in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...
To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...
the remarkable development of sciences and technologies in the world of]o today has apparently brought mankind comfort and well-being, but it has also created new problems for humans including environmental pollution, widespread changes in world weather conditions, etc. fossil fuels cause numerous environmental pollutions. in other words, on the one hand poisonous gases enter the environment fo...
renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. this paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. a speed control regulator is utilized to control the dc bus voltage. the inverter gate’s signals...
An important source of energy which has been considered in recent years in advanced countries is the wind energy which is very cheap, clean, and always available. The layout of turbines in the wind farm needs accurate calculations due to limited land and investment, so as to obtain the maximum energy from the wind farm. In this research to locate the turbines in a wind farm three approaches has...
Introduction: Energy as a contributor to human well-being plays an important role in the sustainable development of human societies. The growing demand for energy, higher standards of living, global warming, and decreasing fossil fuel resources have focused the global attention on renewable energies (Kaya and Kahraman, 2010). Owing to the rapid development of wind energy extraction technologies...
Wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. Owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. In general, these wind power p...
