Optimal Allocation method on Distributed Energy Storage System in Active Distribution Network

With distributed generations (DG) including the wind and photovoltaic power generations continually connected to the distribution network, reasonable allocation of energy storage system is extremely important to active distribution network (ADN). In this paper, a method to optimize the location and capacity of the embedded distributed energy storage system (DESS) is proposed to meet the needs of ADN and DGs. Firstly, the model of DGs is built according to the natural characteristics of wind and solar energy. Secondly, the model of allocating the DESS is established to achieve the best economical investment results with the constraints of ADN, DG and DESS themselves. Finally, a test ADN with wind and photovoltaic power generations is used to verify the efficiency of the method proposed in this paper.
