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.

实现对独立 PVDG 系统的快速、灵活和无传感器控制

本论文研究了独立光伏分布式发电(SPVDG)系统的快速、有效和低成本控制问题。由于消除了传输损耗和不必要的能量转换，当电力通过直流传输时，这些系统的现场发电效率更高。这些系统固有的低惯性加上输出功率的波动和不确定的负载消耗，需要先进的控制技术来确保在各种间歇期间快速稳定地运行。这些技术是昂贵的，因为它们需要安装许多复杂的传感器。快速发展的 IC 技术提供的计算能力可用于估计系统中的不同参数，并减少对昂贵传感设备的需求。
