorithm; and through the shared information, guiding the output power by the storage batteries according to the proportion of the rated power of each battery member to the total rated power of the storage battery. Distributed control over the micro-power-grid can be achieved. Meanwhile, the control method helps to solve the problem that a conventional hybrid energy storage control strategy cannot effectively handle a situation that the electric quantity stored by an energy storage element is too high or too low.
