Method and system for extracting electrical power from renewable energy sources

Abstract

The plant comprises: a DC-voltage electric power source (3), whose operating conditions vary as a function of at least one uncontrollable quantity, for each value of the uncontrollable quantity the source presenting a characteristic curve of the supplied power as a function of a controlled quantity, wherein each characteristic curve presents a maximum for an optimal value of said controlled quantity; a power conditioning circuit (5); a regulation loop (9) to adjust the controlled quantity maximizing the power supplied by the source when said uncontrollable quantity varies. The regulation loop is designed in such a way as to determine whether, for the actual value of said uncontrollable quantity, the actual value of the controlled quantity (V.in) is greater or lower than the optimal value and to generate a regulation signal (V.in-REF) to modify the actual value of the controlled quantity towards the optimal value.

Description

technical field [0001] The present invention relates to the development of alternative energy sources, more specifically, the development of renewable energy sources. Specifically, although not exclusively, the present invention relates to improvements in methods and systems for harnessing solar energy with photovoltaic panels. [0002] More generally, the present invention relates to improvements in methods and systems for extracting power from a source whose operating state varies with at least one uncontrollable quantity and for each value of the uncontrollable quantity with the power supplied varying with the control For each value of the uncontrollable quantity, the characteristic curve has the maximum value for the optimal value of the control quantity. Background technique [0003] Renewable energy sources are gaining in importance due to the increasing demand for energy and problems associated with the depletion of conventional energy sources, as well as the environ...

Problems solved by technology

[0009] These algorithms are efficient, but they exhibit certain limitations, mainly related to the fact that a sudden change in the radiation state takes a long time for the system to adapt to the new operating state due to the fact that the change in the radiation state causes the system to have to be on The characteristic curvature of the move changes
