In this paper the authors have developed a hybrid renewable energy system. The studied structure comprises a wind energy generator, a shaded photovoltaic generator associated to an inertial storage system. The modeling of the global structure is developed and the control strategy is discussed. Conventional methods have been used to control the renewable sources. However, they may not have a suitable performance if the controlled system contains nonlinearity, as the wind turbine system or the shaded photovoltaic generator. In the presence of modeling uncertainties, the necessity of methods presenting controllers with appropriate performance as the advanced control strategies is inevitable. Fuzzy logic is used to control both the wind generator’s pitch angle and the maximum power point tracking (MPPT) of a shaded photovoltaic generator. The control of the storage flywheel, associated with the studied structure, to regulate the power supplied by renewable sources is also discussed. The design of the proposed strategy and its comparison with conventional controllers are carried out. The proposed method effectiveness is verified by MATLAB simulation results.

“…Research and implementation results have shown that the utilization of off-grid renewable energy-based systems, especially systems with distinct multiple energy sources (hybrid systems), are suitable for meeting the electricity needs of rural communities without electricity access. Moreover, the cost-effectiveness, minimization of greenhouse gas emissions, reduction in system losses and reliable electricity supply are among the many financial, environmental and technical benefits offered by well-engineered hybrid renewable energy systems [3].…”

This paper presents an optimized off-grid PV-diesel generator-battery hybrid energy system for application in an un-electrified rural community and further outlines a procedure for designing such an economical and technically feasible hybrid system. The hybrid optimization model for multiple energy resources (HOMER) software was utilized for simulation and analysis. The criteria of minimum net present cost of system, low CO2 emissions and zero electric load rejection was applied while considering technical issues of PV array, inverter coordination and PV capacity penetration level. For the case study system used, the obtained optimized hybrid energy system configuration is as follows: 68kW PV plant; 40kW Diesel plant; 45.4kW Inverter; and 80kWh battery unit. The proposed hybrid energy system is capable of producing 157685kWh of electricity annually at a levelized cost of energy of 0.55 $/kWh while emitting 51,000 kg of CO2 yearly. To avoid self-shading of the PV array, an appropriate inter-row distance was determined. The total quantity of PV modules and the electrical configuration of the PV array is presented.

Abstract-This project presents a solution for the design of a microgrid in Jaboneria, located in Chile considering technical and economic aspects. For the design of the microgrid, the reference time of project is 20 years and a limited budget of USD $ 250836, which is conceived as a Rural Electrification Budget. In order to produce a solution to the problem, HOMER PRO software is used. Sensitivity variables were taken into account, these include the variation of the electrical load, the state of charge of the batteries and renewable electricity generation systems. In addition other design parameters such as fuel cost, limitation residential electricity consumption, battery type, annual load profiles, fixed capital costs, etc.; were used. The cost of an Energy Management System (EMS) is not considered in the present analysis. Using HOMER, an optimal solution that combines the design parameters to find an efficient electrical energy production configuration that combines renewable energy sources (solar-wind), conventional generation (diesel) and battery power was produced, prioritizing clean energy. The optimal solution is obtained by evaluating the Net Present Value -NPC (USD $) according to each of the scenarios generated by sensitivity variables. A schematic of the system components and the corresponding load profiles are shown. Then, the information concerning renewable resources that exist in the study area and the technical-economic information of each system components was introduced. In addition, parameters of model are established. A social plan of energy-efficient consumption and citizen participation is also proposed. Finally, a simulation and analysis of the results of the scenarios generated by sensitivity variables of the system are presented. The chosen solution had the lower value of NPC and it contains the final sizing of each of the system components. This solution has to be of less value than the base budget of the project.
