| Abstract | Economic operation of the power system has been one of its main operating concerns. To achieve this, Economic Load Dispatch (ELD) is used as part of the modern energy management system. Economic load dispatch minimizes the total generation fuel cost of thermal plants while satisfying various system constraints. A deterministic model of ELD has been generally adopted based ori the forecasted load demand in the system. However, loads, in general, vary randomly and hen_ce, a probabilistic formulation of the economic load dispatch is required. Due to increased awareness of environmental pollution caused by electric power industry, strategies involved in power system operation are now giving equal importance to both minimum cost and minim~ emission operation. Economic Emission Dispatch aims to achieve a compromise between these two objectives. The present study formulates both deterministic and probabilistic models of economic emission dispatch and implements on Myanmar Power System as case study. It is found that whenever minimum cost of operation is taken as sole objective, the emission level increases. Similarly, minimum emission . dispatch results into higher operating cost. Therefore, both objectives are conflicting in nature and some weights must be given to obtain a non-inferior solution. A trade-off curve has been obtained which can be taken as guideline to fix the desired level of emission and cost toget~er by the operators. Impact of the economic emission dispatch on C02 emission has been, possibly, studied for the first time. The other type of emission considered in the study is NOx emission. A practical ramp-rate constraint of turbine generators has also been included in the model. The results have been obtained by considering constraint on the total maximum emission level in the system. The probabilistic economic emission dispatch has been solved with assumed random . variation of loads. A new method has been introduced to compute the variances of generation uncertainty which have been utilized to compute mean values of the total operating cost and total emission level. |
