The research topic formulated initially concerned the study and the development of an
optimal strategy for the operation of hybrid energy systems based on renewable energy.
To do this, we theoretically and experimentally studied some photovoltaic systems. The
procedure was the analysis of the internal and external parameters of photovoltaic cells based on the code data of the illumination measurements, the temperature over a long period. We studied the theory of wind systems and performed experiments on an experimental system developed locally.
We studied the theoretical models for the production of methane by anaerobic digesters, and carried out experiments on an experimental digester performed locally. We studied the theory of photothermal systems and conducted tests on photo-thermal developed locally.
Given the energy loss during conversion and regulation, we studied the conversion of
electrical energy from Renewable Energy systems. We conducted the study and choppers prototype simulation PWM (Pulse Width Modulation) to minimize energy conversion losses. The systems considered are nonlinear systems with more or less filter first and second order.
To reduce the cost of energy system based on a single renewable resource; we have adopted an approach of considering based on zonal characteristics and demand, the combination of two or more renewable resources that are available (solar photovoltaic, solar photo-thermal, wind power, biogas obtained by anaerobic bio reactors).
We used an optimal allocation of management resources ER model that exploits the internal and environmental characteristics. Linear programming model has been used in the case where resources are continuous and in case where these resources are discrete units, they also available.
The program is generic and can be used for any other ER resource provided to present the expression that connects the internal annual energy and environmental characteristics.
