AbstractIn recent years, power system have become more complex with interconnections to neighboring systems for economic and reliability proposes. Deregulated structure and unbundled in between generation, transmission and distribution also emerging in many system. In economic operation of power systems, OPF plays an important role in both day to day operation and planning study of power systems. The conventional power flow model using single swing bus concept is based on many assumptions which are not valid in practical operation especially in modern power systems mentioned above. The analysis methods for economic operation of power systems under deregulation are necessary to be able to notice system characteristic under deregulation. This study presents a methodology for optimum real power generation scheduling in power systems considering generation control and load characteristics. The economic scheduling is obtained using closed loop A-method. The objective of the monopoly systems is to minimize the total fuel cost. In modern deregulated power systems the Pool's objective is to minimize of total generation cost, while the participants objective are maximization of their own benefits by least-cost operations in their owns subsystems after transaction is defined. The method provides fast and near practical solution suitable for modern power systems both monopoly and deregulated structure. Game theory is applied to analyze the characteristics of the participants in deregulated power markets. Dynamic programming is used for solving unit commitment problem as a separated problem from economic dispatch.
