A hybrid wind/solar/diesel stand alone system optimisation for remote areas in Algeria
While Algeria has an important potential of wind and solar energies, their share in the primary energy supply is relatively low compared to the fossil energy. In this paper, we propose to carry out a techno–economical study of a hybrid stand alone system in order to draw the attention to the feasibility of such systems. For this purpose, sites of Hassi–R'mel and Adrar have been ...

Renewable Energy Market in Indonesia
The development of renewable energy in Indonesia has stalled in recent years, especially wind and solar PV power. By the end of 2018, cumulative installed solar and wind capacity in Indonesia just reached 136MW, which is at a relatively low level compared with other Southeast Asian countries. It is a recognized fact that 2019 was the year of Vietnam’s renewable energy explosion, with a new ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...

Optimal scheduling and operation of hybrid biomass/wind/PV energy system for rural areas
In this paper, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV) and battery, is proposed. The sources are operated to deliver energy at optimum efficiency. An optimisation model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with ...

Energetic and exergetic assessment of solar and wind potentials in Europe
This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

The Water-Energy Nexus
Different types of electricity generation require differing amounts of water. Except for photovoltaic solar and wind power, which require no water to produce energy. However there is a substantial water requirement for all forms of electricity generation in making the raw materials and constructing and maintaining the plant. Thus although wind-power has a very low water ...

Renewable Energy Systems - Case Study
Overview Generating renewable electricity is an important way to reduce carbon dioxide (CO2) emissions and many countries are installing wind and solar power plants to help meet targets for cutting CO2. One drawback of these energy sources is their variability: the wind tends to blow intermittently and solar power is only available during the daytime. Hence renewable power plants either have to ...

Application of genetic algorithm and neural network for sizing of hybrid photovoltaic wind power generation (HPVWPG) systems
In this paper, a methodology for sizing of hybrid photovoltaic-wind power generation (HPVWPG) system is described. The purpose of this methodology is to predict the PV-generator area, the capacity of the battery and the capacity of the wind generator in isolated (remote) areas, where the meteorological data (solar irradiation, air temperature, wind speed, etc) are not always available. For this ...

How will this new development in batteries make wind and solar power more completive?
The trend is changing in obtaining energy from conventional sources to obtaining energy from solar and wind power units. The change in trend is due to this energy is considerably cheaper than the energy obtained from several other methods. Earlier an expensive metal was used over in the chargeable batteries for solar and wind units. Mostly these units contain platinum and other very expensive ...
