Expanding the markets for advanced photovoltaic (PV) energy harvesting applications depends on the use of power management methods and electronic systems that implement efficient processes to maximize power generation. The research presented in this dissertation is the result of a response to such demands, presenting novel techniques which aim at facilitating the energy management in photovoltaic systems and electricity grids, in general.The main target of this PhD thesis is to research a series of novel techniques which can work either as single approaches to serve the aforementioned purpose, but also to allow for their combination to create low-power, low-complexity, and low-cost devices dedicated to be embedded in a single power source (either a PV cell or a set of PV cells). The goal is to enhance the controllability of the overall system, to improve its power efficiency, and to increase the amount of status information received by every unit involved, rather than shared aggregated values of telemetry data. This also translates to a maintenance service upgrade by expediting any failure diagnosis, simplifying its serviceability and minimizing any out-of-order costs. In this PhD thesis, novel electronic systems are presented for:- the maximization of the power produced by photovoltaic cells,- the management of the energy produced by photovoltaic cells,- the addition of status monitoring capabilities to distributed DC power sources,- the addition of operational controlling capabilities to distributed DC power sources.Experimental prototypes of the proposed electronic energy management systems have been developed and their successful operation has been validated by experimental results.
