Project: Electronic regulation – Study and realization of a device for energy management in a photovoltaic system.

Abstract:
The PV installation supply energy only during a part of time. During the night and by overcast weather, the supply of energy is worthless or insignificant. Batteries are thus necessary to store a part of the produced energy to be able to use it when the PV production is insignificant to cover the energy needs for the consumers.  At the moment, the storage of the electrical energy is mainly realized thanks to electrochemical accumulators. For reasons of cost and industrial availability, the technology lead-acid rather former is nevertheless the most used in the world. In a PV system, the function of the regulator is essential: batteries remain the most fragile elements of the chain and a better quality of their control and their maintenance improve the performances and the Period of life of the battery and thus eventually, the final cost of the kWh.

Objectives:

  • Study, conception and realization of a device intended for the regulation of the load and the discharge of the battery of accumulator in photovoltaic systems 
  • Study of the diverse types of converter DC / DC (Buck, Boost, Sepic, Buck-Boost, Boost-Buck)
  • Algorithms for the Search for the point of maximal power (Disturbance and Observation, Incremental Conductance, constant tension, constant current)
  • Techniques of artificial intelligence (logic swindles, network of artificial neurons, networks of neuro-fuzzy for the command of the static converter.
