本发明公开了种用于协调配电网储能系统充放电效率的分布式控制方法，包括下述步骤：步骤10)测算本地功率缺额：步骤20)实现功率缺额的共享，获取系统总功率缺额：步骤30)测算每个储能系统的边际充电成本，确定预设的牵制致性值；步骤40)通过牵制控制使各储能代理达到牵制致性；步骤50)调整配电网中储能系统的充电功率。该控制方法是种完全分布式的控制方法，能够以分布的方式实现全局信息共享，满足分布式单元即插即用操作的需求，并考虑边际充电成本和充电状态，对储能系统的充电功率进行精确调整，从而协调优化配电网中各储能系统的充放电效率。 The invention discloses a distributed control method for coordinating the charging and discharging efficiency of the energy storage systems of a power distribution network. The method includes the following steps that: step 10) local power shortage is calculated: step 20) the sharing of the power shortage is realized, and the total power shortage of the systems is obtained; step 30) the marginal charging cost of each energy storage system is calculated, a preset pinning consistency value is determined; step 40) each energy storage agency is made to achieve consistency through pinning control; and step 50) the charging power of the energy storage systems in the power distribution network is adjusted. The control method is a completely distributed contro
