Operating reserve requirements and equipment ranking in systems with renewable sources

摘要

This work presents a new method to evaluate generation reserve margins in systems with renewable sources. In assessing the adequacy of generation reserve amounts, besides failures in generating units, their capacity intermittencies, unavailability and capacity limits of the transmission system are properly considered. Risk indices are evaluated using quasi-sequential Monte Carlo simulation techniques. The cross-entropy method is used to treat rare events and also to rank critical equipment for operating reserve requirements in each scenario. The proposed method is applied to the IEEE RTS system considering a modified configuration with insertion of wind power plants.
