Planning Wind Power Considering System Reliability in Peak Demand Time

This paper describes an integrated power capacity planing model that considers the contribution of wind power to system reliability in peak demand periods. Seasonal expected energy production of wind power is used to account for the reliability contribution of wind power. In order to minimize expansion cost over a long term planning horizon, primary alternatives of power expansion are included. Mixed integer programming (MIP) is used in the modeling. Case studies are presented to show that a region with lower wind speed in peak time requires a significant amount of peaking generators to compensate for low wind power availability in order to meet the required reserve.
