Telstra's telecommunication network covers a diverse area, which is subject to Australia's challenging environmental factors. These factors present challenges to the network and can prominently affect Telstra's remote sites, especially off-grid sites. This paper presents the key findings of using stationary fuel cells at these remote sites. The fuel cells implemented by Telstra are indirect methanol...
In Morocco, the use of renewable energies present have a great importance especially with the new energy strategy. The important geographical location of the Kingdom helps for the development of the use of the solar energy. To reduce the import of primary energy, and to make face to the high demand of electricity and water in remote zone, the government has made several projects to encourage the use...
Hybrid between PV and Generator with battery is one common technology that has been used in the world due to meet the system with the presence of renewable energy. These systems are typically used in isolated area or areas away from the grid. In this paper the hybrid PV-Generator with battery power plant will be designed for Aha Village in Morotai Island which is one island in Indonesia that located...
this paper presents results on the simulation, modeling and optimization of an off grid hybrid solar PV/diesel/battery/inverter power system for residential application. The principal objective is to design a standalone renewable energy system to meet the desired electric load with high renewable fraction, low excess power and low cost of energy. Hourly simulations and optimization were performed...
This paper investigates the impact of incorporation of renewable energy (RE) resources on diesel generation carbon footprint reduction in Canada's remote communities. A multiple-year planning optimization problem is adopted to study the feasibility of integration of RE and energy storage system (ESS) in isolated microgrids of remote communities and to verify the economic and environmental benefits...
Ilakan community in South-West Nigeria, with a population of about 300 dwellers, has had no access to any form of electricity since its existence. A large percentage of the population is very active and engages in productive activities, predominantly farming. This paper aims at providing affordable, clean, off-grid electricity to the community by designing a decentralized energy hub where residents...
Today, the world is very much concerned about the global warming effects due to the increasing pollutant emissions from various sectors of manufacturing industries. They are majorly using coal based power plants for fulfilling their electricity need. The requirement is of switching some partial load on renewable system and finding alternative fuels that can help in reducing green house gases' emissions...
The outback of Australia is characterised by its remoteness from traditional electrical energy supplies and vast distances between inhabited areas which impede supply of commodities. Insular power systems are typical solutions for such localities, usually consisting of a generator energised by diesel fuel or liquefied petroleum gas. In this paper an enhanced, hybrid system is considered by adding...
A microgrid for the purpose of reducing the fuel consumption at the Japanese Showa Base in the Antarctica is being considered due to the increase in fuel consumption in the base caused by the continuous increment in research activities. In this paper, the planning of the operation of the engine generators at a representative day using a simplified mixed integer programming is proposed for this microgrid.
Hybrid renewable energy systems shows a great potential for electricity generation in Bangladesh. Hybrid renewable energy system can be set up such a way that the electricity will add to national grid connection and it will eventually reduce the pressure of electricity demand from national grid. Abundance of renewable energy sources in the form of solar energy provides opportunities of renewable energy...
The constant increment in the penetration of renewable energy sources requires the improvement of the flexibility of the power system. Due to its high generation cost, it is expected that insular power systems experience an important increment in the power generation from renewable energy sources and, under this perspective, an energy storage system (ESS) could be the key factor to meet this goal...
Due to existing conflicts or natural disasters in many different parts of the world, refugee camps are established by different aid organizations in order to provide local humanitarian assistance. Nowadays, these camps are electrically supplied using diesel generators, which are not environmentally friendly and require huge amounts of not easily available fossil fuels. In this sense, Microgrids (MGs)...
Energy shortage is one of the major impediments to social, industrial and economic growths in developing countries. For instance, only about 40% of Nigeria's population (about 170 million) has access to electricity. Due to this, petrol/diesel generators are used for electricity generation in various sectors of the country, which are not eco-friendly. Though developing countries are thought to emit...
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...
Remote microgrids are a viable option for electrification where the main grid expansion is either impossible or not economical. Typically, remote microgrid consists of diesel generator as a primary source of energy which has a high fuel cost. Renewable energy sources can be used to reduce the fuel consumption with proper coordination and scheduling methods. Storage devices, usually battery, used in...
In the case of ensuring the reliability of power supply, in order to improve the economy of the distributed generation systems, it should be based on different resource conditions to optimize the design of the system. This paper constructs the distributed power generation system structure of multiple distributed power supply. The main factors affecting the optimal design are discussed qualitatively...
This paper proposes a methodology for configuring hybrid solar-wind-diesel-energy systems at minimum cost and minimum dumped load. An iterative optimisation technique has been developed to calculate, the optimum system configuration to achieve minimum hours of loss of power supply and minimum annualized cost of system (ACS). The decision variables included in the optimization process are the number...
Renewable energy sources are utilized for various stand alone applications in the present energy scenario. However, these renewable energy sources are diluted, site specific and also unpredictable in nature. Hence, more than one energy sources are integrated as a Hybrid Energy System (HES) to provide electricity especially for rural areas. When energy sources of different characteristics are integrated...
The aim of this paper is to demonstrate that a dynamic simulator, taking into account temporal data of renewable sources and using energy on one year, is able to sizing each element composing the electric generation system and the storage system. The electrical system includes photovoltaic panels (PV), a wind turbine (WT), a diesel generator (DG) and a storage battery. To illustrate the sizing capability...
Remote areas in Australia are mostly powered by conventional diesel generators (DG). These systems face challenging tasks of increasing diesel costs, transportation of diesel over long distances, increased fuel consumption and maintenance costs associated with running the DGs in low load conditions. Furthermore, regulations by governments and lobbying by environmental activists are rising due to the...
