Reliability assessment of wind power generation system

What are the main researches for wind power reliability evaluation?

Next, current main researches for wind power reliability evaluation are discussed, such as: wake effect, correlation of output power for different windturbines, effect of windturbine parameters, penetration and environment. Finally, it is been described about the reliability indices.

How does wind power affect the reliability of power system?

The fundamental difference is that the wind power is intermittent and uncertain. Therefore, it affects the reliability of power system in a different manner from that of the conventional generators. This paper, from available literatures, presents the model of wind farms and the methods of wind speed parameters assessment.

What are the reliability indices of wind power?

There are also some new reliability indices to describe the character of wind power, such as wind generation interrupted energy benefit, wind generation interruption cost benefit, Equivalent Capacity Rate, load carrying capacity benefit ratio. 2. Wind farm model 2.1. Wind speed model Energy from the wind is a form of solar energy.

How to evaluate a composite power system with wind power integration?

Thus, there is a pressing need for studying the reliability evaluation of composite power system with wind power integration. The composite power system reliability evaluation generally involves three basic steps: selecting system states, evaluating the consequences of selected system states and calculating risk indices .

What is power system reliability assessment?

Power system reliability assessment The reliability associated with a power system, in a general sense, is a measure of the overall ability of the system to generate and supply electrical energy. Power system reliability can be further divided into the two distinct categories of system adequacy and system security .

What is the reliability worth of adding wind generation as an alternative supply?

The reliability worth of adding wind generation as an alternative supply can be represented by an index designated as the wind generation interrupted energy benefit , . (22) WGIEB = EEN S bw − EEN S aw Incremental WTG capacity where EENS aw and EENS bw represent the energy not supplied after and before adding WTG units respectively.
