“…DFIG-VSWT allows full control of the most important variables and so, many control policies have been investigated and adopted: maximum power tracking policy (MPT) [2], active power regulation [3], reactive power/power factor/terminal voltage control [4], [5], [8].…”

“…In order to allow increasing penetration levels, control strategies beyond the maximum power tracking policy (MPT) [2] have been investigated, including active power regulation [3], reactive power and/or voltage control [4], [5] besides other approaches [6]. In early technology, mainly fixed-speed wind turbines equipped with squirrel cage induction generators were employed and still are in use in many medium size wind farms.…”

This paper considers the problem of grid integration of wind power. The integration level, i.e., the amount of wind power that can be connected to a given point of the grid while complying with certain interconnection requirements is determined for 6 different cases of induction generator based wind turbines, both with fixed and variable speed. Acceptable terminal voltage variation, power transfer margin, and acceptable range for the internal voltage angle are taken as criteria for the analysis of the attainable integration level, which is provided in terms of the point-of-common-connection parameters, namely the shortcircuit power and the X/R ratio. Results show the profile of the limits imposed by each individual criterion on the wind power integration level, as a function of the X/R ratio. The set of integration levels satisfying all criteria simultaneously is characterized as a safe integration region. The 6 cases considered are compared regarding the attainable integration level.

“…In the Nordic system, for instance, the flexibility of hydro power can be beneficial to meet the power variations induced by wind power as it is demonstrated in [32]. It is shown how hydro power plants can balance wind farms using a local AGC scheme developed in [33]. Also, the analysis of a loss of 1700 MW wind power in seven hours in Denmark (with a maximal loss of 550 MW per hour) demontrates the ability of hydro power in the rest of the Nordic system to absorb large variations.…”

This paper reviews studies concerning new challenges for European transmission system operators (TSOs) when operating primary, secondary and tertiary reserves in a system with large amounts of wind power. The review adopts three perspectives. First, the impact on existing markets is discussed and it is shown that need for additional reserve requirements does not necessarily mean need for new reserve capacity. Secondly, possible designs of improved load-frequency control schemes are presented. The proposed solutions exhibit a trend towards market-based procurement mechanisms and automation of reserve operations. Finally, participation of wind power in load-frequency control is examined. Technical designs are presented for participation in primary control.

Europe: Status of Integrating Renewable Electricity Production into the Grid

The visionary targets of the European Community were to increase the share of renewable energy resources between 1997 and 2010 from 14 to 22 % as well as to double the contribution of cogeneration plants for heat and power (CHP) on total electricity production from 9 to 18 %. Consequently, the share of dispersed and renewable energy resources (DER) would cover 40 % of the whole electricity production in 2010. All countries have set their own targets to reach the common goal.The DER in distribution systems will achieve an additional growth of more than 300 TWh/a to meet the challenging European targets. Additionally, wind power will grow primarily in the form of large wind farms that centrally feed into the transmission grids with 20-30 GW installed power by 2010. Large offshore wind farm sites with rated power up to 1,000 MW are currently under investigation to be installed in the North and in the Baltic Seas.However, the output of most of the renewable energy sources depends on meteorological conditions and the CHP output is normally driven by the demand for heat that is higher in winter and lower in summer periods. The full load hours of the installed wind power capacity, for example, are approximately 1,400-1,600 h/a at onshore locations and between 800 and 1,000 h/a for photovoltaic plants.
