| Abstract | Economic operation of power system has been one of major operating concerns under the least cost production principle. Economic load dispatch (ELD) is used as a part of the modern energy management system whose objective is to minimize the total generator fuel cost of thermal power plants while satisfying various constraints. Several conventional optimization approaches have been used to solve the ELD problem. However, these methods require some unfavorable assumptions, such as continuity and differentiability of the objective function, which always lead to the failure to reach global minima. Due to the increasing awareness of environmental problems caused by electric power industries and the enforcement from environmental protection laws, operational paradigm of power system are now having to give the equal importance to both minimum cost and minimum emission. Combined emission and economic dispatch (CEED) presented in this thesis aims to optimize two objectives simultaneously. To achieve those two goals, this thesis proposed an application of parallel improved evolutionary programming (PIEP) to solve the optimal power flow problem with the CEED objective. The proposed PIEP was implemented on the AIT Optima Beowulf cluster and showed good effectiveness to speedup the computing process. The standard IEEE 30-, and modified 57- bus systems were chosen as case studies. Generator fuel cost and emission functions were modeled in quadratic forms. The simulation results showed that the developed algorithms in this thesis, particularly PIEP, can provide almost the same quality of solutions in terms of generator fuel cost. However, PIEP performs much better in term of computing time without sacrificing the quality of solutions. |
