Reliability evaluation incorporating the load following capability of wind generation

Public concerns about adverse environmental impacts from conventional energy sources are causing a considerable increase in wind penetration in electric power systems as wind power is environmentally friendly and suitable for bulk power generation. The importance of accurate but simple wind resource models is becoming increasingly important as wind penetration continues to increase to carry out a realistic evaluation of system reliability. Analytical methods using annual wind models have generally been used for reliability evaluation of wind integrated systems. These methods do not recognize load following capability of wind. Seasonal period analysis can incorporate seasonal load following capability of wind. This paper evaluates the system adequacy indices on an annual and seasonal basis and then develops a technique to incorporate the diurnal load following capability of wind.
