Optimal Configuration Method of Hybrid Storage System Tracking the Wind Power Plan

The integration of wind power with variability brings a series of problems to the dispatching of power grid. To solve this problem, this paper proposes an optimal configuration method of hybrid energy storage tracking wind power planning. First, the fluctuation between planned and actual wind power output, as well as the battery energy storage regulation demand is introduced. Then, the power distribution methods of lithium batteries and super-capacitors in hybrid energy storage are studied. Finally, considering the energy storage operating constraints, the optimal configuration model of hybrid energy storage tracking wind power plan is established. Case study results show that the proposed method can reduce the cost and the deviation between reported and actual output of wind power by hybrid configuration of two types of energy storage batteries.
