  • Influence of exogenous and endogenous factors on the exergy analysis of 3–column array wind farm

    Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and distance between turbines. Endogenous factors considered were diameter of rotor, hub ...

  • Wind power has increased by 175 MW in Spain in 2013, the lowest rate of growth in 16 years

    The wind sector installed 175 MW in Spain in 2013, up 0.77% on a year-by-year basis. This is the lowest growth rate in the sector since 1997, the year in which it was regulated for the first time in the Electrical Sector Law. On December 31st total accumulated power in the sector stood at 22,959 MW according to data compiled by the Spanish Wind Energy Association (AEE). This installed power is ...

  • Development of PSO-based robust controller for maximising wind penetration

    In this paper, a new robust controller has been proposed for attaining the maximum safe instantaneous wind penetration. Particle swarm optimisation (PSO)-based algorithm has been developed to obtain the maximum safe instantaneous penetration by the optimisation of grid parameters. The developed algorithm has been tested on modified IEEE 14-bus system. The effectiveness of the proposed methodology ...

  • Operation and control of multiple Distributed Generation systems in the microgrid

    This paper investigates the operation and control of multiple Distributed Generation (DG) systems interconnected to the utility in the form of microgrid. The developed model of the microgrid consists of microturbine generation system, converter-based DG system with stiff DC source, synchronous-generator-based DG system and wind power system with induction generator. The Simulation model of the ...

  • Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica

    Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

  • 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 ...

  • Numerical methods for investigation of destructive wind energy dissipation by bridges

    Many bridges are located at especially unfavourable places considering the local wind power and turbulence. Therefore it turns out that finding an optimal balance between structural safety and erection costs depends strongly on a proper wind modelling and investigation. Several aspects must be taken into account for the wind design. The effect of wind gusts and randomly distributed wind velocity ...

  • Wind energy generators sitting and sizing based on uncertain generation pricing

    This paper proposes a methodology for sitting and sizing wind distributed generators (WDGs). These generators are characterised by an uncertain active power production due to the random behaviour of the wind speed. The uncertain generation directly impacts the network total generation cost and also the solution for the placement and sizing problem. So, this work takes into account this uncertain ...

  • Efficiency stimulus will lower energy bills, says federal report

    Depending on your position, the federal stimulus money is either a jobs builder or a national budget buster. The Energy Information Administration offers another take. In a recent analysis, the EIA finds that stimulus money should reduce what consumers and businesses pay to heat, cool and light buildings. The federal agency this month updated its annual energy outlook to compare how energy ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • Dispachability improvement of wind generation by the Virtual Power Producers

    Today, there is a growing environmental concern about where the energy that we use comes from, bringing the attention on renewable energies. However, the use and trade of the renewable energies in the market seem to be complicated because of the lack of guarantees of generation, mainly in the wind farms. The lack of guarantees is usually addressed by using a reserve generation. The aggregation of ...
