摘要

提出了一种家用纳米电网能源管理系统的控制策略。提出的EMS是基于状态图的。选择了一种具有直接存储能力的三端口变换器(TPC)，并定义了状态和状态转换。状态图向两种算法发送信号，其中一种算法计算电池基准电流，另一种算法允许光伏(PV)系统始终在最大功率点运行。在MATLAB/Simulink中使用通用模型实现了一个扩展模型来测试所提出的控制方法。结果表明，该系统始终遵循与电网的指定功率交换，功率超调为500W，最坏情况稳定时间为500ms。

Control of a three-port DC-DC converter for grid connected PV-battery applications

A control strategy for an energy management system (EMS) of a household nanogrid is presented in this paper. The proposed EMS is based on a state diagram. A three port converter (TPC) with direct storage capability is chosen and the states together with the state transitions are defined. The state diagram signals to two algorithms of which one calculates the battery current reference and the other allows the photovoltaic (PV) system to operate at the maximum power point (MPP) at all times. An extensive model has been implemented in MATLAB/Simulink using generic models to test the proposed control method. Results show a system which at all times follows a specified power exchange with the grid with a overshoot in power of 500W and worst case settling time of 500ms.
