摘要
随着配电网中新能源接入比例的不断提高,配电网负荷低谷时刻的弃风弃光现象日益严重。为了提高配电网对新能源的消纳比例,提升分布式储能的运行收益,首先对分布式储能系统在配电网的应用进行了需求分析,明确了利用分布式储能系统提升新能源消纳比例的合理性。然后,构建了分布式储能系统优化配置方法,兼顾了储能系统的套利收益及其投运成本,以储能系统日运行净收益最优为目标,研究分布式储能系统的优化配置。最后,利用IEEE 33节点算例系统验证所提出方法的有效性,结果证明所提出的储能系统配置方法在提升配电网对新能源消纳比例的同时,提升了配电网运行的安全稳定性。
With the increasing proportion of new energy in distribution power grid,the phenomenon of abandoning wind and light in off-peak load of distribution power grid becomes more and more serious.In order to improve the proportion of new energy consumption in distribution power grid and improve the operating income of distributed energy storage system,firstly the demand for the application of distributed energy storage system in distribution power grid is analyzed,and the rationality of using distributed energy storage system to improve the proportion of new energy consumption is made clear.Then,a distributed energy storage system optimal allocation method is constructed,which takes into account the arbitrage benefits and operation costs of energy storage system,and studies the optimal allocation of distributed energy storage system with the goal of optimizing the net income of energy storage system daily operation.Finally,the effectiveness of the proposed method is verified by the IEEE-33 node example system.The results show that the proposed energy storage system configuration method not only improves the proportion of new energy consumption in the distribution power prid,but also improves the safety and stability of the distribution power grid operation.
