【Abstract】 Large-scale stochastic disordered access of the distributed battery brings a new challenge to the traditional micro-grid power dispatching system. In order to remove impact of disordered charging upon the micro-grid, a micro-grid power dispatching model taking into account charge/discharge management of the distributed battery was established, and it could consider the loss cost of intelligent discharging of the distributed battery. Under the precondition that travel requirements of distributed battery users were satisfied, the charge/discharge strategy of the distributed battery as well as the output of power generating units of the micro-grid were optimized, so that optimal comprehensive cost was obtained for the power dispatching strategy. Finally, taking an existing micro-grid in Southern China as example, the effectiveness and feasibility of the proposed intelligent charge/discharge management strategy for the distributed battery was verified.更多还原
