This paper describes a methodology developed for designing an optimal configuration for system transmission planning with carbon emissions costs. The power transmission network planning problem is modeled by the mixed integer programming model, a GA, and SA. At this moment environmental issues...

In the design of a wind farm, the placement of turbines is an important factor that affects the efficiency and profit, but automatic placement of turbines is still a challenging problem.

In this paper, the dynamic performance of grid connected Wind Energy Conversion System (WECS) is analysed in terms of the newly defined concept of rotor speed stability. The WECS is considered as a fixed-speed system that is equipped with a squirrel-cage induction generator. The drive-train is...

The intermittent wind power in a stand-alone microgrid power system may cause a serious problem of frequency fluctuation. Energy storage (ES) such as a battery, super capacitor, superconducting magnetic energy storage (SMES) etc., can be used to reduce the frequency fluctuation. However, ES is...

The characteristics of turbine spacing for optimal wind farm efficiency were investigated using combined numerical models. The effects of wakes from upstream turbines were predicted by a model capable of determining velocity distributions on a rotor plane, based on Ainslie's approach. The...

The joint challenge of global pollution and depletion of fossil fuels is driving intense search into alternative renewable sources. This paper reports the modeling and optimization of biogas production on mixed substrates of saw dust, cow dung, banana stem, rice bran and paper waste using...

In this paper, an artificial neural network-based genetic algorithm (ANN-GA) model was developed for generating the sizing curve of stand-alone photovoltaic (SAPV) systems. Firstly, a numerical method is used for generating the sizing curves for different loss of load probability (LLP)...

Photovoltaic (PV) generation of electricity is an important renewable energy source. One way to increase the value of small-scale renewable generators is to aggregate and control their output so they appear to the wider grid as one larger generator. This paper introduces our Virtual Power...

In the present study, the placement of wind turbines in wind farm has been resolved with a new coding and also a novel objective function in Genetic algorithm approach. In comparison to previous works, the results have been noticeably improved. The presented objective function, with its...

The increase in wind energy penetration is creating a wide range of technical problems in power networks. Reactive Power Planning is one of these crucial issues which entails all the necessary planning actions to improve the voltage profile as well as the voltage stability in power networks. On...
