This paper concerns the implications of adding wind power on the Northeast Power Coordinating Council (NPCC) US electric power system operations and costs. Constrained Economic Dispatch Optimization Model (CEDOM) has been performed by utilizing wind power every 10 minutes. We illustrate the results of such economic dispatch on NPCC power system where seasonal wind and load power variations are considered in the CEDOM over three days in different seasons. Analysis of the most congested hour has been investigated and effects of congestion on Locational Marginal Price (LMP) are discussed. Finally, we study the sensitivity of LMP to net power injections and line flows by comparing CEDOM results using AC Optimal Power Flow (ACOPF) with DCOPF. The results indicate a divergence problem occurring at highly injected nodes and a decrease of LMP values in locations with increased net power injections.
