Importance of Gas-Fired Power Plants Location in Integrated Operation of Power and Natural Gas Systems: Peak Load Condition Analysis

摘要

The increasing use of natural gas for power generation has caused a sudden improvement in interdependence between the two networks. These networks were analyzed traditionally as independent systems. In IRAN, Power Company is known as leader and Gas Company as a follower in the energy market. This situation imposes unfair charges on Gas Company. The aim of this paper is to determine the real operation cost of both systems. In this paper, an integrated operation of electricity and natural gas systems is used. Alternative fuel is considered as an effective peak shaving method in cold winters. The proposed model focused on the role of compressors in integrated optimization and obtain their fuel cost as an important decision variable. The applicability of the proposed approach has been demonstrated by analyzing a single branch gas pipeline network combined with the IEEE-9 test system. Simulations illustrate the importance of the location of power plants along the pipeline. The proposed model can be used to decide on the operation and planning of a coordinated electricity and natural gas systems.
