Effects of penetration level and location of wind turbines on shadow prices and congestion of transmission lines

Abstract

This paper studies the effects of wind power on electricity market parameters. The penetration level of wind energy, location of wind turbines, and integration of multiple wind turbines are the main topics addressed in this paper. Flow-gate marginal pricing is the main electricity market concept which is analyzed and studied. Stochastic programming including wind power uncertainty is presented to minimize the annual operational cost of generators. The Flow-gate marginal pricing of transmission lines is also calculated. The Flow-gate marginal pricing is scrutinized under various wind power sizing, siting, and settings. The location, number, and capacity of wind turbines are changed to find out their impacts on the network Flow-gate marginal pricing. The proposed analyses and simulations are carried out using general algebraic modeling system software.
