Gas turbines and electric distribution system

Abstract:

Lately, the use of gas turbines following the deregulation of the electricity supplyindustry has become greater quickly. The motivation for modeling the gas turbines andtheir controllers is determinant to the interpreting of their impacts on distributionsystems. The model pbkp_redictive control (MPC) is used to damp the oscillation when thepower distribution system is subjected to a disturbance. MPC is selected because it canexplicitly handle the nonlinearities, and constraints of many variables in a single controlformulation. The IEEE 13 node power distribution system is employed to demonstratethe effectiveness of MPC to damp the oscillations of gas turbines.Among fossil fuels, gas is the most quickest, with a growth rate nearly double that ofcoal and oil. The electricity generation field is the leading market for gas. The natural gasbusiness has a great interaction with the electricity market in terms of fuel consumptionand energy conversion. On the other hand, the transmission and distribution activities arevery similar with the natural gas transportation through pipelines. The power losses in gasand electric systems are compared. It is also demonstrated that the electricity systemresults more convenient for longer distances of gas wells from electricity consumptionarea. © 2011 by Nova Science Publishers, Inc.
