Capacity Allocation of Wind Farm Energy Storage System Considering Economic Function

Abstract

The energy storage system with the ability of bidirectional absorption and release of power, realizes the temporal and spatial transfer of power and provides the key technical support for the safe and friendly integration of wind power into the grid. In practical engineering, the high cost restricts the large-scale application of energy storage. Therefore, when selecting the capacity configuration scheme, the introduction of economic evaluation under the premise of meeting the functional applicability can accelerate the industrialization of energy storage. Combined with the capacity configuration of economic and functional energy storage, this paper integrated three typical evaluation criteria for the economic evaluation of energy storage system, summarized three methods of capacity configuration, and analyzed the advantages and disadvantages of the three methods by comparison. Moreover, the basic process of capacity allocation of energy storage system was given. Finally, the existing problems and future research directions of energy storage configuration were pointed out.
