Abstract
With the continuous complexity of distribution network, and the concepts of active distribution network, smart grid, there may be a number of energy storage systems in distribution network. However, the current researches on the operation of energy storage system are mainly focused on the optimization of time, and there are few of them involved in the optimization of the space. This paper presents a method for the control strategy of the two-stage energy storage system operation:in the first stage, it is the goal of the maximum benefit of the energy storage arbitrage and peak clipping, divides the time period of charging and discharging according to time-of-use price, all the energy storage systems are considered as a whole, and the total operation control strategy is formulated in the time period;the second stage is the second optimization of the space on the basis of the first stage, taking into account the network structure, the objective function is the maximum of the benefit of saving energy, the charging and discharging power of each energy storage system in each time period are distributed. Finally, a modified IEEE 33 node system is used as an example to verify the effectiveness of the proposed method.关键词
