摘要
为研究光柴储独立微电网,提出了该系统的结构、组网形式,并对其运行时的系统内各元件的协调控制策略进行了详细描述。该协调控制策略将光伏最大功率跟踪控制、蓄电池充放电控制及柴油机控制相结合,在保证微电网电能质量的前提下,最大化地利用光能、减少柴油消耗,提供供电稳定性。仿真模型验证了上述控制策略的正确性,结果表明,该控制策略能协调光柴储微电网各部分的能量流动,使之合理有序运行。
To study isolated microgrid composed of diesel,photovoltaic and energy storage battary,structure and network form are proposed and the coordination control strategy for the system aredescribed in detail.A control strategy,in which the maximum power point tracking control is combined withengine control,storage battery charging and discharging control,is putforward to maximize use of solar energy,reduce the diesel consumption and improve power supply stability.Simulation results show that the proposed control strategy can coordinate power flow of each part of the microgrid,make a reasonable and orderly operation.
