A fuzzy logic controller for stand alone PV systems
Conference Record of the Twenty-Eighth IEEE Photovoltaic Specialists Conference - 2000 (Cat. No.00CH37036), 2002The main objective of this work is to improve the reliability of stand-alone PV systems by applying modern nonlinear control techniques to load management. The control technique implemented is based on load priority assignment and a fuzzy controller having two fuzzy variables and five fuzzy sets.

Sensitivity analysis of stand alone PV systems
Renewable Energy, 1996Abstract Daily solar insulation is stochastic quantity. Therefore there is always a risk for a stand alone PV system not to meet the load, loads fed by PV systems widely vary by the importance. Therefore there should be different risk level for different loads, eg the loss of load risk (LOLR) level for rural house could be much less than that for ...

Effective Power Management in a Stand-alone PV System
2018 53rd International Universities Power Engineering Conference (UPEC), 2018this paper deals with the energy management of the power flow in a stand-alone PV system, for the case of fast changing in weather conditions, and the case of rapid variation in the energy requirements of the customer. A super-capacitor is implemented as a storage unit to overcome the mismatch of energy between the load and the stand-alone PV system ...

System memory effects in the sizing of stand‐alone PV systems
Progress in Photovoltaics: Research and Applications, 2012ABSTRACTModels based on daily energy balance (or long‐term models) have been widely used as a tool in the stand‐alone photovoltaic (PV) system sizing, mainly with the purpose of obtaining analytical expressions of the relation between the generator size and the storage capacity of the battery.

Expert systems design of stand-alone PV systems for export
Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference, 1988Current system export practice is reviewed, and a promising export region, Nigeria, is selected and surveyed for resources and markets. An expert system design method is developed. The design optimization method appears promising for feasibility studies and optimal design of individual PV power systems. The life-cycle costs of the optimized PV drinking

Hybrid PV-diesel stand-alone system sizing for remote microgrids
2012 IEEE International Energy Conference and Exhibition (ENERGYCON), 2012This article focuses on the sizing of hybrid PV-Diesel stand alone systems. The sizing is performed taking into account the expected life of batteries and Diesel generators. A suitable model is proposed to determine an optimum configuration which minimizes long-term costs including external costs. The model is validated on a real life case-study.

A battery ageing model used in stand alone PV systems
Journal of Power Sources, 2002The authors present a new model for the ageing of a lead-acid battery which is based on the initial model of Shepherd. The proposed model allows to predict temporal variations of the Shepherd coefficients and to control the deterioration of the battery parameters and performances.
