论文摘要
在本文中，考虑了独立光伏分布式（SPVDG）系统的快速，有效和低成本控制的问题。当由于消除传输损失和不必要的能量转换而通过直流传输功率时，从这些系统中产生的现场生成更有效。这些系统的固有低惯性随着输出功率的波动和不确定的负载消耗而添加，呼吁采用高级控制技术，以确保在各种间歇性期间快速，稳定的操作。这些技术很昂贵，因为它们需要安装许多复杂的传感器。快速增长的IC技术提供的计算功率可用于估计系统中的不同参数，并减少对昂贵的传感设备的需求。这项工作为使用PV和电池的SPVDG系统开发了更快，更稳定和无传感器的电压控制和最大功率点跟踪（MPPT）的解决方案。
In this thesis, the problem of fast, effective and low cost control of a Standalone Photovoltaic Distributed Generation (SPVDG) system is considered . On-site generation from these systems is more efficient when the power is transmitted via DC due to elimination of transmission losses and needless energy conversions. The inherent low-inertia of these systems added with fluctuation of output power and uncertain load consumption, calls for advanced control techniques to ensure fast and stable operation during various intermittencies. These techniques are expensive since they demand installation of many sophisticated sensors. The computation power provided by the fast growing IC technology can be utilized to estimate different parameters in a system and reduce the need for expensive sensing equipment. This work provides solutions to problems encountered in the development of faster, more stable and sensor-free voltage control and maximum power point tracking(MPPT) for SPVDG systems with PV and battery.
