Wind power is expected to contribute significantly to the renewable energy targets owing to advancements in wind technologies, falling capital costs, abundance of free resource and commercial viability. However, it also brings into a lot of new challenges for the power network planning and operation. The predictability of wind power in managing load and generation balance is very important. If the...
In this paper impact of wind farm in power system reliability is investigated and a new procedure for reliability evaluation of power systems with wind farm in HLI is proposed. The proposed method is capable of finding both loss of load expectation (LOLE) and loss of energy expectation (LOEE) analytically in the presence of wind power. A wind farm in the north-western region of Iran is studied in...
Growing of wind power has resulted in a need for evaluation of its impact on power systems planning and operation. This paper analyzes the benefits of regulating wind power for power systems. A new unified index will be introduced to comprehensively evaluate the performance of the system with wind power at different possible locations, considering not only the benefits of loss reduction and voltage...
The calculation of penetration limits of wind farm is an important issue on the planning of wind farm, Basing on reliability modeling of wind farm, this paper proposes a method to calculate penetration limits of wind farm by taking reliability index as restriction. Since load demand and output of wind farm are of randomicity, and the restriction is expressed as form of reliability, Monte Carlo method...
With the increased use of wind energy for the power generation several TSO have increasing difficulties for congestion forecasting due to the unpredictable nature of the energy source. An actual method used to deal with days-ahead congestion planning is based on an order of disconnection of the generation of the type ldquolast generation installed, first generation limitedrdquo. This paper proposes...
Wind energy will continue to grow at a rapid pace and will provide an increasingly large portion of the total electricity generation. To achieve its full potential, the industry needs adequate wind-turbine generator (WTG) dynamic models to determine the impact of adding wind generation, and establish how the system needs to be upgraded.For the most part, WTG manufacturers have sponsored the development...
As the size and number of wind power plants (WPP) increases, power system planners will need to study their impact on the power system in more detail. As the level of wind power penetration into the grid increases, the transmission system integration requirements will become more critical [1-2]. A very large WPP may contain hundreds of megawatt-size wind turbines. These turbines are interconnected...
The effective load carrying capability (ELCC) is considered the preferred metric to evaluate the capacity value of a wind farm when performing generation expansion studies. Unfortunately, the classical implementation of the ELCC concept requires substantial reliability modeling and a computationally-intensive iterative process. The non-iterative method developed as part of our previous work addresses...
This paper presents an advanced statistical method for wind power forecasting based on artificial intelligence techniques. The method requires as input past power measurements and meteorological forecasts of wind speed and direction interpolated at the site of the wind farm. A self-organized map is trained to classify the forecasted local wind speed provided by the meteorological services. A unique...
As the size and number of wind power plants (also called wind farms) increases, power system planners will need to study their impact on the power system in more detail. As the level of wind power penetration into the grid increases, the transmission system integration requirements becomes more critical. A very large wind power plant may contain hundreds of megawatt-size wind turbines. These turbines...
