There is a need to develop an optimization tool that can be applied in the feasibility study of hybrid renewable energy system find optimal capacity different resources and support decision makers their performance investigation. A multi-objective function which minimizes Levelized Cost Energy (LCOE) Loss Load Probability Index (LLPI) but maximizes novel Match Ratio (EMR) was formulated. Simula...

In this paper, an optimal design of the renewable combustion plant has been investigated with the aim of ensuring the required load on the Gorgor station. The purpose of this study is to minimize the cost of the proposed hybrid unit during the period of operation of the designed system simultaneously. Information on the intensity of solar radiation and the intensity of wind blowing in the area ...

As climate concerns, low natural gas prices, and renewable technologies increase the electric power sector’s dependence on natural gas-fired power plants, operational and investment models for gas and electric power systems will need to incorporate the interdependencies between these two systems to accurately capture the impacts of one on the other. Currently, few hybrid gas-electricity models ...

This paper determines and compares the cost of energy (COE) of various hybrid systems for several off-grid facilities in North and Far North regions of Cameroon by integrating renewable sources and/or storage with diesel generators. The estimated annual energy production by solar PV systems and wind turbines is also discussed. The aim is to study the application of a high penetration renewable ...

In many cases grid extension is often highly costly and unlikely to happen – even in the mediumto long-term. In these scenarios, mini-grids (MG) could provide an ideal intermediary solution, especially for small towns or large villages where enough electricity can be generated to power household use, as well as local businesses. MGs provide centralized electricity generation at local level usin...

Energy usage, dependability of energy supply and climate change are important topics in society. Today, a number of trends can be recognized in the electricity consumption and generation. On the one hand, the electricity consumption increases and becomes more žuctuating. is is caused by increasing economic activity and prosperity, but also by a shiŸ towards more electricity supplied devices, fo...

Energy systems operation in isolated areas is frequently based on imported fossil fuels, which is a problem in different dimensions including environmental, economic and security of supply, with the latter being particularly relevant for any isolated system like Islands. Renewable energy is regarded as a solution to this problem, mainly in its transformation to electricity. This, however, exclu...

Renewable energy sources i.e.,energy generated from solar, wind, biomass, hydro power, geothermal and ocean resources are considered as a technological option for generating clean energy. But the energy generated from solar and wind is much less than the production by fossil fuels, however, electricity generation by utilizing PV cells and wind turbine increased rapidly in recent years. This pap...
