Abstract

Summary form only given. The significant expansion of wind power capacity in the Electric Reliability Council of Texas (ERCOT) will increase the amount of ancillary services (AS) necessary to maintain ERCOT system frequency targets. This paper analyzes ERCOT regulation adequacy from a simplifed dynamical model of ERCOT validated by empirical data. The model includes a representation of system frequency response characteristics; a stochastic, empirical-based model of wind power expansion; and a model of net load forecast error based on current performances. The simulation uses current ERCOT methodology for determining regulation, and NERC Balancing Authority Standards to examine frequency control performance.
