In response to emerging market conditions, and in recognition of the unique operating characteristics of wind generation, the New York Independent System Operator (NYISO) and New York State Energy Research and Development Authority (NYSERDA) commissioned a joint study to produce empirical information that will assist the NYISO in evaluating the reliability implications of increased wind generation. The work was divided into two phases. Phase 1, Preliminary Overall Reliability Assessment, was completed in early 2004. This initial phase provided a preliminary, overall, screening assessment of the impact of large-scale wind generation on the reliability of the New York State Bulk Power System (NYSBPS). Phase 2 builds on what was learned in Phase 1. A base case wind scenario with 3,300 MW of wind generation (10% of NY State peak load) was selected for analysis. Operation of the NYSBPS with 3,300 MW of wind was evaluated in numerous ways, considering impacts on the following aspects of grid performance: • Reliability and generation capacity; • Forecast accuracy; • Operation of day-ahead and hour-ahead markets; • Economic dispatch and load following; • Regulation; • Stability performance following major disturbances to the grid. Detailed analysis of economic impacts and evaluation of possible generator retirements were not included in the scope of this study. Results of these Phase 2 analyses are presented in this report.
