High wind penetration in a small power system can create overwhelming stability issues at contingencies. Hybrid wind and pumped-storage systems are widely adopted to harness the maximum wind energy potential locally. Similarly, integration of pumped-storage power plants can be considered for islands or small power systems to integrate more wind farms while improving stability of the system. A small power system was derived based on the IEEE-12 bus system to evaluate the system behavior with increased wind penetration and pumped-storage integration. The integrated system was simulated in PSCAD/EMTDC to analyze the system transient stability under different scenarios. The studies revealed that the integration of pumped-storage systems into small power systems with high wind penetration not only supports more wind penetration into the system but also improves the transient stability.

Wind resource assesment and turbine selection : case study for Mannar, Sri Lanka
Kalpage, KMT; Peiris, KRD; Perera, KAIRP; Siriwardana, MGCI; Lidula, NWA
In deploying a large scale wind power plant, there are several aspects that have to be assessed. Among them the initial site screening for wind power plants, wind data assessment and proper selection of wind turbines are vital for the success of the project. This paper presents a step by step analysis in selecting a wind turbine, as a case study for Sri Lanka, where it has a substantial amount of wind energy that can be harnessed for power generation. Mannar area is identified as the candidate site with the high wind potential it exhibits throughout the year. After a detailed analysis of the wind resource in Mannar area, Gamesa-114 2 MW wind turbine is selected as the most suitable wind turbine for this particular area of Sri Lanka.
