由于蓄电池具有良好的储能特性以及可控性,电动汽车换电站运营商在满足换电需求的前提下,可以响应电网企业的激励措施,达到系统运行的要求。首先,根据换电站内电池组的状态参量,建立电池组的状态矩阵;其次,将电池组进行状态分群,对其中处于可控状态的电池组实施控制;最后,运用递推的思想研究该换电站内备用电池组的可控负荷裕度带,进而指导换电站运营商根据电网企业的运行目标制订相应的充电计划,达到负荷平衡、改善区域负荷特性等目的。
Due to its good energy storage characteristics and controllability, EV battery station operators can meet the requirements of system operation in response to the incentive measures of grid enterprises on the premise of meeting the demand of power exchange. Firstly, the state matrix of the battery is established according to the state parameters of the battery in the substation. Secondly, the state of the battery is divided into groups to control the battery in the controllable state. Finally, the recursion is used to study the change The controllable load margin band of the backup battery pack in the power station instructs the station operator to formulate the corresponding charging plan according to the operation objectives of the power grid enterprises to achieve load balancing and improve the regional load characteristics.
