This paper presents a techno-economic assessment for a unique Isolated Hybrid Power System (IHPS) design for remote areas isolated from the grid which also has the capability of being operated as a smart μ-grid. The share of renewable energy sources in resource poor developing countries is low. In these countries an increase in the share of alternative energy (wind, water and sun) delivered with inexpensive...
This paper deals with the optimal design of a stand-alone hybrid photovoltaic and fuel cell power system without battery storage to supply the electric load demand of the city of Brest, Western Brittany in France. The proposed optimal design study is focused on economical performances and is mainly based on the loss of the power supply probability concept. The hybrid power system optimal design is...
This paper focuses on unit sizing of stand-alone hybrid energy systems using bees algorithm. With different combination of renewable sources, two types of hybrid energy systems are taken as test systems. Apart from the non-conventional sources like wind turbines, solar panels along with micro hydro plant, the systems have been optimized with fuel cell, converters, electrolyzers and hydrogen tanks...
In this paper, the effect of PV/FC hybrid power generation system on total line loss of distribution network has been studied. Studies have been conducted on a real life 20 kV distribution network. A DPL (DIgSILENT Programming Language) code is developed to analyze the effect of the PV/FC hybrid system on total line loss in distribution network. Simulations, in three loading conditions and by considering...
In this paper a hybrid stand alone energy system for telecom applications in minor islands is presented. Simulation models have been developed to verify the system performance under different scenarios using practical load profile and meteorological data for the island of Ventotene in Italy. Simulation results are given and discussed for both winter and summer scenarios. The results show that the...
This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system. The paper focuses on the combination of solar cell (SC), wind turbine (WT), fuel cell (FC) and ultra-capacitor (UC) systems for power generation. As the wind turbine output power varies with the wind speed and the solar cell output power varies with both the ambient temperature and radiation,...
In this paper, a small hybrid power generation system comprising a wind turbine and a fuel cell is simulated. Due to the fluctuating nature of wind power, another energy source should be integrated with the wind turbine to ensure reliable and efficient operation of the power system. Dynamic simulation of a wind fuel cell hybrid energy system is performed, and the results are presented. This study...
This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system. In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other. The paper focuses on the combination of solar cell (SC), wind turbine (WT), fuel cell (FC) and ultra- capacitor (UC) systems for power generation...
The major application of the stand-alone power system is in remote areas where utility lines are uneconomical to install due to terrain, the right-of-way difficulties or the environmental concerns. The wind power output can fluctuate on an hourly or daily basis. The stand-alone system must, therefore, have some means of storing energy, which can be used later to supply the load during the periods...
This paper presents a methodology for the design of an autonomous renewable energy system with fuel cell as the back-up generator to supply electricity to a reverse osmosis desalination plant. The sizing of system's units is based on an operational algorithm that considers the operational features of the system. Since the algorithm generates several workable designs, of importance is only the optimal...
In this paper a novel intelligent method is applied to the problem of sizing in a hybrid power system such that the demand of residential area is provided. The system consist of fuel cells, some wind units, an electrolyzer, a reformer, a compressor, an anaerobic reactor and a hydrogen tank. The system is assumed to be stand-alone and uses the municipal waste as an available energy resource. PSO algorithm...
The hydrogen economy concept is a controversial and timely topic of the day. Power electronic rich fuel cell cars are seen as one of the key building blocks to integrate hybrid electrical power networks, including electrical, gas and hydrogen with renewable energy sources including wind and solar. These fuel cell cars equipped with power electronic interconnections bring new challenges to these networks...
