| dc.description.resumo | World energy demand is increasing in the same proportion as the population density and its electrical energy supply comes largely from the use of fossil fuels, whose main characteristic is their negative impact on the environment. However, renewable energy resources represent a major alternative in the energy matrix that can reduce the environmental problems caused by fossil fuel sources while addressing this global energy demand. The contribution of solar energy indirectly from other renewable energy resources makes it even more special to develop the direct exploitation of solar energy resources. Thus, due to the ease of implementation at any size of a solar system and the decreasing price of solar modules on the world market, its exploitation has been promising and the development of all the elements that make up a photovoltaic system has been receiving special attention from the scientific community and some industrial sectors. However, depending on the use of the solar system or the desired energy efficiency of the system, it would be appropriate to use a battery storage system to store the excess energy produced by the PV modules. This thesis presents an off-grid solar photovoltaic system with a lead acid battery bank that highlighting a control strategy through a dual-stage cascaded energy conversion topology which is composed of an MPPT boost DC-DC converter at the input, an DC-DC interleaved bidirectional battery-bank converter and also a DC-AC inverter. The objective of the proposed control strategy is to adequately control the power flow through the DC-DC MPPT converter, the DC bus independently of the solar irradiation and the DC-DC interleaved bidirectional battery-bank converter that responsible to charge/discharge the battery-bank while providing power to the AC loads. To achieve this objective, the power injected into the DC link is controlled using two integrated control loops that calculate the difference between the input and output power levels to inject or extract it from the battery bank under different operating points. Simulation results are included for a 1.6 kW PV system to validate the proposed control strategy. | por |
