| 摘 要： | 该文提出一种具有高压穿越能力的基于三端口能量路由的单级式光储并网系统（PV-ESS）。光伏最大功率跟踪始终由三相变换器控制完成。多端口能量路由器可根据不同运行工况使储能灵活接入,平抑光伏输出,使得系统具有更高的效率。在电网高压故障下,通过储能装置抬升直流母线电压,从而使系统具有高压穿越的能力,可在电网高压状态下不脱网连续运行,直至故障恢复。

| Abstract: | This paper proposed a single-stage photovoltaic grid-connected system integrated energy storage system （PV-ESS） based on three-port energy routing with high voltage ride-through capability. The maximum power point tracking （MPPT） of PV is controlled by the three-phase AC/DC converter. The multi-port energy router can flexibly access energy storage according to different operating conditions, to stabilize the photovoltaic output, which makes the system more efficient. Under the power grid high voltage fault, the DC bus voltage is raised by the energy storage device, so that the system has the ability of high voltage ride-through, and can run continuously without disconnecting the grid under the high voltage state until the fault recovery. |
