The bidirectional DC-DC converters are widely used in battery charging /discharging scheme. The dual active bridge scheme is adopted for the high power applications. The wide voltage variation requirement of battery charging and discharging can be fulfilled with the additional stage along with the dual active bridge. Isolated boost converter can also meet the wide voltage variation requirement. The...
In this study, Biogeography Based Optimization (BBO) algorithm is developed for the prediction of the optimal sizing coefficient of Small Autonomous Hybrid Power System (SAHPS) in remote areas. BBO algorithm is used to evaluate optimal component sizing and operational strategy by minimizing the total cost of SAHPS, while guaranteeing the availability of energy. Due to the complexity of the SAHPS design...
When the stand alone energy system having photovoltaic panels only or wind turbine only are compared with the hybrid PV/wind energy systems, the hybrid systems are more economical and reliable. Hybrid system can be able to adapt the effects due to climate changes. This paper presents a Artificial Intelligent method to design the hybrid PV/wind system. While meeting the basic requirements of the stand-alone...
In order to evaluate the techno-economic performance of Hybrid Energy System for remote rural area electrification, a mixed integer linear mathematical programming model (time-series) has been developed to determine the optimal operation, optimal configuration including the assessment of the economic penetration levels of photovoltaic array area, and cost optimization for a hybrid energy generation...
This paper presents the results of the application of model (developed in Part-I) and simulation algorithm (developed in Part-II) for determining the techno-economics of battery storage type hybrid energy system intended to supply the load demand of a rural remote area having a cluster of nine villages (grid isolated). The hour-by-hour simulation model is intended to simulate a typical one month period...
A well designed hybrid energy system can be cost effective, has a high reliability and can improve the quality of life in remote rural areas. The economic constraints can be met, if these systems are fundamentally well designed, use appropriate technology and make use effective dispatch control techniques. The first part of this tri-series paper, presents the analysis and design of a mixed integer...
Computer simulation is an increasingly popular tool for determining the most suitable hybrid energy system type, design and control for an isolated community or a cluster of villages. This paper presents the development of the optimum control algorithm based on combined dispatch strategies, to achieve the optimal cost of battery incorporated hybrid energy system for electricity generation, during...
