A novel dual stator-winding induction generator system applied in wind power generation
This paper presents a novel usage of 6/3-phase dual stator-winding induction generator (DWIG) with a static excitation power controller (SEC) as a wind power generator. This generator is composed of a standard squirrel-cage rotor and two sets of winding housed in the stator slots. One is referred to as the 6-phase power winding, and the other is defined as the 3-phase control winding. On the ...

Wind Turbines and Shadow Flicker Impacts
According to the International Energy Agency (IEA) wind electricity generation increased by 17% in 2021, up by 55% from the growth in 2020, and experienced the highest growth when compared to other renewable energies. With the steady increase in wind power generation, the likelihood of environmental impacts, albeit much lower than fossil fuel power generation, are becoming more prominent ...

Power losses from wind generated electricity in high voltage AC transmission: an analysis through simulation
In this paper, we have investigated different types of losses from wind generated electricity in high voltage AC (HVAC) transmission. Wind power generation is expensive in nature and it is thus necessary to know how much power is lost in the transmission. We have simulated an HVAC transmission system with a wind power generator in Simulink. We varied different components of the system namely wind ...

Study on environmental impact model of grid-connected wind power generation
As a clean and renewable energy source, wind power is independent from the traditional external energy change, which makes it one of the most promising ways of clean energy generation. It is well known that wind power has obvious energy saving efficiency. But for long-term consideration, wind power generation still has certain impacts on human life. Therefore, standing in the point of the ...

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 ...

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 ...

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 ...
