Topology reconfiguration for optimization of photovoltaic array output [PDF]

Sustainable Energy, Grids and Networks, 2016
As more utility scale photovoltaic (PV) power plants are installed, there is a need to improve monitoring and management of PV arrays. A procedure is presented here for optimizing the electrical configuration of a PV array under a variety of operating conditions. Computer simulations and analysis with synthetic and real data are presented in this paper.

Dynamic Reconfiguration to Optimize Energy Production on Moving Photovoltaic Panels

Sustainability, 2023
Urban transport systems play a major role in the development of today’s societies, but they require technological changes to reduce their environmental impact. The problem lies in their level of autonomy, which is why electrical energy production systems are proposed for self-consumption, efficiently feeding their accumulators.
