Solar photovoltaic systems and hydropower generators play a major part in the utilization of renewable energy. In fact, these technologies have helped improve energy efficiency through independent power utilization of houses and businesses. By integrating technology in renewable energy to the agriculture sector, local farmers can enjoy the benefits of an improved harvest as well as more time for personal...
The problematic is to study the management of a hybrid energy system, depending on demand, dedicated to self-governing houses. Energy can be supplied by a photovoltaic panel, a wind turbine and a diesel generator and it can be stored in batteries. The study of this type of systems requires a good control strategy and an effective management. The main objective of this study is to develop a reliable...
This paper presents the design, modeling and simulation of hybrid power system driven by two sources of renewable energy. The first studied system is a photovoltaic generator, which is a DS-100M model consists of six models connected in series and it is linked to a DC/AC inverter where the MPPT controller, based on the Perturb and Observe technique, is applied. The second one is a small wind turbine...
A method for optimal sizing of hybrid system consisting of aPhotovoltaic (PV) panel, diesel generator, Battery banks and load is considered in this paper. To this end a novel approach is proposed. More precisely a methodology for the design and simulation of the behavior of Hybrid system PV-Diesel-Battery banks to electrify an isolated rural site in southern Algeria Illizi (djanet). This methodology...
The renewable energy based DG system is acquiring more attention towards the power industries due to their abundant availability which is cost free and eco-friendly, they are intermittent in nature too, hence the power prediction from one source is dependent. Thus, a hybrid DG system involving wind and solar energies can increase the power prediction over an individual. This paper presents, the DC...
This paper presents the design of a control strategy for Hybrid Photovoltaic — Battery Generator for Onboard Automotive Application. The proposed strategy is based on maximum power point tracking (MPPT) controller using adaptive fuzzy logic approach combined with an energy management supervisor in order to ensure system efficiency under variation of operating conditions: load requirements, meteorological...
Reasonable control of multiple energy forms for load power supply can effectively improve economy and reliability of micro-grid(MG) operation, however, up till now, these two problems of siting hybrid energy systems(HEMS) and scheduling them have been separately solved. In order to bring its flexible power supply capacity into fully play, this paper put forward an algorithm to optimally solve the...
Lebanon imports fuel oil to generate around 94% of its electrical power accompanied with high import fuel price, high losses which lead to electricity outages and environmental degradation. The electricity sector suffers from frequent power blackout of 3 to 16 hours per day in all cities in the country. More than 39% of electricity is generated from private diesel generators. Lebanon's geographic...
Levels of electricity access in sub-Saharan Africa are low with large populations living far from existing electricity infrastructure. This has led to interest in decentralized electrification solutions like microgrids, which can reach remote communities more quickly. To address a lack of capital to deploy these projects, governments have sought private investment in the sector. Studies have found...
The power produced from PV panel and wind turbine generators are based on weather condition, as a result this system is unreliable. The hybridization of this system with another source such as batteries or diesel generator increases significantly the reliability of the whole system. This paper recommends an optimization method of hybrid solar-wind battery systems based on BSA (Backtracking Search...
The aim of this paper is to present an approach to economically improve the overall performance, dependability, reliability and availability of electricity generation power plants in south of Algeria by integrating renewable energy. A prefeasibility study of a hybrid 9×1.9MW Diesel power generation plant in Tindouf (Algeria) from conventional and renewable energy sources will help to improve the performances...
This paper presents a review of different schemes of hybrid energy systems (HES) in islanding mode for remote areas with a focus on solutions for remote electrification which are basically composed by one or a mixed of different energy sources and storage systems. The paper analysis the widely used mathematical approaches for optimization, sizing and modeling of HES for isolated electrification areas...
A hybrid system utilizes several energy sources to generate electricity. This paper proposes combination of two renewable energies i.e. micro-hydro and photovoltaic for energy independent village application in Dusun Mergosari, Pesawaran Indah Village, Pesawaran Regency, Lampung Province. Previously, the village was only supplied by one micro-hydro generator through a long feeder line with high voltage...
While access to electricity in El Salvador is high, about 92% according to the World Bank, there are still many communities without access to power. Typically these communities are made up of poor, small villages in remote areas. Because they're difficult to access and because the populations are not sizeable, power providers and the government are slow or unwilling to bring power to them. This paper...
The supply of electricity to the rural villages in the south of Algeria where the dispersion of population is very important and the increase in the rate of consumption of electrical energy constitute two major problems encountered by the company of electricity in Algeria. Electricity generation in large southern Algeria is based primarily on diesel power production with enormous technical, economic...
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...
